[TR] Tr3 temp gage

[dave at ranteer.com]

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?
