How to Test a Golf Cart Solenoid with a Multimeter: Easy Steps

Is your golf cart refusing to start, making strange clicking noises, or suffering from intermittent power? These frustrating issues often point towards a vital component in your cart’s electrical system: the solenoid. Learning how to check solenoid on golf cart is a fundamental troubleshooting skill that can save you time, money, and unnecessary trips to the repair shop.

Many golf cart owners feel intimidated when faced with electrical diagnostics, often unsure where to begin or worried about causing further damage. Dealing with a silent ignition, a cart that clicks but won’t budge, or power that cuts out unexpectedly can quickly turn a leisurely ride into a headache. The uncertainty of whether the issue is the battery, the motor, or something in between adds to the stress.

Testing your golf cart solenoid involves inspecting its connections, listening for an activation ‘click’ when the accelerator is pressed (with the key on), and using a multimeter to verify correct voltage flow across its terminals during activation. This confirms if the solenoid is properly switching power from the battery to the motor.

Understanding this process empowers you to accurately diagnose one of the most common failure points in electric golf carts. This guide provides clear, step-by-step instructions derived from expert sources and common repair practices, ensuring you can confidently test your solenoid. We’ll cover the symptoms of a faulty solenoid, the necessary safety precautions, detailed multimeter testing procedures, and what to do if a replacement is needed, helping you get your cart running smoothly again.

Key Facts:
* Critical Switch: A golf cart solenoid acts as a heavy-duty electromagnetic switch, essential for connecting the high-amperage current from the battery pack to the motor upon acceleration.
* Common Failure Point: Due to the high currents they handle and exposure to vibrations and environmental factors, solenoids are one of the most frequently replaced electrical components in golf carts.
* Voltage Specific: Solenoids are voltage-specific (e.g., 36V or 48V) and must match the golf cart’s electrical system voltage for proper operation and longevity. Using the wrong voltage can lead to immediate failure or damage.
* Audible Cue: A distinct “click” sound upon pressing the accelerator (with the key on) is a primary indicator that the solenoid’s activation circuit is receiving power and attempting to engage, though it doesn’t guarantee the main contacts are working.
* Safety First: Testing requires working with the cart’s electrical system; always implement safety measures like turning the key off, setting the parking brake, and disconnecting the main negative battery cable before touching terminals or performing resistance tests.

What is a Golf Cart Solenoid and Why is Testing It Important?

A golf cart solenoid is essentially an electrical relay or switch designed to handle the high current required to power your golf cart’s motor. Think of it as a gatekeeper; it takes a small electrical signal (triggered when you turn the key and press the accelerator) and uses it to close a much larger, more robust internal connection, allowing the full power of your battery pack to flow to the motor. Testing this component is crucial because if the solenoid fails, this vital connection isn’t made, leaving your cart powerless or performing erratically.

Properly diagnosing a solenoid helps you pinpoint electrical issues accurately. Instead of guessing whether the problem lies with the batteries, controller, motor, or wiring, testing the solenoid provides a definitive answer about its operational status. This prevents unnecessary replacement of more expensive components and gets you directly to the root cause of the problem, ensuring a faster and more cost-effective repair. It’s a fundamental step in troubleshooting many common golf cart electrical faults.

Understanding the Solenoid’s Role in Your Cart

The solenoid sits between your battery pack and the motor (often via the controller). When you turn the key and press the accelerator pedal, a low-amperage electrical signal is sent to the solenoid’s two small activation terminals. This signal energizes an internal electromagnet (coil).

The energized electromagnet pulls a plunger, which forces two large internal contacts together. These large contacts bridge the connection between the two large terminals on the outside of the solenoid. One large terminal is connected to the main positive battery feed, and the other leads towards the motor controller and then the motor. When these contacts close, the high-amperage circuit is completed, and power flows, allowing the motor to turn the wheels. Releasing the pedal de-energizes the coil, a spring retracts the plunger, the contacts open, and power flow stops.

