Cart surges but wont move

Hey guys I have somewhat of an odd problem.

I have a Melex 512E (1995) which I understand is nealry an EZ GO clone. So I'm hoping someone can help me here.

The cart has newer Trojan batteries all holding at the proper voltage.

It uses a Curtis 1204 controller.

I'm somewhat stumped to what the actual cause of my problem. With the key on and a direction selected, when I depress the go pedal it will surge in the selected direction but not move. After this I cannot get the cart to respond to any input unless I cycle the key off and the direction selector to neutral and then back to either forward or reverse.

While troubleshooting the controller and checking the controllers output from (B+ to M-), I've got zero voltage with the pedal up and with the pedal down my voltmeter surges momentarily and then returns to zero. The voltage surge is minimal maybe 5-10 volts.

Does anyone know what would cause this?

Any assistance provided will be appreciated.

Welcome to the forum...

Try jumping the two large posts on the solenoid and see if it moves. Check all your cable connections. If that doesn't work you may have a bad controller.
