I'm trying to sort it with y'alls help. So far I have removed the resistor & wire and a another wire from the ammeter to the ign sw. I have a new ammeter not installed, old one had terminal insulators melted so posts touched the case.
Does anyone have elec diagram for a 12v conversion.? if I had that I would change out that rats nest of red wires on the firewall, one wire at a time.
