\"Jerry Rigged\" it to stop battery drain (any other ideas or help?) Checked each fuze individually, no drain there. Checked the alternator, no drain there, checked everywhere else I could think of.....no drain there. Finally figured out that the drain was coming from that little wire attached to the main positive cable. Disconnect it and the truck won't start. I ended up running a toggle from it into the cab. Now I just have to remember to turn off that toggle every time I get out of the truck. Consequence if I don't......dead battery. But at least I don't have to pop the hood and connect the ground wire to the battery every time I want to drive the truck.
