I did a few tests this weekend...

do you have access to some resistors and perform a test of the gauge's calibration like BRYSKE (Chris) performed.

measuring the resistance of your installed sender would be a start. If it's value is in the COLD region, that alone would indicate a bad gauge

added...

Measure the resistance of the wire to the the gauge with switch off and the voltage of the wire unplugged from sensor with switch on. this will let you know if the gauge is grounded at the dash. the gauge as a "voltage divider" should have about 0.45 X battery voltage at the unplugged sensor.
