In the process of replacing burned wires from a meltdown, I inadvertently forgot to take notes on the wire going from the "IG" connection on the voltage regulator to the ignition switch. Unfortunately electrical diagrams I've seen don't show that connection path. I'm pretty sure it was connected to the "B" connection on my ignition switch below. That black wire in the photo on the "B" connection was the main wire that melted. The wire that goes to the voltage regulator suffered collateral damage and was piggy backed with another wire on the switch. Does that sound right?
