    1963 Fuel Gauge Calibration

    Guys,

    Can anyone give me an idea as to how to calibrate a fuel gauge?? Here's the problem. I needed to pull the dash today on my 1963 in order to replace the ammeter which was defective. As I was removing the two gauge mini-cluster (with the fuel gauge) the needle pointer fell off the fuel gauge. I can put the whole thing back together but before I do, I need to get that fuel gauge needle properly aligned. By applying a small voltage (like 9V) I can get the needle to deflect stop to stop so the mechanism is working.

    Question, is there a particular voltage which will make it read say full???

    Thanks, Joel

    Joel -

    Remove the brown gauge wire from the "S" terminal on the sending unit and use a jumper wire to ground the connector, and the gauge should read "full" with the key on. Then disconnect the green power wire from the "I" terminal on the sending unit and use the jumper wire from the connector on the brown wire to the connector on the green wire, and the gauge should peg to "empty" with the key on.

      John,

      Thanks. I made up a jumper set of wires to connect the dash harness to the gauge which is still out of the dash panel. The car is basically full of fuel and the gauge reacted when I flipped the ignition key. All I need to do not is re-align that needle to "full" and I should be good to go.

      Thanks!!!
