Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Angry charging light came on

hoping someone can help I finally bought my dream truck a 04 H2 have had it less than a week and now the dash went dead and 2km down the road came back on. went out parked it for 20 minutes jump in and now it says bat not charging so limping it home i booted it and the charging system started to charge. Its done this twice now i booted it and bang charging but today the dash is in active and when its running the volts are dropping. I've heard all kinds of stories about this going to check mega fuse but not sure but now its in the driveway sitting i tried to check alternator it read 11.8 and battery was just slowly dropping

thanks for any help

Alternator is dying. Should be putting out over 13V when running.
