My car is a 1964 series IV, if you find one that would be great. I have fixed the temp gauge now but it would be useful to have. Turns out the new sensor was no good so I re fitted an old one and it worked straight away!
Hi, have all the diagrams, just need the year of the car. Two slightly different circuits. Have you tried your fuse box? Sometimes fuse holders get corroded a bit and stop making contact. Let me know if you want any of the diagrams. Cheers.