Why You Might Need to Test Your Solenoid

Testing your golf cart solenoid becomes necessary when you experience symptoms indicating a potential electrical failure in the main power delivery circuit. Identifying a faulty solenoid early can save significant diagnostic time. Here are common reasons to perform a solenoid test:

• Cart Won’t Start: The most common reason. You turn the key, press the pedal, but nothing happens – no movement, maybe not even a click.
• Audible Clicking, No Movement: You hear one or more clicks from the solenoid area when pressing the accelerator, but the cart doesn’t move. This often indicates the activation circuit is working, but the main contacts aren’t making a good connection.
• Intermittent Operation: The cart works sometimes but fails at others, or it might cut out while driving. This can point to failing solenoid contacts or a weak activation coil.
• No Clicking Sound: You press the pedal, and there’s complete silence from the solenoid area, suggesting the activation circuit isn’t receiving power or the internal coil has failed.
• Troubleshooting Power Loss: If the cart suddenly loses power or feels sluggish, testing the solenoid helps rule it out as the cause before investigating batteries or the motor.
• After Replacing Other Parts: If you’ve replaced batteries or other components and the cart still won’t run, the solenoid is a prime suspect.

What are the Common Symptoms of a Bad Golf Cart Solenoid?

A failing golf cart solenoid often presents specific, recognizable symptoms that signal an interruption or inadequacy in the power transfer from the battery to the motor. Recognizing these signs is the first step in diagnosing a potential solenoid issue. While other components can cause similar problems, these symptoms strongly suggest the solenoid should be tested promptly.

The most frequent indicators include issues with the activation click, the cart’s responsiveness to the accelerator, and sometimes physical signs on the solenoid itself. Paying attention to exactly how the cart is failing (e.g., clicking vs. silent, intermittent vs. complete failure) provides valuable clues. Understanding these common failure modes helps differentiate a solenoid problem from, say, a battery issue or a motor fault.

No Clicking Sound

When you turn the key to the ‘on’ position and press the accelerator pedal, a healthy solenoid should produce a distinct, audible “click” as its internal electromagnet activates and closes the main power contacts. If you press the pedal and hear absolutely nothing from the solenoid area, it’s a strong indicator that the solenoid isn’t activating. This could mean the solenoid’s internal coil has failed, or the activation signal isn’t reaching the small terminals due to wiring issues, a faulty microswitch in the accelerator linkage, or a problem with the key switch circuit.

Excessive Clicking Without Movement

Sometimes, instead of a single click, you might hear rapid or repeated clicking sounds from the solenoid when you press the accelerator, but the cart still refuses to move. This usually signifies that the solenoid’s activation circuit is receiving power (hence the clicking), but the main internal contacts are damaged, burnt, pitted, or misaligned. They are trying to make a connection but fail to establish a solid path for the high current needed by the motor. Low battery voltage can also sometimes cause chatter, so ensure your batteries are adequately charged before condemning the solenoid solely based on this symptom.

Intermittent Operation

A golf cart solenoid nearing the end of its life can cause the cart to operate sporadically. It might start and run perfectly one moment, then refuse to engage the next, or it could cut out while driving and then start working again after a short wait. This unreliability often stems from internal contacts that are partially damaged or worn, making inconsistent connections. Temperature changes or vibrations can sometimes influence this intermittent behavior, making diagnosis tricky without direct testing.

Burning Smell or Visible Damage

In cases of severe failure or overheating, you might notice a distinct electrical burning smell emanating from the solenoid’s location (usually near the batteries or controller). A visual inspection might reveal physical damage such as a cracked casing, melted plastic around the terminals, signs of arcing (black marks), or severe corrosion on the terminal posts and wire connections. Any such visible damage is a clear indication that the solenoid has failed and requires immediate replacement for safety reasons.

How Do You Prepare to Check the Solenoid on Your Golf Cart?

Proper preparation is essential for safely and effectively checking your golf cart solenoid. Before diving into any testing procedures, taking a few key preparatory steps will protect both you and your cart’s electrical system. This involves gathering the right tools, implementing crucial safety measures, correctly identifying the solenoid, and performing a quick visual check.

Skipping preparation can lead to inaccurate test results, damage to electrical components, or even personal injury. Electrical systems in golf carts carry significant current, especially from the battery pack. Treating these systems with respect and following a methodical approach ensures the testing process is smooth and conclusive.

