Well, I am pretty sure that Triumph temp gauges are not particularly calibrated
to an absolute measure. Instead, you are supposed to know where the needle
rests then the system is "at normal temp". You are also supposed to know
the usual swing you see when running hard under warm conditions. Then if the
needle moves significantly out of that range, then it is "bad". I too wish that
there was some way of knowing exactly what the temp is, and whether that is
"bad".
I suppose it is possible to calibrate your gauge by removing the sensor from the
engine and placing it in hot water after grounding it to the engine. Then turn
on the ignition and watch the needle. Compare that to the temp you read on a
thermometer. Heat the water up to boiling and watch what the needle reads.
Now you have calibrated your temp gauge. I do not know if there is a way
to "zero" the gauge so 185 F (or whatever)is centered. I wish there were as
mine reads 5/8 to 3/4 of the full scale at "normal" temps (185 thermostat and
winter temps outside).

Subject: TR6 Temp Guage
To the list:
Is there a reference available that tells what the temp guage readings for
a 76 TR5 would be in degrees? Since the gauge is marked as C - 1/4 - 1/2 -
3/4 - H, it is hard to tell what the temperature really is. TIA
