    Anyone know what the wire wound resistor values should be on the guage for Generator, parking indicator, Fuel, oil, and temperature?
    I have three of them.
    I know they are for the meter movement.
    Two of them measure ~ 38 Ohms, and the other for the Hot Cold meter is 144 Ohms.
    I suspect 144 ohms is for the gas, or maybe not the right value?
    What should they really be?
    Are these the correct values?
    Can I replace them with precision resistors?
    Thanks in advance as I don't have a schematic.

    :TU: The resistance should be ~ 42 Ohms on all three current limiting resistors for your meter movements.

    This will cause your meter movements to be bad on the stock guages if not.

    I replaced the bad one. It literally was burnt to the trace.
    I'll see if I can get a picture.
    I'm sure you all have these in your car.


    Thanks