Gathering Necessary Tools and Safety Gear

Having the right equipment on hand makes the testing process much easier and safer. You don’t need a vast toolkit, but a few specific items are essential:

• Digital Multimeter (or Voltmeter): This is your primary diagnostic tool for measuring voltage and continuity (resistance/ohms). Ensure it has settings for DC Voltage (VDC) suitable for your cart’s voltage (e.g., up to 50V or more) and Continuity/Ohms (Ω).
• Wrenches/Sockets: You’ll likely need wrenches (often ½” or 9/16”, but sizes vary) or sockets to disconnect battery cables and potentially loosen/remove solenoid terminal nuts if needed for continuity tests or replacement.
• Screwdrivers: May be needed depending on how components are mounted or if covers need removal.
• Wire Brush: Useful for cleaning any corrosion found on terminals.
• Safety Goggles: Absolutely essential to protect your eyes from potential sparks or debris.
• Insulated Gloves: Provide an extra layer of protection against accidental electrical contact.
• Golf Cart Service Manual (Optional but Recommended): Provides exact locations and wiring specifics for your model.

Implementing Critical Safety Precautions

Safety is paramount when working on any vehicle’s electrical system. Golf cart batteries store significant energy. Follow these steps rigorously:

1. Park on Level Ground: Ensure the cart is stable.
2. Engage Parking Brake: Prevent accidental rolling.
3. Turn Key OFF: Remove the key from the ignition completely.
4. Set Tow/Run Switch to TOW (if applicable): This disconnects power to the controller on many modern carts, providing an extra safety layer. Consult your manual if unsure.
5. Disconnect Main Negative Battery Cable: Using the correct size wrench, ALWAYS disconnect the main NEGATIVE (-) battery terminal FIRST. This breaks the main ground connection for the entire high-amperage system, significantly reducing the risk of accidental shorts if your wrench touches the frame while working on positive terminals. Tuck the cable away securely so it cannot accidentally contact the terminal.
6. Wear Safety Gear: Put on your safety goggles and gloves before touching any components.

Locating the Solenoid on Your Cart

The solenoid is typically a cylindrical or rectangular component, often made of metal or heavy-duty plastic, with four terminals (posts). Two large terminals handle the high current to the motor, and two smaller terminals receive the activation signal.

Its location varies slightly by manufacturer and model (EZGO, Club Car, Yamaha), but it’s almost always found:

• In the main battery compartment.
• Mounted near the motor controller.
• Sometimes attached near the starter/generator on gas carts (though this guide focuses on electric cart main solenoids).

Look for a component connected by heavy gauge wires (similar thickness to battery cables) to the battery pack and the motor controller. The smaller terminals will have thinner wires connected to the key switch and accelerator pedal circuit. If unsure, consult your golf cart’s service manual for the precise location.

Performing an Initial Visual Inspection

Before connecting your multimeter, take a moment to visually inspect the solenoid and its connections:

• Terminals: Check the large and small terminals for signs of corrosion (white or bluish powder), rust, or physical damage. Ensure the nuts securing the wires are tight. Loose connections are a common cause of failure and overheating.
• Wiring: Look for frayed, cracked, burnt, or melted insulation on the wires connected to the solenoid. Ensure wires are securely fastened under the terminal nuts.
• Solenoid Casing: Inspect the body of the solenoid for cracks, burn marks, or signs of melting or swelling.
• Cleanliness: Excessive dirt or corrosion build-up can sometimes cause issues. Clean the terminals gently with a wire brush if needed (ensure battery is disconnected!).

Addressing any obvious issues like loose connections or heavy corrosion might even solve your problem without further testing.

How to Check Solenoid on Golf Cart with a Multimeter?

Using a multimeter is the most definitive way to determine if your golf cart solenoid is functioning correctly. This involves performing specific voltage and continuity tests across its terminals under different conditions (key off, key on/pedal pressed). These tests verify both the activation circuit (small terminals) and the main power switching capability (large terminals).

Following a systematic testing procedure ensures accurate results. Remember to observe all safety precautions outlined earlier, particularly ensuring the main negative battery cable is disconnected for continuity tests and reconnected carefully for voltage tests where activation is required.

Setting Up Your Multimeter

Correctly configuring your multimeter is crucial for obtaining accurate readings and preventing damage to the meter or the cart’s electrical system.

1. Select Function:
   • For Voltage Tests: Turn the dial to the DC Voltage setting (marked as VDC, V–, or a V with a straight line and dashes). Ensure the selected range is higher than your cart’s system voltage (e.g., use the 200VDC range if available for a 36V or 48V cart, or the lowest setting that’s still above your system voltage).
   • For Continuity/Resistance Tests: Turn the dial to the Ohms setting (marked with the Greek letter Omega: Ω). Some meters have a dedicated continuity setting (often marked with a sound wave symbol) that beeps when continuity is detected (low resistance).
2. Probe Placement:
   • Plug the black probe lead into the COM (Common/Ground) port.
   • Plug the red probe lead into the port labeled VΩmA (or similar – the one used for measuring Voltage and Ohms).

