Ford Repair: ford battery, luck chris, ammeter

Question
I have to unplug my battery every time I get out of the truck because if i leave the battery cable hooked up there is something causing the battery to drain.  every once in awhile the windshield wippers come on even when i dont turn them on.

Answer
hey there, the only way to figure this out, disconnect one of the batter terminals, and use an ammeter in series without the battery connected, and pull out fusees untill you see there is no more current being drawn, that will lead you to the appropriate circuit which is causeing an over night draw,good luck
