I was gonna pull the cluster out and change the gauge but you think the gauge is ok? So it’s suppose to go up in clicks?
Not necessarily clicks, but it's not instant. Also.. how well charged is your battery. Put a charger on it and test again since you're doing this with the car not running. The main thing is you now know it is NOT the gauge that is your issue. It's your sending unit. Check for continuity between frame/body and sending unit face. If zero ohms then your ground is fine and it's the rheostat or the float has sunk.
none of my gauges are working not the fuel alt oil or temp. New sending unit in the tank car is a 65 coronet 440 and the black wire going to the cluster from the switch is hot but nothing else. Any ideas?
