I am forwarding this request to the list as a favor. Since the temp guage
on the '3 is non-electric I couldnt answer.
Any suggestions appreciated. Respond to Bill directly at
kearns@hal.fmhi.usf.edu
Thanks.
later...

Subject: TR question
Hi, Carl!
I've been driving the TR lately and have noticed a problem that I need
your advice on. It seems that the temperature gauge on the car never moves
above cold, although the coolant in the radiator is at 77 degrees C.
I have measured the resistance of the sending unit at this temperature and
it reads 7,000 ohms or so. I found that a resistor of 98 ohms was
sufficient to move the gauge off cold to the normal range of temperature.
My question to you is, do you know what the correct resistance should be
for the temperature sending unit when the car is running at normal
temperature? This car has been sitting for so long that I suspect it
could have problems with the voltage regulator. I've ruled this out
since the gas gauge works correctly and it is on the same circuit with
the temperature unit.
Would it be possible for you to check the resistance of the sending
unit (temperature) using a volt ohm meter when you get a chance
and the car is hot? It will, of course, require you to detach the
lead to the gauge in order to get a correct reading.
I would be deeply in your debt, Carl, if you could do this for me.
I have had a few other problems recently with the car, but it is
such a pleasure to drive even when it isn't 100% operational. Makes
me wonder why I stopped driving it, although the weather has been
perfect for it.
Best regards,
Bill
