I have recently rebuilt a 91 ezgo marathon. I upgraded the wiring, new batteries, new EMP motor. It was running but the 2 speed motor was intermittant and the key didn't work, I just hit the pedal and it would go. Now i get nothing and the solenoid doesn't click. I'm looking for any help, ihave been over the wiring multiple times and feel confident that is correct, so now I'm open for suggestions.