Testing Voltage Across the Large Terminals

This test checks if the solenoid is successfully closing the high-current circuit when activated. Safety Note: For voltage tests requiring activation, the main negative battery cable must be reconnected. Be extremely cautious not to short terminals with tools or probes.

1. Reconnect Battery: Carefully reconnect the main negative battery cable.
2. Key ON, Pedal PRESSED: Turn the ignition key ON and fully press the accelerator pedal to activate the solenoid (you should hear the click if the activation circuit is working).
3. Measure Voltage: Place the black multimeter probe on the large terminal where the main battery positive cable connects. Place the red probe on the other large terminal (the one leading towards the controller/motor).
4. Interpret Reading:
   • Good Solenoid: You should read the full battery pack voltage (approximately 36V for a 36V system, 48V for a 48V system) across the large terminals. This indicates the internal contacts have closed and power is flowing through.
   • Bad Solenoid: If you read zero volts or a significantly lower voltage (despite hearing a click), the internal contacts are not making a proper connection. The solenoid needs replacement.
   • Bad Solenoid (Alternative Check): Some guides suggest checking voltage from each large terminal to the main battery negative post while activated. You should see full battery voltage on both large terminals if the solenoid is working correctly. If you only have voltage on the incoming terminal but not the outgoing one, the solenoid is faulty.
5. Key OFF: Release the accelerator and turn the key OFF.

Checking the Activation Circuit (Small Terminals)

This test verifies if the solenoid’s internal coil is receiving the necessary voltage to activate when you press the pedal.

1. Battery Connected: Ensure the main negative battery cable is connected.
2. Key ON, Pedal PRESSED: Turn the ignition key ON and fully press the accelerator pedal.
3. Measure Voltage: Carefully place the multimeter probes across the two small terminals on the solenoid (polarity usually doesn’t matter for this check).
4. Interpret Reading:
   • Good Activation Circuit: You should read the full battery pack voltage (approx. 36V or 48V, depending on your system). This confirms the key switch, pedal microswitch, and wiring delivering the signal to the solenoid are working correctly.
   • Bad Activation Circuit (or Coil): If you read zero volts or significantly less than full battery voltage, the problem lies before the solenoid (key switch, pedal switch, wiring) OR the solenoid’s internal coil might be open (though less common). If you do get voltage here but the solenoid doesn’t click, the internal coil is likely bad.
5. Key OFF: Release the accelerator and turn the key OFF.

Testing Continuity Across the Large Terminals (Resistance Test)

This test directly checks the resistance across the main power contacts without power applied to the system. Safety Critical: The main negative battery cable MUST be disconnected for this test. It’s often easiest to perform this test if the solenoid is removed from the cart (bench test), but it can sometimes be done in place if wires are disconnected.

1. Disconnect Battery: Ensure the main negative battery cable is disconnected.
2. Disconnect Large Terminal Wires: Using the appropriate wrenches, carefully disconnect the heavy gauge wires from both large solenoid terminals. Ensure the loose wires cannot touch anything conductive.
3. Set Multimeter: Set your multimeter to the Ohms (Ω) or Continuity setting. Touch the probe tips together briefly; the meter should read near zero ohms or beep, confirming it’s working.
4. Test Deactivated State: Touch one probe to each of the large solenoid terminals.
   • Expected Reading (Good): The meter should read infinite resistance (often displayed as “OL,” “Open Line,” or 1) or show no continuity (no beep). This indicates the contacts are open when the solenoid is not activated.
5. Test Activated State (Requires Bench Test Setup or Helper): This step requires activating the solenoid while measuring continuity.
   • Method 1 (Bench Test – Recommended): Remove the solenoid. Use jumper wires connected to your cart’s battery pack (or a separate appropriate voltage source) to apply power momentarily across the two small activation terminals. While power is applied, re-measure resistance across the large terminals.
   • Method 2 (In Cart – Requires Helper & Caution): Have a helper turn the key ON and press the pedal (main battery must be reconnected only for activation, probes must already be on large terminals, wires must remain disconnected from large terminals). This method carries higher risk and is generally less preferred.
   • Expected Reading (Good): When activated, the resistance across the large terminals should drop to near zero ohms (typically less than 0.5 Ω), and the continuity tester should beep.
   • Bad Solenoid: If the resistance remains high (OL) or doesn’t drop significantly when activated, the internal contacts are faulty. If the resistance is near zero even when not activated, the solenoid is stuck closed (welded).
6. Disconnect Power/Key OFF: Stop applying power (bench test) or have the helper turn the key OFF. Reconnect wires if testing is complete and the solenoid is good, or proceed to replacement if faulty.

