Did you check the alternator output? If voltage is too high, all systems will stop.

Have you checked the indicator lights on the controller under the seat? Red light means failed controller.

Is the monitor still out? Long shot on this one, disconnect the pump pressure sensor. I have seen one short and cause the monitor to short out.

Did the backup switches work? They are located in the rear of the right console.

Please include the machine serial number with your reply.
