One wire GM style alternator wiring help needed.

Mike69cuda said
For cars that sit a lot, a GM one wire alternator will drain the battery in about a month. They pull about 75 micro amps all the time. Doesn’t sound like much, but it is enough to drain a battery over a period of time. Found this out on my boat with a chevy engine. A cutoff switch would help this, or you could just disconnect the battery when not driving foe awhile.

I put a kill switch on the battery. I drilled a hole on the reverse light so not to mess up the car with a hole through the body. The wheel house had a tab on it with a hole. It was a perfect spot for the ground wire
