Ernest Posted December 13, 2021 Report Share Posted December 13, 2021 Well I am still trying to sort out the temp gauge going immediately to hot, when the engine is cold, issue. The car is booked into Rees Bros to sort our the timing chain cover oil leak and renew thrust washer and I asked Andy to renew the temp gauge (I have replaced the sender). Andy says (and Rimmers confirm) that you can obtain a replacement gauge. So, my question is: does anyone know where I might obtain a temp gauge for a 1972 CP (do black rim). Andy say that they will be able to strip the current one down to see if it can be fixed, but I would prefer new one (the old one is quite 'knocked about'). As usual, any advice would be much appreciated. Best Wishes Ernest Quote Link to post Share on other sites
Waldi Posted December 13, 2021 Report Share Posted December 13, 2021 Hi Ernest, New (repro?) Smith instruments are still made. https://www.caigauge.com/ This company has been recommended by others on this forum (I have no experience with them). I would also order a sensor from them, so both will match (there are different sensors on the market. Waldi Quote Link to post Share on other sites

trchris Posted December 13, 2021 Report Share Posted December 13, 2021 Hi Ernest Have you tried TRGB? Chris Quote Link to post Share on other sites
Crawfie Posted December 13, 2021 Report Share Posted December 13, 2021 I exchanged my gauges with the TR Shop . Nice !! Quote Link to post Share on other sites
Z320 Posted December 13, 2021 Report Share Posted December 13, 2021 (edited) I had "the same" issue - but always ice cold, this happened after I had the dashboard with all instruments out some years ago. The thing is, I should have the older generation of gauges in my TR4A - which are simple but voltage sensible. Rob and Peter told me the one I have in my 4A is one of the new generation with a plus and a negativ coil - making it not voltage sensitiv. They helped me to find out how the cables have to be connected correctly - and since that it works lovely again. Sadly this forum is a big heap and I cannot find the thread again.

Waldi These are not repro Smiths Instruments but made off the original tooling or new tooling that has worn out but some of their products have been modernized to digital. They also make aircraft instruments and are CAA approved!!!! Bruce. Quote Link to post Share on other sites
YankeeTR5 Posted December 14, 2021 Report Share Posted December 14, 2021 As per Crawfie, TR Shop has a wide assortment of used/refurbished guages. Used them for some TR3 stuff I needed a few years ago and was happy with what they provided and the cost they charged. Quote Link to post Share on other sites

Cheers, Robert I recommend to make a short test with the cable to the sensor: what does the gauge indicates with the cable plugged to the sensor, and what does it indicates when you ground this cable on the thermostat housing?

Ernest Posted December 14, 2021 Author Report Share Posted December 14, 2021 Thanks all for the range of helpful advice - I am trying to work though suggestions. The TR Shop do have replacement gauges - on an exchange basis. And they seem to be nice people to deal with. Thanks for the head-up on this Crawfie Best Wishes Ernest Quote Link to post Share on other sites
Richard Pope Posted December 14, 2021 Report Share Posted December 14, 2021 I have delt with both CAI and Speedy Cables (who are next door) several times. Why not send the gauge to CAI and get them to check and repair and match to a correct sender. I did this and now have a 100% accurate gauge. (Temp senders and gauges are usually not very accurate) I would tend to use CAI for this task. Tip? Neither company really reply to e-mails so phone first and sort it ot the old fashoned way. They are very helpful. Quote Link to post Share on other sites
Ernest Posted December 14, 2021 Author Report Share Posted December 14, 2021 Thanks for the tip re. sender/gauge matching Richard and the recommendation for CAI. Best Wishes Ernest Quote Link to post Share on other sites
