no f/r

My screen name is a bit misleading. I don't golf, so all I am here for is repairs. I don't typically work on golf carts. Anyway, I am working on a Melex 212 36V for a buddy. -It has two new batteries and the other four tested good. The batteries are wired as per the resistor wiring schematic...

1995 Club Car DS 48v has been working for years. Pulled into the garage, put it on charge which completed just fine. Will not move in F/R. Pack is 3yrs old and at 51v. I hear the GO pedal click, then the solenoid click in both F and R. No intermittent issues or problems leaf up to this...
