Got a 1997 F150 4.6 4x4. the electrical system has gone completely crazy. alt. is charging the battery, it'll hold a charge for about a week an a half. then one time starts up fine, and i'll shut it off go to turn it back, and not even have interior lights. let it sit for an hr. and it starts fine. checked every fuse, every relay, un hooked all extra lights and accesories. this is like, the 5th battery i've had since getting the truck. about 2 an a half years old.

thought it could be a bad batterym but the odds of hacing 4 "bad" batteries doesn't seem right to me. just seeing if anyone else had gone through anything like it. cause this whole work for 2 weeks, then one day just stop. its not working for me. any help would be greatly appreciated.
