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.

Default Parasitic drain non fuse any thoughts?

Just checked all the fuses. The multimeter stayed at .15 ma. Didn't move. Does anyone think it could be the air bag module under the skid plate? Open to all ideas. Thx everyone.

There has been several threads on this before but one important aspect is that (according to GM service) at least one module takes up to an hour and a half to fully go to sleep. I forget which though... Do some searched on here and you should find plenty of more info.

A milliAmp (mA) is one thousandth of an Ampere.

Isn’t a few mA draw normal, to keep clock, memory, etc going?

Don’t know what normal is for the H2’ but it is more than zero.

More importantly, how are you driving around with the air ride unplugged? Did you convert to springs? Who left 2 connectors dangling? Those do not unplug themselves. Sloppy! If there is mud in your engine bay (there it is in the photos) then those connectors are full of mud by now.

I could be reading it wrong and draw is fine, do have a fluke meter coming in a few days. Im pretty sure it should say .05 or around that. Its been that way for who knows how many miles 50,000 maybe more. The rear wiper blade button was upside down when i got it. The cord was unplugged. Crazy…
