When Ron wired the instruments for my GT40 he used the "authentic" Smiths gauges that I had bought several years ago. This included an oil pressure gauge, a fuel gauge, and I think a water temp gauge which are all supplied with (I guess) a modulated 12 volts from the Smiths voltage stabilizer. We have just started to get everything working, and it seems to be evident that the three gauges that are wired to the voltage stabilizer don't work as they ought to.
Does anyone have any particular knowledge of these items and what they do, and is the voltage stabilizer necessary? I will call Nisonger Instruments on Monday, but I thought I might get some information from those more informed than I (which is just about everyone, on this particular topic) We followed the wiring diagram provided by Smiths exactly. I have no idea whether the thing itself is working as it ought to be. Also, does anyone know whether the case of the voltage stabilizer needs to be grounded? (I don't have the wiring diagram handy as all the cars' paperwork is with the car, not here)
