You bring up a good point Pepi.

There should be some lesser voltage, because the resistor in the gauge should allow some flow thru the two coils left in the circuit while the sender is disconnected. I would have to go out and disconnect to see how low it might go. I've done that reading before but cannot remember what is read exactly, I was just looking for an open circuit voltage presence at that point back at the sender.
I'd go do it now, but I just don't have the time today.

Adam, the grounding test at the ribbon connector under the carpet would still be a good test for proving or disproving the gauge and dash wiring to be good.
