Won't start or move

A golf buggy that will not start or will not move is the single most reported electric drive fault, and in most cases the cause sits in a short list: the battery pack, the Tow/Run switch, the key switch, a fuse, the solenoid, or the controller. The guides in this category work through that list in order, covering buggies that power up but refuse to drive, solenoids that click without movement or stay silent, vehicles that cut out on the move, and finding and testing fuses. Two checks resolve a large share of cases before any tools come out. First, confirm the Tow/Run switch is in Run; in Tow the drive system is deliberately disabled. Second, measure the rested pack voltage: a 48 volt lead-acid pack close to 50.9 volts is full, while a pack below roughly 48.5 volts is significantly discharged and may be too low for the controller to operate. Then listen at the pedal. A clear click from the solenoid with no drive points towards its main contacts or the circuit beyond it; when a solenoid is working properly, the voltage measured across its two large studs falls to close to zero as the contacts close. One fault deserves separate mention. A buggy that lurches into drive the moment the key turns has a solenoid welded on, which is a safety-critical condition: switch off, put the vehicle in Tow, stop using it and book a Hawke engineer.
