Re: Gas Gauge flutter on a 1946 Packard Clipper Limousine

If you attach a ground wire to the top post on the gauge, it should show full and be steady. One way to check the gauge. Also you could hook a resistor (in series) between zero ohms and 100 to also check the gauge, this would show if the gauge is steady or not, the readings wouldn't really matter. Maybe a 50 ohm resistor would display a half tank, not sure. You would just be looking for movement and that the needle is steady.
With this checkout you can tell the gauge is good and then drop the tank to look at the sender, which is most likely the problem in my opinion.
