57 Gas gage always reads full when ignition is on

[Bill Balkie 24172]

Hello,
   M fuel gage reads full when the ignition is turned on .It is pinned to the full position .  empty when the ignition is turned off . i did check the ground and it looks OK . I disconnected the sender wire and the situation is still the same , reads full . The gage worked OK up until last week . Any thoughts on this would be greatly appreciated .

  Thanks,
      Bill

That usually means a break in the sender to gauge supply wire Bill, mine doesn't work and is always on empty meaning complete ground, if I disconnect the wire it reads full meaning no ground. You need to make sure the wire is OK all the way to the sender, it could be broken of the unit itself if your lucky.

   My fuel gage reads full when the ignition is turned on.  It is pinned to the full position.  Empty
when the ignition is turned off.  I did check the ground and it looks OK.  I disconnected the sender
wire and the situation is still the same, reads full. The gage worked OK up until last week. Any
thoughts on this would be greatly appreciated .
