Is there any information or a chart that shows the resistor values for the different gauges and years they belong to?
The two that I have checked for the Y88 is:
Fuel gauge resistor has a ohm reading of 88....Blue
Volts gauge has a resistor ohm reading of 126.....Orange
I also have some gauges from a 1975 Trans Am that have an ohm reading of 86 and 88 for both volts and fuel.
