Here is my question. Is there a difference between the gauge years. The volt gauge is reading fine, it reads 12 volts easy enough. The TEMP gauge will climb ALMOST to the HOT side and as it idles will drop alittle. I know its not hot because you can feel the engine and the mechanical that was on it didnt read high. I took the gauge out of this 76 tach gauge cluster, would the sender be different between the years. If so I am going to find another gauge, I really dont wanna tear this 76 tach cluster apart.
Also my oil pressure is reading low. Again it didnt on the mechanical gauge and by the way the oil gauge is the electric gauge that was in my cluster. The one in the 76 is mechanical so that would not have worked. Is there a different oil pressure sender I need or could use to get a more accurate reading

>yes!, some use a 3 prong and some use a 2 prong, most 2 prong are ammeters, check with a test light to find what posts are grounds (if any)
>reproduction temp sensors (brass bung) are crap. They dont make them like they used to if u know what I mean. and they will read on a different "spectrum". check needle position on hot idle and take a manual reading, using a gun or good ol thermometer.
Also, temp sensors MUST have an adequate ground for they work using the negative side, in resistance, measured in ohms. Remove, clean all contact areas. Use red hi temp sensor safe goop to seal if it leaks. NOT TEFLON TAPE
>Check all stock lines and connections again.
It sounds to me like the circut board on the back has been damaged. only way to check is to "tear apart the dash" ahah.....
as far as grounds not being adaquite, yea maybe under the hood, in the cab, most likely not. But think oof it this way, if theres one problem, theres bound to be more...
start at the fuse box removing alll fuses and checking for corrosion, and work your way up.
New best friend= a good DIGITAL voltage tester
good luck!
