How to Test a Golf Cart Solenoid

A golf cart solenoid is an electrically operated switch that is responsible for controlling the flow of electricity between the battery and the motor. It serves as an essential component in the operation of the golf cart.

Importance of testing a golf cart solenoid:

Testing a golf cart solenoid is crucial to ensure that it is functioning correctly. A malfunctioning solenoid can cause several problems , such as power loss, reduced performance, or complete failure. Therefore, testing a golf cart solenoid regularly can help prevent these issues and prolong the life of the golf cart.

Tools and Materials Required:

A. List of tools:

  1. Multimeter
  2. Wrench
  3. Screwdriver
  4. Wire stripper

B. List of materials:

  1. Safety glasses
  2. Gloves
  3. Battery terminal cleaner
  4. Cleaning rag


Types of golf cart solenoids: There are two types of golf cart solenoids: 36-volt and 48-volt solenoids. The type of solenoid your golf cart needs depends on the voltage of the battery pack. It is essential to purchase the correct type of solenoid to ensure compatibility with your golf cart.

Importance of testing voltage: Testing the voltage across the solenoid while it is in operation is crucial to determine if the solenoid is functioning correctly. If the voltage fluctuates as you activate the solenoid, it indicates that the solenoid is not transferring the electrical current efficiently. This could lead to a loss of power or performance issues with the golf cart.

Testing the solenoid with a battery load tester: In addition to using a multimeter to test the solenoid’s continuity, you can also use a battery load tester. A battery load tester applies a load to the battery and measures the voltage drop. If the voltage drop is significant, it indicates that the battery is weak and needs to be replaced. This test can help determine if the battery is causing any issues with the solenoid.

Replacing a faulty solenoid: If the solenoid fails any of the tests, it needs to be replaced. To replace a faulty solenoid, you will need to remove the old solenoid and install a new one. Make sure to follow the manufacturer’s instructions carefully and reattach all wires and connections securely.

Maintenance tips: To maintain the proper functioning of the solenoid and prolong its life, you should keep the connections clean and tight. Use a battery terminal cleaner to remove any corrosion on the battery terminals and solenoid connections. Additionally, keep the solenoid free of debris and avoid overloading the golf cart, which can cause excessive wear on the solenoid.

Testing Procedure:


  1. Disconnecting the battery: Before testing the solenoid, it is necessary to disconnect the battery to prevent any accidental electrical shock or damage to the golf cart.
  2. Safety precautions: Wear safety glasses and gloves to protect yourself from any hazards.

Testing the solenoid:

  1. Visual inspection: Inspect the solenoid for any physical damage or corrosion. Look for signs of melted plastic, rust, or loose connections.
  2. Testing continuity: Using a multimeter, test the continuity of the solenoid by checking the resistance between the two terminals of the solenoid.
  3. Testing voltage: Test the voltage across the solenoid while it is in operation. Check if the voltage fluctuates as you activate the solenoid.

Analyzing the test results:

  1. Normal test results: If the solenoid passes all three tests, it is working correctly.
  2. Abnormal test results: If the solenoid fails any of the three tests, it is malfunctioning and needs to be replaced.


A. Common solenoid problems:

Some common problems associated with a faulty solenoid include:

  1. Clicking sound
  2. No power to the motor
  3. Slow acceleration
  4. Overheating

B. Solutions to common problems:

  1. Clicking sound: Check the battery and connections for any damage.
  2. No power to the motor: Check the connections to the motor and the solenoid for any loose connections or corrosion.
  3. Slow acceleration: Check the battery charge and replace if necessary.
  4. Overheating: Check the solenoid for any physical damage or corrosion.
