either cahrging system issues or a constant voltage draw. have they ck'd both?

Supposedly everything has been checked and nothing found. I lean toward the constant voltage draw, but don't know what could be draining the voltage.

could be anything from dome light socket to wiring. is it still under warranty?

Define SEVERAL days! 10-20 or more? Any add on equipment? Original AC Delco battery?
Replyloyal gmc owner, February 25, 2013, 14:39Rookie
7 to 10 days; add on equipment - ham radio and emergency lights - Original AC Delco battery. We have asked the dealer's shop to check wiring on ham radio and emergency lights - supposedly no problem.

Once a Delco battery goes 'dead' it is pretty much shot!! Different electrolyte. This i know. Try an Interstate Megatron and fix this problem!
Nothing at all wrong with an AC battery, good stuff, but once they are drained completely, not many recover!
It is close to 4 years old by now, depending on battery production date!

I'm sure you won't like this , but in order to absolutely rule out the acc. lights and ham radio as current draw , maybe disconnect them for a couple of weeks. BUT .... maybe BEFORE that get a new battery, Agree with wetry on that.

Wetry and Ziptie, thank you for your words of wisdom. We will replace the battery and follow up with results!
