electric temp guage with no V regulator
Posted: Fri Feb 22, 2019 5:50 pm
Hi all,
I have had a good old search of the electrical forum, but cannot quite find the info that I need.
Mine is a 1959 Minor still with original, gold-faced speedo, which I believe means that there is no voltage regulator.
My mechanic (did his apprenticeship on Minors so unlikely to be a duffer) has fitted a new electrical water temperature gauge for me, as the Smiths gauge previously fitted was hugely under-reading. I fear that some of the ether may have escaped when it was removed during the engine rebuild. He has taken the feed off of the fuel gauge, however it seems that the temperature gauge is over-reading, it is idling around 120 degrees. I am sure he has tested the actual temp, but I will do so with a kitchen thermometer on Monday when I collect the car!
He has suggested that this over-read is due to a lack of voltage regulator. What is the usual course of action for this problem, assuming that others have encountered it before? I have only basic electrical knowledge, so any baby-step info would be much appreciated!
Many thanks,
Edd
EDIT#
Having changed my search to voltage stabiliser, I have found this:

If I fit this between the feed from the fuel gauge and the temp gauge, will that work? I think I could just about manage a couple of spade connectors!
