Battery Dying
So, Not too long after I got my H2, I had an aftermarket deck put in. Ever since this, I have had issues with my battery getting drained, and dying. The weird thing, it is happening over night, meaning when I go to unlock it and start it in the morning, it is dead. My other friend did the same thing to his, and has the same problem. Anyone have an idea on a fix? Getting sick of jumpstarting my Hummer, so embarrassing...

Re: Battery Dying
I installed a new deck in mine. If you do not use the specific BOSE/ONSTAR wiring harness it is a night mare!! This might be an issue if it has the wrong wiring harness and its obviously drawing current even when the car is off. If you do have the specific harness ($130) then try checking your wiring again and make sure your not using the direct battery wire for power use the ignition/accesory one its usually yellow instead of red.

Re: Battery Dying
Thanks for the info, I will look into this and see if that might be the problem. The deck that was installed was an Alpine mulitmedia system, and they had to install an aftermarket databus sytem too. Would they still be able to use the Bose harness for that?

Re: Battery Dying
Yes this harness has to be used in order to avoid losing the Chime alarm and allowing the on star system to continue to work. I found my harness on ebay but like I said those little suckers are not cheap. If they didn't use the harness and spliced into factory wiring that spells big doodoo!

this is the one with the premium bose, just look in your glove box for the Y91 sequence in the label and if you see Y91 anywhere you have premium other wise you need this harness.
