How to troubleshoot a Club Car controller?

A problem in the controller means you are facing trouble starting your cart. Well, this can happen for some other reasons as well. That is why it essential that you speculate every other part of the cart before you start checking the controller.

Sometimes the golf cart battery can go dead if you keep the cart in hibernation for a long time. Besides, using a battery for more than 3 years can reduce the power to a great level. Poor battery maintenance can also cause the battery to go dead without giving any proper signal.

Find a battery tester and check whether the battery has power or not. A dead battery will not transmit the exact current or voltage even if the controller is okay.

Step two: charge the battery and try again.

If you have a dead or low-charged battery, plug in the battery charger to give it some energy. Now try again starting the engine of the cart.

If that solves the problem, you don’t need to worry about the controller. Everything is okay with the controller.

If you are not sure whether you have got a good or bad solenoid, here are some of the ways to test the solenoid-

  1. First of all, you will require some accessories to do the testing. Gather a voltmeter, wrench, electrical tape, safety equipment before getting into the process.
  2. Turn off your golf cart and remove all the cables attached to the solenoid terminals.
  3. In the next step, you have to check each and every terminal with the help of the voltmeter.
  4. If you are using an electric golf cart, check the solenoid by turning on the ignition. If the voltage jumps or shows an exceeding level on the voltmeter, the solenoid should be the problem.
  5. In case you have a gas-powered golf cart, you need to look for the clicking sound. If you get a higher reading on the voltmeter, there must be something wrong with the solenoid.
  6. A deteriorated solenoid will always create problems even if the controller has no complications. Think about replacing the solenoid in case you find any problem with it.

Step four: fixing the controller

If nothing is wrong with the previous three steps, it should be the problem with the speed controller. Every Club Car golf cart controller delivers a signal, disclosing the reason for the problem. 

A popping light will deliver a morse code specifying the exact reason for the problem. If anything is wrong with the voltage level, you need to go back to the battery or solenoid section again to check the connection.

On the other hand, you need to think about a replacement if the code specifies that the problem is with the controller. You cannot expect a smooth performance from a faulty or deteriorated Club Car controller.
