How to test controller on 94 ezgo electric golf cart?

To test the controller on a 94 EZGO electric golf cart, you can follow these steps: 1. Start by disconnecting the battery cables to ensure safety while performing the test. 2. Locate the controller, which is usually located under the seat or in the front storage compartment of the golf cart. 3. Inspect the controller for any visible damage or loose connections. Make sure all cables are securely connected. 4. Check the controller's input voltage by using a multimeter. Connect the positive lead of the multimeter to the positive terminal of the controller and the negative lead to the negative terminal. 5. Turn on the ignition on the golf cart and observe the voltage reading on the multimeter. It should match the battery voltage (usually 36 volts for a 94 EZGO golf cart). 6. Test the output voltage of the controller by connecting the positive lead of the multimeter to the throttle input terminal and the negative lead to the negative terminal. 7. With the ignition on, operate the throttle pedal and observe the voltage reading on the multimeter. The voltage should increase smoothly as you press the throttle. 8. If the controller fails any of these tests, it is likely faulty and needs to be replaced. However, if the controller passes the tests but you are still experiencing issues with your golf cart, it is recommended to consult a professional technician for further diagnosis. Remember to always exercise caution and follow safety guidelines when working on electrical components of a golf cart. If you are unsure or uncomfortable with performing the tests yourself, it is best to seek assistance from a qualified technician.
