Quick sketch of the circuitry involved in wiring the starter motor on most motorcycles or cafe racers.


One of my spring projects is to re-wire my wife's old Yamaha. I figure I'll just scrap the stock wiring and run my own.

This is a circuit of my own creation. I sketched it mostly as a way to think out loud regarding the wiring of the bike's starter motor. I wired it 70's-style, with a common ground (the frame of the bike) and only positive DC current carried through the wires themselves.
