what is the cause of a golf cart motor putting voltage to the case

by Jovanny Farrell DDS Published 2 years ago Updated 1 year ago

If there is voltage present and the pack reads the combined voltage necessary (36v or 48v) but no sound from the solenoid, it is time to really dig into the electrics. This could be a faulty solenoid or a problem with the pedal potentiometer and any of the wiring in between. Check out this guide to troubleshooting solenoids.
