harlequin Posted November 27, 2024 Report Share Posted November 27, 2024 (edited) I'm looking for a Tr4 electrical water temperature guage. It's the type with the needle pointing down I don't mind if it's flat or domed glass or even no glass Please send a PM if you have one going spare George Edited December 5, 2024 by harlequin Resolved Link to post Share on other sites
Lebro Posted November 27, 2024 Report Share Posted November 27, 2024 (edited) I believe the needle points down on all the TR2-4 variants. The electrical ones all work the same, the later ones with the top of the needle shielded are actualy the same inside as the early ones. you can also fit the dail from a capillery type (TR2-3B) to any of the electrical ones (which is what I have done). The tricky bit is calibrating the gauge to match the sender. Electrical gauge with capillery dial Bob Edited November 27, 2024 by Lebro Link to post Share on other sites
harlequin Posted November 27, 2024 Author Report Share Posted November 27, 2024 Hi Bob It's actually for my TR3 which has a TR6 guage with the shield removed but it looks a bit odd because the needle points up. I thought electric as opposed to capillary because the car is setup that way already. It's all part of crossing off of the long list of niggling little faults with the car George Link to post Share on other sites
Lebro Posted November 27, 2024 Report Share Posted November 27, 2024 I changed my '3 to electric because with the capillery setup it was impossible to get properly behind the center dash to do any work because the capillery pipe could not be disconnected. I did however wish that the change was not detectable, so did the dial swap. Bob Link to post Share on other sites

I did briefly consider fitting the inards of my TR6 guage upside down into a non working capillary guage that I have, but realised it would be working backwards. The other downside of the capillary type is the bulb quickly becomes stuck in the cylinder head, so any head or dashboard work then has a potential extra complication George Link to post Share on other sites

George No to conversion - not really feasable. I ended up buying several electric gauges from various places, & actualy ended up using a TR4 fuel gauge innards with the TR3 Temperature dial. They are all the same inside ! The fuel one was less troublesom to calibrate accurately. it is a very fiddly operation ! Bob Link to post Share on other sites

Bob I make a point of avoiding anything that involves removing the centre dash panel because it was so much hassle to fit it in the first place I don’t want to go back there. Rgds Ian PS I did manage to replace my failed temperature gauge earlier this year without removing the panel. Link to post Share on other sites

George Yes I know they all seem to be going for that as a flat rate, postage is dear now anyway and also the insurance on stuff if its worth good money has jumped as well. Stuart.
