Fuel Gauge

First post and it's a question, Hope that's OK. I have a 96 F350 CC and if the fuel gauge does not have power, the needle sits right on "E", when it gets power (key on), it goes Below "E"? I have checked the connections and cleaned them and used dielectric grease on the connections. I have also checked the harness to the firewall but I'm not sure I'm heading in the right direction. I have the new brass floats, but I figured I would check around before. Thanks.

Re: Fuel Gauge

You have a dead short to ground on the wire from the sensor to the gauge. That will make the needle move mast the normal position.
A pure open circuit on the sensor will make it go waaaaaayy past full. I've got a pic in my album somewhere.

Re: Fuel Gauge

Either that or the gauge is hooked up backwards.

Re: Fuel Gauge

The sender wire is connected to ground somewhere. It won't burn the wire because the sender reduces the voltage enough. Backwards coud be fuel + to panel ground. Has the instrument panel connector been rewired?
