I have an electrical problem with my H-1. My lights are flashing with the switch turned off. I've checked all the relays and pulled all the fuses one of the time. And I don't have an alarm system or remote start. So my question is this.
Where are the main groundstraps for the Hummer H-1. I need your general location in relationship to the vehicle.
So I can check their continuity.
But I have no idea where to look for them.
Can anybody out there help me.

Thanks in advance
