Ok, i hav a 87 gxl and it seems to have a short somewhere. I think the cause of this is a bad ground or a fraid power wire somewhere, but i'm not sure. If the ignition switch, hazard lights, or headlights r turned on the cars body becomes electrically charged, its got power, which is wierd. I can take a power tester to it and it reads that their is a current on the body, the engine, watever. I'm wondering since it seems that only those three items make it do this it can be limited to only a few things. If anyone has any ideas I'd really aprreciate it. thanx