Interpreting Your Multimeter Readings

Summarizing the multimeter test results helps determine the solenoid’s condition:

Test	Condition	Probes On	Expected Reading (Good Solenoid)	Reading Indication (Bad Solenoid)
Voltage – Activation Circuit	Key ON, Pedal PRESSED	Small Terminals	Full Battery Voltage (36V/48V)	0V or Low Voltage (Activation issue/Coil)
Voltage – Main Circuit	Key ON, Pedal PRESSED	Large Terminals	Full Battery Voltage (36V/48V)	0V or Low Voltage (Contacts not closing)
Continuity – Main Contacts	Battery DISCONNECTED	Large Terminals	Infinite Resistance (OL) / No Beep	Low Resistance / Beep (Stuck closed)
Continuity – Main Contacts	Battery DISCONNECTED	Large Terminals	Near Zero Ohms ( < 0.5 Ω) / Beep	Infinite Resistance (OL) / No Beep
	but Solenoid ACTIVATED			(Contacts not closing)

Remember to always ensure your multimeter is set correctly and safety precautions are followed.

How Do Testing Procedures Differ for 36V vs. 48V Golf Cart Solenoids?

Fundamentally, the testing procedures using a multimeter are identical for both 36V and 48V golf cart solenoids. The steps for checking voltage across the small activation terminals and across the large power terminals, as well as testing continuity, remain the same regardless of the system voltage. You are still looking for the presence or absence of voltage and continuity under specific activation conditions.

The primary difference lies in the expected voltage readings you’ll obtain with your multimeter during the voltage tests. On a healthy 36V system, you should measure approximately 36-38 volts across the small terminals (when activated) and across the large terminals (when activated). On a 48V system, you should expect readings around 48-51 volts in the same tests. Your multimeter must be set to a DC voltage range capable of reading these higher voltages accurately (e.g., 200VDC range). Always ensure the replacement solenoid’s voltage rating matches your cart’s system voltage (36V or 48V).

What Are Other Ways to Test a Golf Cart Solenoid?

While using a multimeter provides the most comprehensive diagnostic information, there are simpler tests you can perform, especially if a multimeter isn’t available or if you want quick confirmation. These methods include listening carefully for the activation click and performing a bench test if you remove the solenoid from the cart.

These alternative tests can be useful initial checks or supplementary verification steps. The “click test” is the most basic check, while a bench test allows for controlled testing of the solenoid’s core functions away from other potential system variables.

The “Click Test” – Listening for Activation

This is the simplest initial check. Ensure the area is relatively quiet.

1. Safety: Key OFF, Parking Brake ON.
2. Listen: Position yourself near the solenoid’s location.
3. Activate: Turn the ignition key ON and firmly press the accelerator pedal.
4. Interpret:
   • Loud, Single Click: This indicates the solenoid’s activation circuit (key, pedal switch, wiring to small terminals) is likely working, and the solenoid’s internal coil is energizing and attempting to close the main contacts. It doesn’t guarantee the main contacts are making a good connection, however. If you hear a click but the cart doesn’t move, suspect faulty main contacts (proceed to multimeter tests).
   • No Click: This points towards a problem in the activation circuit before the solenoid, or a failure of the solenoid’s internal coil. Check fuses, key switch, pedal microswitch, and wiring first. If those are okay, the solenoid coil may be bad (confirm with multimeter voltage test at small terminals).
   • Multiple Clicks/Chatter: Often indicates low battery voltage or poor main contacts within the solenoid. Charge batteries fully first. If chatter persists with charged batteries, the solenoid is likely faulty.

Performing a Bench Test

Bench testing involves removing the solenoid from the golf cart and testing it directly using a power source and a multimeter/continuity tester. This isolates the solenoid from the rest of the cart’s wiring.

