Hey, I have a 2003 7.3L and I've got a slight problem.. I went to work this morning the truck started up fine, got off and started fine, I decided to go out, truck started just fine. but after a few minutes, the battery light came on, then the ABS light came on... I figured i would let it run for a little while to recharge the batteries, i went to check it, the ABS light and the Battery light went out, but the batteries are dead.. could this be an alternator problem or do i need to buy new batteries?

so i was looking around the forums, and i think it might be the alternator, cause i have noticed my lights dimming and getting brighter every so often. any input?

Also check your connections. Neg battery cables and motor grounds.
