Golf Cart Won’t Move? What to Check Before You Start Buying Parts
Key on, pedal down, absolutely nothing. Before ordering a controller, motor and three other expensive parts, slow the parts cannon down and collect clues.
Start with the embarrassingly simple stuff
Confirm the pack is charged, the run/tow switch is in the proper position where equipped, the direction selector is working and required safety interlocks are satisfied. Look for loose cables, overheated terminals, corrosion and damaged connectors.
Listen to what the cart is telling you
Does the main contactor click? Does the display stay alive when the pedal is pressed? Do the lights dim hard under load? Does the cart move in one direction but not the other? Each symptom narrows the list of suspects.
Resting voltage is only the beginning
A battery pack can look healthy sitting still and collapse when asked to deliver current. This is especially common with aging lead acid batteries. Good diagnosis includes what voltage does under load, not just a pretty number with the cart parked.
Control side versus power side
The key switch, pedal switch, direction input, safety circuits and controller enable circuit tell the cart when to move. The battery, contactor, controller and motor provide the power. Knowing which side failed prevents expensive guessing.
Do not turn a diagnostic bypass into a repair
A trained technician may temporarily bypass a circuit during controlled diagnosis. Permanently defeating seat switches, interlocks or other safety devices is not a proper fix. Find the failed component and repair the circuit correctly.
