If it is a gas-powered cart, the engine doesn’t turn over, and if it is an electric cart, the cart doesn’t move. 2 The engine on the gas-powered cart starts, but the starter doesn’t disengage after starting. When the contacts weld together, the power to the starter never stops and will result in destroying the starter, the wiring, or the flywheel. 3 The relay clicks and works sometimes, and sometimes it doesn’t. This can be a faulty wire connection, but can also mean the solenoid is beginning to fail. 4 The golf cart solenoid doesn’t click when the accelerator is pressed. This again can be faulty wiring or a failed solenoid. 5 The golf cart solenoid clicks, but nothing happens. This will sometimes be the result of burned contacts or contacts no longer coming in contact with each other as shown in the illustration at the bottom of this page. This can also be the result of not enough voltage amps reaching the solenoid control connection due to a low battery.
