Fuel Gauge questions

[adam83]

My fuel gauge use to work up until recently. It now reads zero no matter how much gas in in the tank. I disconnected the 2 connectors for the 2 wires going to the sending unit. Then I tested the voltage between the 2 wires on the bike side and got 6.82 volts with the key on. I jumped those same 2 wires and the gauge doesn't respond at all, just stays at E.

Is there another way to test the gauge? If the wiring and connections leading to the gauge turn out to be ok, and the gauge is confirmed to be the culprit, can it be refurbished or rebuilt?

Is the battery fully charged? Harness side should read battery voltage so if its low then charge battery and recheck harness voltage and the jumper wire test.
