Installed new 12v gauge and it seems to be stuck at 3/4 tank. Unhooked wires from sending unit and it stays on 3/4. Am I wired wrong? | | | | | Joined: Sep 2001 Posts: 29,270 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,270 | "Unhooked wires from sending unit . . .[/b] . . . "
Do you have more than one wire from the tank sending unit to the gauge?
Did the new 12v gauge indicate the ohm rating for the sending unit? | | | | | Joined: Mar 2009 Posts: 10 'Bolter | | 'Bolter Joined: Mar 2009 Posts: 10 | One wire to gauge and one ground. Don't know the ohm rating. New gauge but sending unit was in when it was still 6 v

Which post did you wire to ignition switch?
Gauges do not like it when you do it backwards. Ignition switch wire goes to the "E" (empty) post.
