If the gas gauge needle moves to full when the wire from the sender is grounded, the gauge is working. If not the wire to the gauge may be open (broken). You can string a wire from the gauge back to the sender to see if that will remedy the problem. If not, use the wire to check the ground from the battery ground cable at the firewall to the mounting flange of the sender. If you still don't find the trouble, remove the sender from the tank and move the float. You didn't say whether you have an original King-Seely sender or a repro. They operate by different principles. The K-S unit has a bimetal strip that pulses the feed to the gauge, while the repro has a variable resistor that wipes a winding to furnish voltage to the gauge. The gauges in old Fords are very tough, and unless they have been furnished with more than 6 volts, they are seldom at fault.
