I fixed the control cables that were crimped. After removing the chair (4 nuts, power cord tie wraps, seat rotating cable lock), I jumpered a 9 volt battery to the motor which powers the forward/reverser gear boxes, and moved the seat forward enough to allow the cable wrap to be moved back to the center of the frame.
One cable had been crimped enough to pierce the wire insulation, causing the circuit breaker to trip. It was not cut, so i taped it up.
I checked the drivers chair, and the control cable wrap is not tied to any component, but it was positioned between the chair cushion and the square frame that holds all the motors. I believe the one on the passenger was not positioned properly.
All works well now.
Blue wire was 9volt positive, and moved chair forward.
