How to test a MCOR II with a meter

[woodit]

I have a 2009 48v Precendent, at the end of last year the cart would die, like someone stepped on the brakes when floored. If I let off the pedal it would go and stop abruptly, now it wont move. when I switch it to reverse the buzzer sounds but doesnt move. I have 49.5 volts. When I press on the gas pedal I hear a click at the pedal but I dont hear the solinoid pull in. There are 5 wires coming out of the MCOR II which ones do I test and what resistent should I have? I have 0 volts across the solinoid, 48.2 volts to ground on one side and 49.2 volts to the other side. I searched for a wiring diagram and trouble shooting steps for this cart but only found stuff for different carts, any help would be helpful, Thanks
