Sending unit

[Data Plate]

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.

Thanks again for the help you just saved me a big job not pulling the gauge out I’ll try the ohms test and see what happens

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?

At this point you are much better off starting a new thread instead of tying onto someone else's month old thread
also give us more information
What car? which dash? what have you done to try to fix it?
The more information we have the easier it will be to help you

I replaced the gas tank and sending unit in my 69 charger and the gas gauge still does work This is what I did before installing the sender I tested it out of the car I put the power wire on it and grounded it I turned the key on and my friend lifted the float slowly up and down the gauge moved up and down in a jumpy way not smooth then I put it in and nothing the gauge didn’t move at all so I bought another sending unit and tried it and it did bathe same thing the ground is good any ideas on what it is

I have a note from National Moparts the fuel sending units sold of late might be/are/were linear, the OEM original sending units were NON-LINEAR.
My posts about fuel gauge issues were about the Autometer 5715, a non-linear gauge. Waiting for more information, this is just a FYI note in case you are having problems.
