SOURCE: Minn Kota power drive trolling motor will not

It is the circuit board in the foot pedal. You will have to replace the whole foot pedal. This is a very poor design. The thin plastic which protects the contacts gets a little hole which allows water to enter and consequently the contacts corrode. Has happened to me two times in past four years. It might be OK for operation in a dirt-free water-free environment; but not under actual fishing conditions.
