Elec. short

Tring to track a intermittend, bad short. Drains batteries within a couple hours. I've pulled all the fuses/relays one at a time and can't find it? Any ideas? Thanks

try disconnecting the alternator.... I've seen several cause a real bad draw like your talking about. When I say disconnect I mean completely remove all wires...

I'll check it out. Do you have to replace or can it be fixed? Still charging. Thanks

they will still charge and work fine, but kill the batts as soon as you shut off the truck.
