With voltmeter, I have it wired properly I hope. My 12V is yellow always hot. I used an aftermarket pigtail that is all black. I need to know order. I bought a new alternator from LMR and have had a totally dead battery 2x this week. If I wired them opposite, would I know? It could be a faulty alternator, a bad battery, or a parasitic draw. I hunted down and removed an old alarm system I found on the car today. We'll see what happens. I'd still like someone to check the order on their connection visually to confirm for me.
