1980 Chevrolet C20 Silverado 8 Cyl 5.0L


I have to disconnect battery everynight. Why wont my battery keep charged overnight? PLZ HELP!!!!!!!!!!!!

I have a 1980 Chevrolet Silverado 3/4 ton, I believe its classified as a c20/2500 2wd. I have replaced alternator 3 times and I have a brand new battery. If I don't disconnect the battery at night then it will be dead by morning. I have had mechanic look at it and he's stumped. I keep getting the same answer from everyone which is what I thought in the first place, there must be something that is "always on". I have unplugged interior & exterior cab lights and switches, stereo, installed new battery cables and I'm just stumped. Could somebody please help with this situation? Thanks ~ADAM

Look up parasitic draw and perform the test. Basically you need to hook up an amp meter or test light to your battery cable and turn everything off. You then remove system fuses to pinpoint which system is drawing power when it should not. Then you test the components in that system. On this vehicle I would suspect an aftermarket stereo issue or alternator field circuit. Try disconnecting the alternator at night instead of battery. This electrical system is fairly simple and you should find the problem easily with a parasitic draw test.
