My fuel gauge stopped working today, and I'm stumped. The gauge is tight again the cluster housing, and has rubber washers so it doesn't ground. The gauge has 12v going to the runtz reducer, which goes to the stud on the gauge. The other stud has the wire going to the sender, which I have unhooked for testing.

There is 12v going to the input of the runtz yet I don't have anything coming out the other side. I had this exact problem with a reducer I was using before, so i thought it had gone bad.

The gauge obviously doesn't even move a little, it is somehow showing no power when there is power before the runtz.

What!?
