I own a 1986 1100 and I don’t have any battery power anywhere. Even turning the key to on, no lights turn on, literally nothing.
I started with with the Starter Relay by jumping the red and black wires, starter turns over. That lead me to the yellow/green wire and the black/white wire I checked the continuity of the ground wire to the battery ground, it was good. I wasn’t getting power to the yellow somehow. Followed the wiring diagram to the engine stop switch, it was good. Continued to the Ignitor, and I’m not sure what is going on. I believe it’s bad, but I can’t confirm at all.
