If you own a golf cart, you know how important it is to keep it in good condition. One of the essential components of a golf cart is the solenoid.

The solenoid is responsible for delivering power to the cart’s starter motor, and if it’s not functioning correctly, your golf cart won’t run.

That’s why it’s crucial to know how to test a golf cart solenoid. In this section, we will provide you with step-by-step instructions to troubleshoot and diagnose solenoid problems in your golf cart.

Key Takeaways

  • Understanding the role of the solenoid in your golf cart is crucial to troubleshoot issues properly.
  • The necessary tools for solenoid testing include a voltmeter, a test light, and a basic multimeter.
  • Following a step-by-step guide can make the testing process smoother and more productive.
  • Troubleshooting common solenoid problems can help identify specific issues and determine appropriate solutions.
  • Regular maintenance and timely troubleshooting will keep your golf cart running smoothly on the green.

What is the Golf Cart Solenoid

Before learning how to test a golf cart solenoid, it’s important to understand its role in your golf cart. The solenoid is a crucial part of the golf cart’s electrical system that controls the flow of power from the battery to the motor.

When you press down on the accelerator pedal, the solenoid connects the battery to the motor, allowing the cart to move. When you release the pedal, the solenoid disconnects the battery from the motor, causing the cart to stop.

Common issues with solenoids include failure to connect or disconnect the battery, resulting in the golf cart not moving or stopping abruptly. Electrical problems such as loose connections, corroded terminals, or damaged wiring can also affect solenoids.

Common Golf Cart Solenoid Problems

Here are some common solenoid problems you may encounter:

  • The solenoid clicks but the cart doesn’t move
  • The solenoid fails to click and the cart doesn’t move
  • The solenoid clicks and the cart moves, but it moves slowly
  • The solenoid clicks constantly, even when the cart is not in use

If you notice any of these problems, it’s important to troubleshoot and diagnose the issue as soon as possible to avoid further damage to your golf cart.

Tools Needed for Solenoid Testing

Testing a golf cart solenoid requires specific tools to ensure accuracy and efficiency. Here are the essential tools you’ll need to have before you begin testing:

MultimeterA digital multimeter is used to measure electrical voltage and current. Make sure it’s set to measure DC volts.
Wrench setYou’ll need an adjustable wrench to remove bolts and nuts from the solenoid.
Insulated pliersThese are used to remove wires from the solenoid without getting shocked.
Battery chargerYou’ll need a battery charger to power the golf cart during testing.

Apart from these tools, it’s also recommended to have a golf cart service manual and safety glasses on hand. The manual will provide additional guidance on solenoid testing and the safety glasses will protect your eyes from harmful debris.

Step-by-Step Guide to Testing a Golf Cart Solenoid

Now that you have a solid understanding of the role of the solenoid in your golf cart and the necessary tools, it’s time to start the testing process.

Step 1: Preparation

Before testing the solenoid, make sure the golf cart is in neutral and the key is turned off. Then, disconnect the negative battery cable to avoid electrical shock and remove the wires connected to the solenoid.

Step 2: Testing the Solenoid Coil

Using a multimeter, set it to the ohm range and place one meter lead to the small terminal on the solenoid and the other to the solenoid’s metal case. If the meter reads no resistance, the solenoid coil is faulty and needs to be replaced.

Step 3: Testing the Solenoid Contacts

Connect the multimeter to the large terminals on the solenoid. Turn the key on and press the accelerator pedal. The meter should read 36 volts or the voltage of your golf cart battery. If there is no reading, the solenoid contacts are faulty and need to be replaced.

Step 4: Interpreting the Results

If both the solenoid coil and contacts have passed the tests, it’s likely that the problem lies elsewhere in the golf cart’s electrical system. However, if one or both have failed, you can replace the solenoid or contact to fix the issue.

Remember that regular maintenance and troubleshooting can prevent further issues with your golf cart’s solenoid. By following these steps and utilizing the proper tools, you can easily diagnose and fix solenoid problems on your own.

Troubleshooting Common Solenoid Problems

Solenoid problems can be frustrating to deal with, but understanding common issues and their solutions can help you diagnose and fix them quickly. Here are some troubleshooting tips for common golf cart solenoid problems:

Problem: No Power

If you notice that your golf cart is not getting any power, the first thing you should do is check the batteries. Low battery voltage is a common cause of solenoid failure. Make sure your batteries are fully charged and functioning properly.

Problem: Clicking Sound

If your solenoid is making a clicking sound when you turn on the ignition, but the golf cart doesn’t start, you may have a defective solenoid or a bad connection. Check the connections to make sure they are clean and tight. If everything is properly connected, you may need to replace the solenoid.

Problem: Stuck Solenoid

If your solenoid is stuck in the on or off position, it means that the contacts are welded together or stuck apart. This can be caused by arcing, which can damage the contacts over time. The only solution is to replace the solenoid.

Problem: Overheating

If your solenoid is overheating, it may be due to excessive current flow or a dirty or worn-out contact. Check the cables and connections to ensure they are not damaged or corroded. If everything looks good, you may need to replace the solenoid.

By understanding these common solenoid problems and their solutions, you can troubleshoot your golf cart solenoid with confidence. If you are unsure about how to proceed with any troubleshooting, consult a professional or refer to the manufacturer’s manual for guidance.

Additional Tips for Solenoid Testing

Testing a golf cart solenoid can sometimes be tricky, but with the right approach and tools, you can troubleshoot and diagnose issues with ease. Here are some additional tips and best practices to keep in mind:

  • Always have a fully charged battery before testing the solenoid. Low battery voltage can cause inaccurate test results.
  • Use a voltmeter to check the voltage across the solenoid terminals and ensure that it’s not reading zero or too low. If it is, there may be a problem with the solenoid coil or internal contacts.
  • Wear protective gloves and goggles when testing the solenoid to avoid any injuries or accidents.
  • Refer to the manufacturer’s manual for specific instructions on testing the solenoid. Different golf cart models may require different testing methods.
  • Regularly inspect and maintain the solenoid, including cleaning any dirt or debris buildup and checking for any signs of wear or damage.
  • If you’re unsure about any of the testing procedures or results, seek the help of a professional technician or mechanic.

“By following these additional tips, you’ll be well-equipped to tackle any solenoid issues that may arise in your golf cart.”


Congratulations! By following this guide, you now have the knowledge and tools to test and troubleshoot your golf cart solenoid successfully. Remember to conduct regular maintenance checks on your cart and address solenoid issues promptly to avoid further damage and unnecessary repair costs.

If you encounter any problems during the testing process, refer back to this guide, or seek professional help. Remember to stay safe and follow all safety precautions when working with the electrical components of your golf cart.

Keep Your Golf Cart Running Smoothly

Regular maintenance and timely troubleshooting are essential to ensure the proper functioning of your golf cart. By keeping your solenoid and other electrical components in top condition, you can enjoy a smooth and reliable ride on the green for years to come.
