Yesterday my spot lock and autopilot buttons wouldn't work (so both on the right side of the pedal). No beep no light, nothing. Everything else worked fine. Took off the plate and fiddled around with the board which might have been a little loose and they started working. Judging by the screws I'd say this board has been previously replaced (bought the motor used).
Would adding a lock washer on the two screws that hold the board to the plate help keep it in place if it was loose?
OR
Is this an indication (if it wasn't loose, again I really don't know I just took stuff apart) that the board is going bad?
