fuel gauge stopped working

Checked grounds, unplugged wire to sender unit and the wire is getting very dim power to the sending unit. The funny thing is that the fuel gauge is reading max over fuel it is all teh way to the right screw in the gauge. I wonder if the actual gauge is bad. I have a spare 92xj cluster, but i wanted to ask for ur guys help before i swap out the fuel gauge. Any one have an idea on my next move?

89xj

anyone?

Dim voltage?

My 93 FSM gives the following for the sensor. If it's pegged full, then the wire is most likely shorted to ground or the gauage is bad. It should read empty with the sensor unplugged and full with the sensor shorted.

FUEL GAUGE RESISTANCE TABLE
Empty ................................................ 105 ohms
1/2 Full .............................................. 33 ohms
Full ................................................... 5 ohms

so my gauge is bad. can i swapp the gas gauge out of a 92 board into my board.

so my gauge is bad. Can i swap the fuel gauge in teh 92xj cluster and put it in mine?