1. Safety First: Ensure the cart’s main negative battery cable is disconnected.
2. Remove Solenoid: Label the wires connected to each terminal (take a photo!). Carefully disconnect all wires from the solenoid terminals. Unbolt the solenoid from its mounting position.
3. Gather Test Gear: You need the solenoid, a known good power source matching the solenoid’s voltage (e.g., your cart’s battery pack or a dedicated 36V/48V supply), jumper wires with alligator clips, and your multimeter set to Ohms/Continuity.
4. Test Continuity (Deactivated): With nothing connected, test continuity across the two large terminals using your multimeter. It should read infinite resistance (OL) or show no continuity (no beep).
5. Apply Power (Activation): Carefully connect jumper wires from your power source to the two small activation terminals on the solenoid. Polarity usually doesn’t matter for the coil, but check if marked. Apply power momentarily.
6. Listen & Test Continuity (Activated): When power is applied to the small terminals, you should hear a solid “click.” While power is still applied, quickly test continuity across the two large terminals again. It should now read near zero ohms and/or beep.
7. Remove Power: Disconnect the power from the small terminals. The click should sound again as it releases, and continuity across the large terminals should return to infinite (OL).
8. Interpretation: If the solenoid clicks loudly and shows the correct continuity changes (OL when off, near zero when activated), it is likely good. If it fails any part of the bench test (no click, doesn’t show continuity when activated, shows continuity when off), it is faulty.

What Should You Do If the Solenoid Test Indicates Failure?

If your tests definitively show the solenoid is faulty (e.g., no click with voltage present at small terminals, click but no voltage across large terminals, incorrect continuity readings), the only reliable solution is to replace it with a new, compatible unit. Attempting to repair solenoids is generally not recommended due to their sealed nature and the high currents they handle; replacement is safer and more effective.

Choosing the correct replacement and installing it properly are crucial for restoring your golf cart’s operation and ensuring long-term reliability. Taking care during the replacement process prevents damage to the new solenoid or other electrical components.

Selecting the Correct Replacement Solenoid

Choosing the right solenoid is critical. Using an incorrect part can lead to immediate failure, poor performance, or damage to other parts of the electrical system. Consider these factors:

• Voltage Rating: This is the most important factor. The solenoid must match your golf cart’s system voltage (e.g., 36V or 48V). Using a 36V solenoid in a 48V system will quickly burn it out. Using a 48V solenoid in a 36V system might not activate reliably. The voltage is usually stamped on the solenoid casing.
• Duty Cycle (Continuous vs. Intermittent): Most golf cart main power solenoids are “intermittent duty,” designed for the short bursts of activation during acceleration. Some systems might use “continuous duty” solenoids (less common for main power). Ensure you get the correct type specified for your application. Heavy-duty options are often available for upgraded carts.
• Terminal Configuration: Ensure the new solenoid has the same number and arrangement of large and small terminals as the old one.
• Mounting Bracket: Check that the mounting bracket matches the old unit for easy installation.
• Compatibility: Purchase from reputable golf cart parts suppliers. Provide your cart’s make (EZGO, Club Car, Yamaha), model, and year to ensure you get the correct OEM or high-quality aftermarket equivalent.

Step-by-Step Solenoid Replacement Guide

Replacing the solenoid is generally straightforward if you follow these steps carefully:

1. SAFETY FIRST: Ensure the key is OFF, the parking brake is set, the Tow/Run switch is in TOW (if applicable), and the main negative battery cable is DISCONNECTED. Wear safety goggles.
2. Label/Photograph Wires: Before disconnecting anything from the old solenoid, clearly label each wire or take a clear photo showing which wire connects to which specific terminal (especially important for the small activation wires). Mix-ups here can prevent the cart from working.
3. Disconnect Wires: Using the correct size wrenches, carefully remove the nuts securing the wires to the solenoid terminals. Start with the small terminals, then the large ones. Ensure the loose wire ends cannot touch each other or any metal parts of the cart.
4. Remove Old Solenoid: Unbolt the solenoid from its mounting bracket and remove it from the cart.
5. Position New Solenoid: Mount the new solenoid securely onto the bracket.
6. Reconnect Wires (CRITICAL): Referring to your labels or photo, reconnect the wires to the correct terminals on the new solenoid.
   • Small Terminals: Reconnect the activation wires first. Tighten the nuts snugly but do not overtighten, as these studs can break.
   • Large Terminals: Reconnect the heavy gauge battery and controller/motor cables. Ensure these connections are clean and tight. Loose connections here can cause overheating and failure. Tighten the large nuts securely.
7. Final Check: Double-check that all wires are connected to the correct terminals and that all nuts are tight. Ensure no tools are left in the battery compartment.
8. Reconnect Battery: Carefully reconnect the main negative battery cable to the battery terminal and tighten it securely.
9. Test Operation: Switch Tow/Run back to RUN (if applicable). Turn the key ON. Press the accelerator. Listen for the click and check if the cart moves.

