Electrical drain - c4 corvette

[zr1crzy]

Does anybody have any knowlege or experience in finding an electrical drain in an 84 Corvette? I have had it in for service more times than I can count and all they do is replace the battery and/ or alternator.

I'd try pulling fuses for the accessories until you find which fuse when pulled no longer kills the batt. Then at least you narrow it down to the accessories on that circuit...

Hook up a test light on the negative side of the batt between the cable and the batt , pull on fuse at a time , when the light goes out you will be able to tell what circuit has the draw, that will narrow it down! Ron

Thanks. I'll try that. So I put the tester between the negative cable and the negative post of the battery? Probably a dumb question but why does pulling the fuse in the circuit with the draw make the light go out and not when there is no draw.
