    I was using brass. Using steel is a good idea.

    Well crap, now I have another reason to pull the dash and replace a couple burned out bulbs!! Is this resister available from a vendor or do I need to find a good used one?

    GAUGE SWAP UPDATE.

    VOLTMETER

    Reads 13v when ignition is on.
    Reads 16v when motor is running.
    Shop voltmeter shows about 13v when motor is running.

    TEMPERATURE GAUGE.

    Need to install correct sending unit.
    Currently reads in OVERHEAT range when car is started.

    OIL PRESSURE GAUGE.

    New oil pressure sending unit for electrical gauge installed.
    Reads 0 PSI at all times.

    FUEL GAUGE

    At first showed correct level and steady but bounced around while driving. Swapped resister thingy from old gauge that worked fine. Reads 0. Swapped in old gauge. Reads 0.

    Working on these for three days now. Getting really frustrated. Really really frustrated.

    Shouldn't the temp gauge show low even if sender is wrong?

    Any help on any of these gauges will be greatly appreciated.

    The only thing I can offer on the fuel gauge is ours had issues with bad contact between the spring clips and the circuit board. I think it was eventually soldered, but by pushing on the dashboard / cluster you could get a reading out of it. Sounds to me like you've got grounding issues or some other contact problem.

    I agree, I think it's a connection problem like dirty spring clips.
