Fuel gauge on my D3G (BYR01978) always shows full.
What should the voltage read at the gauge?
Trying to determine if it's the gauge or sending unit.
Is there a way to test either of those?

Turn machine on.
Unplug connector at sending unit.
Note gauge position.
Now, jumper the two terminals on the chassis connector to the fuel sender.
Note gauge position.

If the gauge is good, it will read full one way, and empty the other.