If the cart now operates correctly, the faulty solenoid was likely the issue. If problems persist, further troubleshooting of other components (batteries, controller, motor, wiring, switches) is required.

FAQs About How to Check Solenoid on Golf Cart:

How do I know if my solenoid is bad on my electric golf cart?

Common signs include: the cart won’t start (silent or clicking), starts intermittently, makes rapid clicking sounds without moving, or you notice a burning smell or visible damage on the solenoid. Testing with a multimeter is the definitive way to confirm.

How do you test a solenoid to see if it’s bad?

The best way is with a multimeter. Check for activation voltage (usually full battery voltage) at the small terminals when the key is on and pedal pressed. Then check for full battery voltage passing across the large terminals when activated. Also, test continuity across large terminals (should be open when off, near zero ohms when activated – requires battery disconnect for safety).

Will a golf cart charge with a bad solenoid?

Generally, yes, a bad main power solenoid should not prevent the golf cart’s battery charger from working. The charging circuit is typically separate from the solenoid’s motor power switching function. However, if the solenoid failure is part of a larger electrical issue, charging could be affected indirectly.

How do you test a 48 volt golf cart solenoid with a multimeter?

The procedure is the same as for any voltage: check for ~48V across the small terminals when activated, check for ~48V across the large terminals when activated, and check continuity (OL when off, near zero ohms when activated). Ensure your multimeter is set to a DC Voltage range higher than 50V.

How do you test a 36v golf cart solenoid?

Follow the standard multimeter tests: check for ~36V across the small terminals when activated, check for ~36V across the large terminals when activated, and perform the continuity check (OL when off, near zero ohms when activated). Use an appropriate DC Voltage range on your multimeter.

What happens when a golf cart solenoid goes bad?

When a solenoid fails, it typically prevents the high-current power from reaching the motor. This results in the cart not moving, either silently or with clicking sounds. It can also cause intermittent operation or complete failure to start.

Why is my golf cart solenoid clicking but not moving?

This usually means the activation circuit is working (sending the signal to click), but the solenoid’s main internal contacts are damaged, burnt, or not making good enough contact to pass the high current required by the motor. Low battery voltage can also sometimes cause clicking without movement.

Can a solenoid work intermittently?

Yes, absolutely. As the internal contacts wear or corrode, they can make inconsistent connections, causing the solenoid to work sometimes and fail at others. This intermittent behavior is a common symptom of a failing solenoid.

Where is the solenoid usually located on an EZGO / Club Car / Yamaha?

While exact locations vary by model and year, the main power solenoid is typically found in the battery compartment or near the motor controller. It’s a cylindrical or rectangular component with two large and two small terminals connected by heavy and light gauge wires respectively. Consult your owner’s or service manual for specifics.

Do I need to disconnect the battery before testing the solenoid?

YES, absolutely disconnect the main negative battery cable before performing continuity/resistance tests or before physically touching/removing the solenoid terminals or wires. For voltage tests where the solenoid needs activation, the battery must be connected, but exercise extreme caution.

Summary:

Successfully checking the solenoid on your golf cart is a key diagnostic skill for any owner experiencing power or starting issues. The process involves understanding the solenoid’s function as a critical electrical switch, recognizing the common symptoms of failure like clicking without movement or intermittent operation, and performing systematic tests. While a basic “click test” offers initial clues, using a multimeter to verify voltage at the activation terminals and across the main power terminals, along with checking continuity, provides the most definitive assessment.

Remember that preparation and safety are paramount. Always gather the necessary tools (multimeter, wrenches, safety gear), implement safety precautions like disconnecting the main negative battery cable before touching terminals for continuity checks, and locate the solenoid correctly. Interpreting the multimeter readings accurately—comparing expected voltage (36V or 48V) and resistance values against your findings—will tell you whether the solenoid needs replacement.

If replacement is necessary, select the correct voltage-matched part and follow careful installation steps, ensuring all connections are clean and tight. Mastering how to check solenoid on golf cart empowers you to troubleshoot effectively, saving time and potentially costly repairs by accurately identifying this common failure point in your cart’s electrical system.
