Columbia ParCar won't

[dave377]

I have a 36 volt that belongs to a friend and he was driving it and it quit. It won't do anything when pushing the throttle in forward or reverse. I checked the battery voltage and it has 37.5 volts I tested the relays and they check good off the cart but will not click when on the cart. I checked the resistance on pot switch and it seam to be working. There is a micro switch on the pot and it is not working I think it go to back up beeper. Where should I go next.
