Hello Dougmcp ,Thanks for the diagram, its the same basic set up with a few minor differences noted at the solenoid so far. This diagram shows a red from the pedal to the left side of the coil solenoid with a yellow wire, which makes sense. Mine has one yellow wire. I traced the dead 36v key switch wire(white yellow trace) to the controller. The fnr swtch has no power but does have continuity. On the other end the reed switch wire has power and the micro switch has continuity and power. The on thing thats left is the tow switch, and what are odds on that? I tested with a digital vom and had to crank it to 200m before I got some numbers on it.
