Question about 2004 Chevrolet Avalanche
I used my truck to jump a friend's vehicle which had a dead battery. A week later, my wife called me at work to explain that our truck would not start and that none of the lights on the dash would light up. She figured that I left the door open and the dome light ran the battery down, but I explained that was impossible, since the computer automatically turns off the dome light even when the door is open for a period of time. I have done nothing to it as far as adding anything electronic. I cahrged the battery using a wall charger, and started the truck and drove for about 45 minutes. brought it home, and made sure the doors were compoletely shut and turned off the radio. 5 days later, dead battery again. (we only drive it about once a week.)
I ran to the nearest automotive store, and bought a new battery, figuring I had ruined the factory battery somehow. I turned off everyting I could, including the radio, and dome light... A week later, the same thing happend to this one. Any possible solutions? I've read that updating the firmware fixes this due to a computer malfunction. Couldn't I just unplug the computer for a lenght of time allowing it to re-set, or re-boot?
I had the exact same problem! On the third battery and the third time in our local Chevrolet Garage...they told me they couldn’t find any problems. My response was, “this vehicle isn’t dependable and it’s staying here until you fix it.” Well what do you know about a week later and a $100 deductable on my GMPP warranty they found the problem. It was an accumulation of three issues but mainly one.
1. The LoJack system that a different Chevrolet Dealership installed was drawing a constant 20mA when the vehicle was off. Within LoJack specs. Normal.
2. The Prodigy trailer brake controller was drawing 15mA. Within specs. Normal.
3. And the MAIN CAUSE of the whole problem was the HVAC controller never turned off. It was continually drawing 35mA until they pulled the fuse. They had to order another HVAC controller which would have cost $287 and a weeks’ worth of shop hours to investigate the problem. Thank GOD they only charged me the deductible on my warranty.

I think I'd take a good look at all the fuses under the hood especially one marked "alt" or "charge" . If nothing else, if you have access to a multimeter/voltmeter, check and see what voltage is at battery before and after starting. I'm thinking a fuse blew in charging/alternator circuit when you boosted other vehicle, and all your running off is your battery, with no charging going back in to it when engine running.

You may have ruined your alternator when you jump started the other car. If the alternator has a shorted diode it will drain your battery. Try disconnecting the battery wire from the alternator and see if the battery goes dead then.
