G.E. electric motor help

Sounds like the controller's throttle input circuit is screwed up, but without a schematic it is going to be a poke and hope process.

Personally, I'd replace the controller.

In the curtis 1204 manual there is a diagnostic step that has a voltage check by backprobing the throttle pot terminals at the controller. This will give You a confirmation of a board problem.

I have a bad controller here that failed that voltage check. I took it apart anyway just to see if I could without breaking anything.

I have the schematic and there is no question that the controller is bad at this point. I was just hoping to fix it on the cheap. I have way too many bad habits and one working cart to put any money in this cart.

Do you still have this bad controller? I took my controller apart again and removed the A2 bar and the plug diodes just to see if I could make it work, sadly it didn't. My throttle pot responds properly to the input, the controller just doesn't put anything out to make the motor move. I have been unsuccessful at finding a circuit board schematic for the Curtis controllers.
