I have a 1995 F150, 5.0L, 5speed standard, with about 155,000 miles on it. it recently started having an electrical problem. When it sits for a couple of days something starts to drain on the battery. At first it was about 10 days while i was on vacation, and i returned to a dead battery. No lights, radio, etc... were left on. The second time was about 10 days also, with the same results. Now it has only been a couple of days, and the battery is dead. Any help or suggestions would be greatly appreciated.

 

check the batt for a dead cell.

 

It's a reported fact that even the dome light, if left on, will drain your battery. So, maybe you have some small electrical item that is draining the battery. Does your truck have an under hood light? if so, maybe it's on when the hood is down. Check that cigarette lighter too for a defective / jammed connection. Don't forget any aftermarket items you may have added.
