A ballast resistor was not used/needed on a GM 6v system (positive or negative ground).
Thank you. Do you think someone tried using a 12v battery and did some trickery? It's one of those things that when you see someone rattle can the entire firewall, and everything mounted to it, regulator, all the wires are now black, I start thinking that other things were half-assed. Now after seeing that 12v battery in the photo I need to ignore anything I've heard from the PO.
