Hi Jim,
Does the temperature gauge reading ever settle back to a normal reading?
It will be interesting to see what suggestions you get. I fought the same issue and finally replaced the electrical gauge with one of those mechanical dual temperature/oil pressure gauges that other British cars have.  I filled the empty gauge hole with a mechanical oil temperature gauge.
If you are interested I can send you a picture of the center gauges.
Good Luck,
Dave Connitt

 Does the temp gauge go to COLD with the wire disconnected or does it stay =

Jim,

I replaced a nonfunctional temp gauge in my gt6 and the new unit read
extremely high when the engine warmed up. I replaced the sending unit &
voltage stabilizer and it didn=E2=80=99t change anything.

Then I calibrated the gauge -there are 2 adjustment ports covered with
black stoppers on the back. One of them adjusts the needle location. Using
a hand held HF digital sensor I adjust the needle to 185F, measured from
the thermostat housing, to the center mark of the gauge. Seems to work fine
now.

I think it was the adjustment screw on the left side looking at the rear of
the unit. It will look like you can adjust it with screwdriver, but the
metal is fragile. I ground down a hex wrench that fit snug in the opening
with a blade end and it turned easily with no damage.

Pull the wire and gauge goes back down.  Gauge worked prior to resto so will=
 order new sender.  Thanks! Jim
