Just to be clear, I've got a two wire "harness" type plug at the back of the fuel gauge. I measured both wires. One is clearly the B+ in showing switched power of 11.8 VDC, the other goes to the sending unit, which I got 2.8VDC. I got about the same reading at the junction behind the seat on that wire.

What's troubling is the .8VDC at the gas tank. I examined the wire from the junction to the tank and it looks fine. I was tired and it was late, so I stopped short of putting a jumper wire at that section.

But I feel that I'm not getting accurate readings with my cheap Sperry Multimeter. So I'll buy a better meter and start again.

But, why the heck is my gauge not going to E when I ground the sending unit wire right at the gauge or when I grounded it at the junction behind the seat? Regardless of my readings, why won't it ground to "Empty"?

I'm not totally clear on this:

Are you sure you are getting a good ground for your meter back at the tank? Maybe try to run a wire all the way to the battery neg for your meter so you know you have a good ground, or the same place you are using when you check the junction behind the seat.
