MinnKota foot pedal schematic

[The--Captain]

I've recently come across a rather ancient Minn Kota Powerdrive bow-mount troller - my buddy warned me that the foot pedal was probably shot (in fact he told me that was the reason the troller was discarded)... Since the foot pedal cable was well frayed and cracked, I cut and stripped it to make test connections (knowing I would have to at least try to restore some waterproofing to it later) and disassembled the foot pedal. My multi-tester indicates that almost all of the sealed circuit-mounted micro-switches are corroded (I guess they're not sealed all that well). I can deal with the corroded switches - even if the foot pedal is a wash (which is very likely), I can always install some custom controls on the dash of the boat (hey, it's a bow-mount - it's not like I'm going to be moving it between boats like a transom troller anyway).

So, this brings me to my question - the only part in the foot pedal that is not an actual on/off switch is the speed control, hence my request for a schematic - the existing pedal speed control certainly registers varied resistance, but I'm not sure how much of the resistance I should attribute to corrosion, and how much is built in to the potentiometer - a schematic should give me a rating for the potentiometer that governs the speed controller.. .

I'd make a joke about how this piece of information is like a wily lunker, evading capture, but I'm sure that gets old around here real quick ;-)

Any and all comments are welcome and appreciated.

Cheers,
