[QUOTE="lavacarancher, post: 1051309, member: 9198"] 84, I've looked at wiring diagrams for several tractors and all of them are as I described earlier. Something is mis-wired. Look at the back of your fuel gauge. There should be only two connections (maybe three if the gauge is lighted). One connection will say "BAT or +" This connection goes to the switched battery somewhere in your tractor wiring. The other connection will be labeled "SEND" or it may not have any labeling. This connection goes to the fuel tank sending unit. You may wind up having to run new wires if you can't figure out where the wires go in the wiring loom of the tractor. Without going into the calculations for determining the gauge sensitivity (in millamps), shunt resistance and sending unit resistance so that the gauge and sending unit are matched I would think that a mis-wire is your culprit. One other thing. Make sure the tank and the sending unit is grounded. There should be an electrical terminal on the flange of the sending unit that has a wire connected to it that goes to the tractor ground. The other electrical connection on the sending unit goes to the gauge. If these two connection are reversed the gauge will respond exactly as you described. PM me if you have any other problems.
