Fuel gage issues

I have an 87 ram and the gas gage didn't move. I pulled the bed and found a bad connector to the sender. i replaced the connector and now the gage pegs full. I also put an ohm meter across the sender and it read .42 ohms which could be right since there is close to a half a tank of gas.
The wires read ground so now I'm stuck.
Does someone have any insight?

Doc here,

Be sure you have a proper tank ground..

On the gauge, On an 87, not sure they were still using them, but older gauges were operated by a 5 volt regulator, check to see if you have that, and that it is regulating at 5 volts..

Remove the sender wire, The gauge should peg one way, then ground it, It should peg the other, If you can do that the gauge and circuit is in tact..Check your sender for worn condition...or just replace it..

It could also be stuck on something , not changing the value on the gauge..you won't know until you pull and inspect it.
