Power drainage

[Caddylover]

I recently replaced the alternator in my 93 Cadillac deville, and since then I’ve been having problems with the car dying/not starting. Brought it back and the mechanic replaced the alternator, but the car would still die. He replaced the battery and the same thing happened. He replaced that battery, but the car would still die.

It’s weird because when I put my jumper on, it fires up and stays charged while I drive it around town, but if I turn it off without driving it a long time, it won’t start again. I recently jumped it and drove it around for a half hour without the stereo on and it would start up again after I shut it off. But if I let it sit a couple days, it won’t start. What gives?

Parasitic drain.

Good luck..

I’m hoping it’s something simpler, like a bad starter or something like that....

Kill switch wouldn’t hurt.. it doesn’t fix the issue of from where but gives you peace of mind

How is this related to car audio?

audio/accessory power circuit is the cause of a parasitic drain more often than not. There’s really no help to be had he just has to track it down
