2000 cadillac seville SLS parasitic draw was created by dustin.combs
Hello everyone I've got this cadillac that I'm beating my head against the wall with. Here's the problem battery drains overnight. I can take away power supply to both fuse boxes and the test light i have between the battery and the negative cable stays lit so I'm thinking its something more direct that doesn't run through fuse box any thoughts would help. THANKS

I think Cheryl is on the right track with the alternator since you already bypassed everything by taking the fuse boxes out of the equation.

I've never been able to find a draw with a test light in series, but every one I know does it that way so it must just be me :unsure:
If you strike out with the alternator, I would start from scratch with an amp meter.
