Electrical problem
2004 Chevy Silverado 6 cyl Two Wheel Drive Automatic 16700 miles

My truck drains its battery faster than I think it should. I don't drive it daily, and if you let it sit more than about 2 days, there won't be enough voltage in the battery for the truck to start. (Especially in cold weather) The battery was new 4 months ago. I got a load tester and the battery tested fine, I also had the alternator bench tested and it put out 14.5-14.8 volts and the diodes were okay.

Today I pulled fuses with the ignition switch off to see if any of them drew amps and found four fuses that did:

Radio- 0.63amps
IPC/DIC- 0.4
TBC BATT- 0.06
HVAC/ECAS- 0.02

Is there any reason that the radio is drawing 0.63 amps? There is some kind of security feature on it, and a red light that blinks all the time, might that be the problem and is there anyway to turn that off?

I'm not sure if this will help or not, but I have seen similiar chevys that will not let the bcm go into sleep mode if there is a dvd in the player.
