I was checking to see which pin has power on the connector that comes to my radio in my H3 Hummer (2007). I found the power in the orange wire in the upper right pin, but unfortunately the wire i was using touched ground and sparked a little. Since then there is no longer any power on that pin. I thought that I just blew the fuse. However, I have checked fuse #13 and it is fine. Is there another fuse somewhere that could have blown? Do you have any other ideas of what the problem is?

 

Well, I figured it out and am a bit embarrassed. However, I thought I would share the solution in case someone else makes the same mistake. When I was looking at the fusebox, I didn't realize that the "bottom" of the box was toward the cab of the vehicle when looking at the fuse diagram. So, I was testing Fuse #48 (which I thought was Fuse #13)! So, when I realized that I was looking at the world upside down, I found Fuse 13 and it was blown. Simply replaced the fuse and all is well!
