If it runs with the jumper I'd say the controller is bad.Don't let the cart run at full speed with the rear tires off the ground..

UPDATE!!!! I got it to move again. Looks like the controller is crapping out on us. If you bang on it a few times, it will run. Until you stop!

Is there a way to "clean" the controller? I already cleaned all the connectors.
