[TR] Tr3 temp gage

[William Brewer]

Hi Dave,
     I just went through this myself. I was getting ready to send my
temp gauge in to West Valley Instruments. It was $150 to rebuild the gauge or
$200 if it needed a complete new bordon tube. I have already had the gauge
rebuilt twice before during the last 15 years. I found that the early TR4
gauge looked identical to the TR3 gauge, but used an electric gauge so I
bought one of them for $150 and spent about another $30 on parts to install
it. It was a risk buying a used gauge, but it all worked out. With no bordon
tube it should last much longer, hopefully several more decades.
     Wayne
Bier at Triumphs Only (I know, I know - lots of bad reviews from the list)
charges something like $150 for the used/no guarantee early TR4 gauge + your
TR3 gauge in exchange. No exchange gauge? Then no deal. He will also sell you
a rebuilt gauge for something like $250 + your old gauge in exchange.
     The
TR4 gauge requires a voltage stabilizer and sending unit. Moss has both. TR4
wiring diagrams are on the web.
     I kept my old TR3 gauge as a spare.
   
 There is also a guy selling "clone" TR3 temp gauges on Ebay for like $75.
They look almost identical except where it is supposed to say "Jaeger" it say
"British Made". These look okay to me as well.
     I like my TR4 route.

Late tr3. 
Have not had the car long.  Finally running and driving today.
Looks like all
the gages except tach and temp are finally working.  Tach
screams; its
probably bad.  Temp gage is lifeless.  Other than confirming its
lack of
response by puting the sensor in hot water, is there anything else I
can do? 
I guess I have to send the gage and tube out?  Any other options?
