I have checked and replaced all fuses that I can find and unhooked the auto trunk closer. The battery drains overnight on my 1983 Cadillac Fleetwood. Any ideas?
Alternator. The regular inside the alternator has an open diode. Disconnect the battery overnight and it will start the next morning. The alternator will need to be replaced to fix the problem.
