Need some help on this one, my truck was dead the other morning tried charging the battery it never took a charge. I bought a new one put it in my truck and within 3 hours the battery was dead. I charged it put it back in tested the volts everything read fine. I checked the volts about 40 min later and i was down from 12.52v to 12.16v , I disconnected the alternator and checked again 30 min later and i was down to 11.69 volts. What could be drawing off the battery to kill it so fast? and yes everything is off i.e lights and radio....

 

I did a search on YouTube for "parasitic drain."

This one was on a Chevrolet truck.


Even if that one isn't the one you need, I am sure some of the others will help.

 

Without watching the vidio, what I do is hook voltmeter to battery, and individually pull fuse's till the drain stops. That will pinpoint your issue. In your case, you may have more thatn one issue, but that procedure should help you locate the problem.
