  • Cool/Heat: Temp gauge

    I have a 53 commander that has been changed over to 12 volts.......the temp gauge reads cold when the key is turned on....after the engine starts and warms up, it slowly moves to the normal range...looks like everything is ok...then it goes to full hot and remains there......I put in a new 6v sensor....if you pull the sensor wire and ans turnon the key...the voltage at the wire is 3.2 volts...????

    Is the power wire from the Ignition switch to the dash unit 12V or 6V?

    Are you pulling the dash end of the sender wire or the sender end?

    The wire to the dash unit only gives varing RESISTENCE to GROUND depending on the temp. of the Coolant.

    It should not carry Voltage.

        You have probably already burned out the gauge. If not, put on a regulator. You can use a Runtz from 5th avenue or one from these guys

        You need one for the temp gauge and one for the fuel gauge.
