Bob, I've checked that circuitry out, and there is little or nothing else
that can go wrong. If theres a problem in the voltage stabilyzer (power
supply for the guage), it will show up with crazed indications all over yer
instrument cluster.

You can pull it and heat it suspended in a pan of hot water and take readings...

Look under your upper radiator hose where it goes into the engine. It will
have a large rubber boot on it with 4 (mol) wires coming out. Don't feel bad
- one of my latest ones have started acting up. Luckily I have a spare. If
you want, I'll ship you my old one. It is intermittent, but you can use it
to see if thats it. 
Takes less than 5 minutes to replace, loss of 1/2 pint of coolant if yer
quick and the engines cold. If its hot, coolant loss depends on how long you
do the OMIGOD dance clutching yer fingers and writhing in pain. I'm changing
out mine this morning (cold)...
