A lot of things can be the problem. It could be the battery, a pinched/shorted wire, bad ground, something is staying on like a glove box, trunk, map or vanity mirror light. If you have any aftermarket electronics like radio, alarm or remote start, they could be wired incorrectly.

You may have a big time short. To prove this, disconnect the battery and with all the power accessories off. Now touch the battery cable to the battery. The bigger the spark the bigger the short.


Ditto to what Mark said. Double check the wires you unhooked and reattached. For a charged battery to go dead that quickly it should be something obvious.


it wouldn't hurt to have the battery load tested.
