THAT WAS IT!  I went out to refill the gas tank, and afterward the fuel
gauge was pegged almost out of sight to the right.  Never saw that before,
so I finally accepted the likelihood of a voltage stabilizer problem.  After
reading Jonmac's post, I first looked for a loose ground at the stabilizer,
and that is exactly what I found.  After tightening, the fuel gauge read
full but not beyond, and the temp gauge stayed at its old spot, just below
1/2.  Finally, peace of mind!

Thank you all so much for your good advice and especially to Jonmac.  What a
list!

While the Triumph I'm talking about wasn't a TR6, I had a similar problem
with the combi instrument on a '73 2000 saloon. The engine temp and fuel
gauges on the combi clock both gave higher engine temp and lower tank
content readings. Wasn't anything I could find that was amiss on info going
into the instruments but I eventually traced it to a bad earth (ground) on
the instrument stabiliser. Fitted a new one and still the same result. In
the end and more out of desperation than anything else, I fitted a separate
wire from stabiliser to a good earth on the car body. Problem fixed! Gauges
worked fine after that and no more trouble. Might be just that simple?
