[TR] Thermal Transmitter Temperature Sender help

[DAVID MASSEY]

 Here are some data for the TR8.  This might be close enough for the stag:
Temp C    Temp F    Orig ohms   GTR110 ohms
50        122       332         290
55        131       275         242
60        140       227         197
65        149       193         169
70        158       158         142
75        167       134         120
80        176       114         102
85        185       99          91
90        194       85          77
95        203       74          65
100       212       60          55
105       221       51          48
110       230       44          41
115       239       37          37
120       248       32          31
125       257       28          28
130       266       24          25
135       275       21          22


If you have a source of resistors in this value range you can connect them in lieu of the sensor and check the reading to see if it is close.

I'm going to try and figure out if my Stag is running hot. The gauge always reads high 
I found a note on another forum on how to test the voltage regulator, and another forum how to calibrate the gauge.
I'm trying to figure out how to test the Thermal Transmitter Temperature Sender. Does anyone have any data on how the resistance changes with temperature?
Since most Triumph around the 70's used Smith gauges, I'm assuming the data for the Thermal Transmitter Temperature Sender would be the same.
