Re: Locating a short circuit

I'd have to agree that if you disconnect the ground cable from the battery and if you hook a voltmeter on the battery ground and the ground cable, and you have voltage then you have a short somewhere or what is referred to as a parasitic draw/leak. But the question is where, and how do you isolate it? Most importantly though is heat generation and whether the short could cause a fire.

Ordinarily, if you have a fuse box and turn everything off, you can pull fuses until the voltage goes to zero, then at least you can figure out what circuit is involved. You might not have a fuse box though to work with.

How many volts are present when everything is off?
