I was just given a 2004 Club Car Precident by my brother. It doesn’t move at all. He said it was fine and he charged it and left it for a few months at his camp. When he got back it would not move. The batteries are good and test at 50volts and the charger works just fine. The key switch is good and he put in a new mcor but that did not help. I tried to test the OBC with a multi meter. When I connect meter between light blue wire from 6 wire connecter and negative on battery as manual says, I only get about 25 volts. I get the same with the red wire. When I use meter probes to jump between blue and red at connector on harness side I get 50 volts. Is this an indication of a bad obc or do I need to look elsewhere. Any suggestions would be appreciated. I don’t want to spend big bucks on a new OBC and then find out that was not the problem. Thanks in advance.
