The only connector I checked was the 4 pin that goes to the PCB, I only checked the red and black wires, that's where I get whatever voltage I put in up to 20 volts (red goes to on, off smoke switch, of coarse black to ground one white wire goes to a cherry switch and the other white wire goes to the AC regulator).
Well I have that AC regulator #691ACRG103, I purchased everything I could for that engine, I hope it's not to bad to put in, I'm 71 yrs. young and I have essential tremors, (the shakes) makes it very hard for me to solder.
