I have a 2000 Ford Excursion 7.3L and have been having electrical problems. My batteries consistently die and I have had several mechanics look at it. I have replaced the batteries several times over the last couple of years because they are always dying on me. The truck was not driven every day, so the only thing we knew is that there was something drawing from the batteries. We could never find the problem. After sitting for 2 or 3 days, I would go out to start it and it was dead. Now, my mechanic has had it in the shop and we have narrowed it down to a specific problem. When the key is OUT, the driver's side door dings when opened. That is only supposed to happen if the lights are left on. The windows roll up and down as well. All of the accessories stay on. Even the radio.

The mechanic removed the Body Control Module and took the fuse out of it. The fuse was not damaged. He put the fuse back in, and it seemed to re-set everything and fixed the issues. We let it sit for 2 days in the shop, and now it is dead again. HELP!!!!!
