72 TA : New Project

[njsteve]

I fixed the gauge problem. An old-time mechanic buddy of mine gave me this secret: if you want to verify if the guage is working disconnect the temp sensor wire from the sensor at the engine and connect a test light between the sensor wire and engine ground. Turn on the ignition switch. The test light should glow dimly. If it glows, the gauge is working and is grounded properly and the sensor itself is bad. That was the case here. I went to the local NAPA store and they actually had the correct gauge sensor in stock with the correct slip-on style terminal end for early GM vehicles. This makes me happy as I did not want to pull the dash out for exploratory surgery.
