Hey guys, I bought a 2004 Hummer H2 last week and it's having some problems. It'll run for about 5 minutes and the radio goes off, all gauges stop working, battery light comes on, service 4wd and all power goes off inside. Any idea what it could be? I've checked all relays and fuses.
Thanks for any help!

 

Have your battery checked.. A bad battery can make all kinds of weird things happen....

 

Loose battery cables can also do that. Is your running voltage around 14 volts?
