Wire shorted or damaged in engine bay? Connects to sensor on cylinder head at front near thermostat.

Are the rest of the gauges working properly? If not I might suspect a bad voltage stabilizer...

Sounds like a bad sender, then. Not the first time I've seen one of these go bad. SImple fix.

What makes you so sure the engine is not overheated?
If you take the wire off the sender unit does the temp gauge drop back down to cold and back to overheat when you short the wire to the engine?
Check the earth continuity between your engine and the bulkhead instrument panel.
A bad earth can give you all sorts of spurious readings.

Hi maxcomx,
The engine is running sweet as a nut. Cleaned all the wiring and the gauge worked well for an hour or so. I have a new sender as the old one will move from cold to normal to hot and then to cold again and never sit in the same position for long enough.

Ran into a similar problem with the sender in my 110. Check the seating of the tab on the crimp on top of the sender - if it is loose the resistances can be all over the patch. That had to be the only electrical problem i ever fixed on a landy with a mallet and a pin punch.
