Re: The gas gage wire

The center wire is neither, it is the sender wire. It reads resistance in relation to ground. As your float changes positions, the resistance readings change, reflected in your gauge readings. There is no 12+ going to your senders. There IS a 12V+ going to your gauge, as the gauge needs power to operate. The switch on your dash simply allows you to switch back and forth between tanks to see what quantity of fuel you have in each tank.

Check for voltage on the gauge (the wire connected to the "I" terminal), and check your grounds all the way through...both senders, and the gauge.
