Asked by Nov 04, 2015 at 12:11 AM about the 2003 Chevrolet Suburban 1500

Question type: General

Hi I have a 2003 Chevy suburban.
And lately I would have to jump start
it everytime. I mean it would be
literally dead. I've had my battery
tested my alternator tested and so as
my starter. I don't know what else
could it be? Please help me find out
what I need to do.

Ok, so the battery is good, & the alternator is good. There must be a draw on the battery. You can check by disconnecting the neg. ground cable, and put a volt meter between neg. post & neg. cable. Really should not be drawing more than 1 volt. To help in finding out where it is coming from, you start pulling fuses until the voltage drops on the meter. Once this happens then you will have a clue of what circuit is drawing from the battery and then look for a fix.
