mackev Posted February 18, 2020 Report Share Posted February 18, 2020 I had a problem with the electrics on my TR4, the overdrive was not working. A local man came at the weekend and managed to fix it, the problem being a wiring fault, yes it's all working now, he is very helpful. However, when repairing the overdrive wiring he managed to put a charge/spark through the dash with a live wire, and now the temperature gauge and the fuel gauge do not work. I had a problem with the Amp meter once before and I bought a new one. But it sticks out like a sore thumb, it is too nice and bright and shinny. Instead of buying new gauges, is there a company you could recommend that can repair the old ones. I would be very grateful for any help here. My Dad used to say 'do a job and make a job' when he worked on his car. How right he was. Quote Link to post Share on other sites
signalredshaker Posted February 18, 2020 Report Share Posted February 18, 2020 (edited) I have had a few of mine refurbished by this company- not inexpensive, but one has to pay for a quality job I think. They also were able to supply new chrome bezels of the correct profile for those I have yet to get sorted. Best time to send them is October of course, when their turn around is a bit shorter. My fuel, temperature (send them the sender bulb with your instrument and it will come back calibrated properly) all around £60-70 pounds. My oil temperature instrument was a little dearer but they did replace the whole of the sender "wire"- it came back looking new- and it now works. All those prices were a couple of years ago so may have changed a little. www.speedograph-richfield.com Edited February 18, 2020 by signalredshaker Quote Link to post Share on other sites
MikeF Posted February 18, 2020 Report Share Posted February 18, 2020 The temp and fuel gauges work off a common supply which is from the voltage limiter in the top right of drivers footwell. Behind carpet So before changing gauges you should check the supply from that isnot displaced and that there are volts coming out of the unit.. Mike Quote Link to post Share on other sites
RobH Posted February 18, 2020 Report Share Posted February 18, 2020 +1 If both gauges have stopped working it must be something common to both and the voltage stabiliser is the most likely. The spark could be a red herring too - he may just have disturbed a connection. Quote Link to post Share on other sites
trchris Posted February 18, 2020 Report Share Posted February 18, 2020 +2 Agree voltage stabiliser has probable been spiked buy the new type that are available they give a more stable voltage output . You may even find the gauges become a little more accurate as well. Chris Quote Link to post Share on other sites
peejay4A Posted February 18, 2020 Report Share Posted February 18, 2020 (edited) There’s a fuse in the supply to the instrument voltage regulator. If your brake lights don’t work (same circuit) then check the fuse box. Edited February 18, 2020 by peejay4A Quote Link to post Share on other sites
mackev Posted February 19, 2020 Author Report Share Posted February 19, 2020 Thanks everyone, I will not be gardening tomorrow as planned, my head will be down in the footwell or ordering the voltage stabiliser, Cheers Quote Link to post Share on other sites

Mike On a LHD car is it in the top left of the driver's footwell? Pete Quote Link to post Share on other sites
