  2. Disconnect the Battery: Ensure that the power to the golf cart is turned off and the battery is disconnected to prevent accidental shocks.
  3. Measure Resistance: Place the multimeter probes on the solenoid terminals. A functional solenoid typically shows a resistance reading between 0.5 to 2 ohms. If the reading is significantly higher or shows infinite resistance, the solenoid is likely faulty.
Resistance Reading Status
0.5 – 2 ohms Functional
Higher than 2 ohms Possibly Faulty
Infinite Faulty

Applying Direct Voltage

Another method to check the solenoid’s operation is to apply direct voltage. This process involves:

  1. Reconnect the Battery: Ensure that the battery is connected and the golf cart is in a safe state.
  2. Use Jumper Wires: Connect two jumper wires to the solenoid terminals.
  3. Apply Voltage: Connect the other ends of the jumper wires to a power source (typically the battery). This should energize the solenoid, causing a clicking sound if it is functioning properly.

Be cautious during this procedure to avoid short circuits or electric shocks.

Testing the Solenoid in the Circuit

If the solenoid appears functional when tested individually, it is prudent to check its operation within the golf cart’s circuit. Follow these steps:

  1. Turn on the Golf Cart: Ensure the ignition is on to allow electrical flow.
  2. Listen for Activation: Depress the accelerator pedal and listen for the solenoid engaging. A distinct click should indicate it is working.

Using a multimeter is an effective way to test the functionality of the solenoid. Follow these steps:

  1. Safety First: Disconnect the battery to prevent any electrical shock.
  2. Set Up the Multimeter: Adjust the multimeter to the ohm setting (Ω).
  3. Measure Resistance:
  • Connect the multimeter probes to the two large terminals on the solenoid.
  • A reading of zero or near zero indicates a short, while infinite resistance indicates a fault.
  1. Test the Coil:
  • Connect the probes to the two small terminals on the solenoid.
  • A typical reading should be between 3 to 5 ohms for a functional solenoid.

Checking the Activation of the Solenoid

To confirm that the solenoid is activating properly, perform the following test:

  1. Reconnect the battery.
  2. Use a jumper wire to connect the positive terminal of the battery to one of the small terminals on the solenoid.
  3. Touch the other small terminal to the negative terminal of the battery.
  4. Listen for a click sound, which indicates that the solenoid is engaging.

Evaluating Voltage at the Solenoid

If the solenoid does not activate, you may need to check for voltage:

  • Set your multimeter to the DC voltage setting.
  • Turn on the golf cart and measure the voltage at the small terminals of the solenoid.
  • A proper reading should be around 12 volts when the accelerator is pressed. If no voltage is detected, check the wiring and switches leading to the solenoid.

Troubleshooting Common Issues

If the solenoid fails any of the above tests, consider the following troubleshooting tips:

Issue Possible Causes Recommended Action
No click sound Faulty solenoid or poor connections Replace solenoid or repair connections
Solenoid clicks but cart does not move Faulty controller or motor Inspect and test the controller and motor
Inconsistent operation Corroded terminals or weak battery Clean terminals and check battery health

Replacing the Solenoid

If the solenoid is found to be defective, replacement is straightforward:

  1. Disconnect the battery.
  2. Remove the old solenoid from its mounting position.
  3. Disconnect the wires from the terminals, noting their positions.
  4. Install the new solenoid by reversing the removal steps, ensuring all connections are secure.
  5. Reconnect the battery and test the golf cart to ensure proper function.

By following these steps, you can effectively check and diagnose issues with the solenoid in your golf cart, ensuring reliable operation.

Hi, I’m Joseph Benedetto, the founder of Cincy Sports Nation. If there’s one thing that sports have taught me over the years, it’s that the field can teach you just as much about life as any classroom. Back in 2017, when the opportunity came to breathe new life into an old tire distribution center in Milford, Ohio, I knew it had the potential to become something more than just another building. I wanted to create a space where players of all ages could come together to train, to compete, to connect and that’s exactly how Cincy Sports Nation began.

It quickly became clear, though, that the real magic wasn’t just in the games themselves. It was in the moments between them the coaching advice passed down after practice, the skills quietly honed, the lessons that athletes carried with them long after they left the field.

This isn’t a collection of theories or textbook strategies. It’s built from real hours spent running drills, adjusting techniques, and learning lessons the hard way. At Cincy Sports Nation, our goal is simple: to pass on that knowledge in a way that’s honest, accessible, and built for anyone who’s serious about getting better, no matter their starting point.

Thanks for being part of this journey. Even though the setting has changed, the mission remains the same helping athletes grow smarter, stronger, and more passionate about the games they play.
