(1)pull the wire off the sender unit and earth it out on the body with the ignition switched on,watch the gauge if it rises yo full your gauge and wiring is ok and the sender is at fault.
(2) if the gauge does not move and your earth is good check that continuity exist in the wire from sender to gauge if you don't have access to a multi-meter visually inspect wire from start to finish.if its ok check there is power at gauge if there is good chance its your gauge

Re: XC fuel gauge

The resistance at the sender should be 73 Ohms when empty and 10 Ohms when full.

Re: XC fuel gauge
