Charging system

If you are talking about the light blue field power wire, that is fed by the IGN1 ignition power feed coming off the ignition switch, "IGN1" coming through the bulkhead, and branching off to feed the field, the VR IGN terminal, the ballast resistor for the ignition, and depending on year/ model, some smog doo dads, etc

There is ONLY ONE "switched" power feed into the engine bay, and that is it. Voltage drop in this circuit often causes OVER chargeing because if feeds UNDER voltage to the VR, "which thinks" the battery is low.


One way to work around this, is to electrically cut the IGN1 wire coming out of the bulkhead, feed the bulkhead end to trigger a Bosch relay, feed the relay contacts power off the start relay, and take the switched load out of the relay and connect that to the other end of the cut wire
