Controllers and electrics

Everything between the pedal and the motor on an electric golf cart lives in this category: the speed controller, throttle input sensors such as the Club Car MCOR and the E-Z-GO inductive throttle sensor, jerky or delayed acceleration, controller failure and overheating, limp mode, brand reset procedures, battery meters that read wrongly, and alarms that sound while driving. Odd behavior in this chain often has a plain cause. Before condemning a sensor or the controller, clean and tighten the main battery connections, because a loose or corroded terminal produces the same surging and cutting out that a failing part does. A worn throttle sensor tends to show as a scratchy, inconsistent signal, and a multimeter at the input wiring will narrow a repeatable fault on many vehicles. Some controller families report their own trouble: Curtis controllers flash a status light in a repeating pattern that identifies the fault, and limp mode, which holds the cart to walking pace, is a protection state the controller enters deliberately rather than a breakdown. The controller itself deserves respect. Its capacitors can hold a charge after the pack is disconnected, and the main B plus and B minus terminals carry full pack current, so wait several minutes after disconnecting and keep tools clear of the studs. Connection checks, sensor cleaning and resets suit an owner. For controller replacement, precharge faults or any burning smell, send us the details through our support request form.
