Can anyone give me advise on how to test my fuel gauge/sender unit
in an xc falcon. I bought the car with it not connected, and cant seem to
get it to work!

(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

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

Hi I have a problem with my gauge also. It seems to work alright then when Im driving around it drops out and shows empty (even though I know its full). It either stays that way or sometimes comes back.....help. Is it an eath problem and if so how do I fix it
