Kudos to Dan Masters and George Richardson for their advice on correcting my
over-zealous temp gauge.
History - on TR3 driver I have messed up two original type rebuilt temp
gauges by breaking the capilary tube ($250 down the tube - literally).
Since this car will never be concours, I decided to install a new TR4
electric gauge I found in my parts pile. Bought a sending unit at local
Moss distributor. Problem was it was reading 240+ at the gauge but only
190 at the sender.
Ended up I have a mismatched sender & gauge. I installed a 3 watt 25 ohm
reostat from RadShack in line between hot feed and gauge. Tweaked it until
the two read the same. Have tested it at a variety of temps since then 165
- 210 and the gauge is right on the money now. 185 is 185. High and low
ends are off by 2 degrees to the outside.
Sure is nice to know that the car isn't overheating.
