Hi, I just purchased a used 2006 Yamaha G22E cart, the person I purchased it from said he installed new batteries at the end of the season and parked it. I've tested the batteries and they are good, there was no power through the solenoid by the controller (turned out to be a 24 v rated solenoid), I ordered the correct 48 V one from Yamaha, I now have 48 v through the solenoid to the controller but the cart still does not move. When put in reverse the back up buzzer works but no movement. Wondering if the controller and/or motor is dead? Any suggestions?
