Default 2005 Club Car Won't Go

Hello, I have stock Club Car S/N AQ0515-493566 that is driving me crazy. When I press on the go pedal all the way down I hear the mcor microswitch click, but the car will sit there for up to a minute, then I hear the solenoid click, but no movement. I keep the pedal pressed down and wait 15 to 60 seconds or so and hear the solenoid click again, sometimes the wheels will just turn a few inches, then nothing. Keeping the pedal down, wait another minute and the car might spin the tires a few seconds, then nothing.

With full charge and clean cables I have 52.48v, and I perform good regular maintenance on the batteries. I've tried jumpering the solenoid with no change (same symptoms). I bought a new solenoid last year and put it in, still had these same symptoms. But last year if I kept the pedal pressed the car would eventually take off and move. It might take up to five minutes of sitting there, but eventually it took off and would often behave fine for a while. While it was moving never a problem, but when you stopped and went to start again, it had a 50% chance of moving again immediately, or sitting there for a while before it decided to take off!

That was last year, but now it seems worse. Any suggestions would be greatly appreciated.

Thanks Shadowman, I have a diagnostic procedure to check out the mcor and will report back once I perform the check.

On another note, is there anyway to prevent sparking when I attach the #6 battery negative cable? I have the cart in neutral and on 'tow' but still get a good pop when I re-attach the cable. Doesn't spark when I take it off.

Reguarding the spark, Do you have any accesories attached to that negative post or just the one cable?

Is there a voltage reducer in cart for lights? If so, that can cause the spark when reconnecting battery pack which would be considered normal . . .

Nothing else connected to the last battery except the cable going to B-. Cart has lights and I thought that the yellow wire with 20A fuse off battery 5 was supplying 12v to run lights.

I definitely don't like that spark right by potentially explosive batteries!

I jumpered the blue and green wires going to the mcor and the car ran. I still have a problem where the car will have the solenoid 'drop out' when going, but if I change the pedal position the car will re-engage the solenoid and keep running. So, looks like the inside of the mcor isn't allowing good contact and I will be replacing that soon.

Thanks and a big shout out to all who helped me get this car running again (wife's happy)!

I think you've narrowed your problem down to the MCOR, as for the sparking, try unplugging the TOW switch completely from the wire harness and see if it sparks. I've seen them short internally and cause arcing like you speak of. If it makes the sparking stop, replace the tow switch. If it doesn't, let me know.
