Power Leak! Battery Discharge!

[YukonJack]

Hi All,

I've tried searching, but to no avail. After two batteries, things aren't going well. I put my multimeter across the terminals and watch the voltage slowly drop. It started at 14.36 and has steadily dropped to 14.17, with the motor running. I have just replaced the alternator, so that shouldn't be it.

A previous owner has wired PIAA lights in, maybe that is causing the problem? Also, my headlights are wired to the battery (they turn on when the van is on and aren't on a relay). Is that it? I'm not strong with the electrical stuff, so please help!!

My bet would be the lights, if you use a multimeter between your battery - and ground then start pulling fuses one at a time you should see where your drain is . I got mine down to .14 amp or miliamp or whatever it is and that was mostly the stereo (memory) and alarm system. Cleaning up the terminals and connectors in the battery bay solved a lot of my power draining issues.
