Hey guys. Hoping someone can shed some light on this issue I'm having. So the battery in my 1970 coupe Deville keeps dying. I change the alternator but still keeps doing it. It's like it stays in all the time even when the key is off. I can still operate the power windows and stuff. When the car is running I removed the positive off the battery and the car shuts off. Usually it's a sign of a bad alternator but that's new. I'm confused
