2003 Silverado Electrical Problem
The battery in my Silverado was dead Wednesday morning. Jumped it and took it to Wal-mart to get it checked out. The put a new battery in it and checked the alternator. Everything checked out OK. Got in it this morning and it was DEAD again! Any ideas what could be draining this? I don't see any lights, etc. on. I'm stumped....

check for corrosion on the battery cables, constant draining usually indicates an electrical short somewhere, I still say start with the cables and look around them. good luck

If your battery is going dead overnight, you have a componant that is powered up that is causing a draw on the system. A parasitic load test on the electrical system will have to be performed to determine what is causing the draw. Quote:

notice the keywork "USUALLY" I work with electricity everyday, Im an electrician on some very expensive military aircraft, ive also been doing it for many years. It doesnt matter how old it is parts can still internally short causing a drain, all i was doing was giving a starting point, most common battery drains come from a faulty component, ie.. battery cables, alternator, starter solenoid etc etc..... the point im getting at sometimes you dont need to look that deep into things to find a simple problem. start small and inexpensive.
