To be honest Liz unless the guages are really doing strange things I wouldnt be too worried about calibrating them.
They werent the finest bits of measuring equipment when they were new.
Your fuel guage is okay if it moves the right way. If it says full or pretty close when you fill the car up that was about what they did when new.
Your oil guage should read a bit above the bottom when you start it up and idle. Once its warm at idle it wont show a huge deflection anyway. It will come up at revs not too far above idle and will sit fairly well in a bout the same spot.
Work out where its roughly normal spot is and remember it. Sometimes when warm and at idle it can read close to zero. Did that from new anyway.
Temp guage will come up and sit again around the same spot. Again find out where normal range is. The biggest problem you face with a temp guage isnt it going up. Its when it goes down you hit the panic button. Usually means youve lost your coolant. If it does this then goes back up it starts getting expensive quickly.
Again with the volts it should sit in a normal type spot. It will probably flicker with things such as the blinker. Nothing to worry about.
The oil water andvolts guages are roughly set so that they sit at or around half deflection when things are normal.
If they are around this position I wouldnt worry too much about the expense of calibration.
The tacho is generally pretty good with its readings but a hundred or so out again is nothing really to worry about.
If the guages were high quality stuff from the factory none of the race teams would have bothered putting aftermarket stuff in.
The race teams also used to run guages and lights, well one light.
They added guages but kept the switches for indicator lights as well.
They put the output of the switches to a big light you will see on most of the cars of the era.
If the light went on it meant you had a drama and you needed to pay attention to the guages to find out what it was.
Thanks for that, Rob. I'm sure you are right in what you say.
Yes, the water temp and volts seem okay to me. Fuel is a bit out I think because it only reads a max 3/4 when I fill the tank and I tend to refill when it reads 1/4 because I don't trust it...or myself seeing as I've become accustomed to having an idiot light for fuel in the daily
I've been quite slack with my other Torana, which has never had a working fuel gauge, odometer or speedo so I was trying to get in early and have this car all sorted out at the beginning of my ownership.
Cheers,
Liz
