My 763 G will do nothing but say INPUT on the hour display when you turn the key on. I checked with dealer and they said it was either the left or right hand panels. I replaced both with new ones but it still does the same thing. My service manual says that the code INPUT means that the Bobcat controller is not communicating with the left hand panel. I have checked wires and pin connectors but nothing jumps out at me. Has anyone encountered this before? Any info is appreciated.
