Fuel tank wiring

[NathanY]

Can someone tell me how to wire my fuel tank? It has a guage and rocker switch.

Nathan,<br /><br />I don't know why you have the swith.<br /><br />Anyway, the wire from the center post of the sending unit goes to the "S" terminal on the guage.<br /><br />12 volts goes to the "P" or "12V" terminal on the guage. This could come from the switch or the ignition switch.<br /><br />The side terminal on the sending unit is a ground-preferably direct to the battery.

I guess the switch is there to keep the battery from running down. If not the guage will always be on.

Nathan.<br /><br />Probably. You can just as easily wire it into a circuit that is only "live" when the key is on. <br /><br />As an example, if you have a tachometer, there is a terminal "I" on the tach. that is only live with the key on. In that case, the "S" (sender terminal can be wired to that "I" terrminal on the tach.
