Fuel Gauge Sender: Testing and Inspection
Auxillary Tank Sensor Fault Tracing

-

Remove battery negative lead.

-

Unplug connector and measure with an ohmmeter between the white-gray leads. Resistance should be between 0 Ohm, with auxiliary tank empty,
and 60 Ohm, with auxiliary tank full. 
If resistance reads infinity, measure directly on the sensor terminals.
With resistance other than between 0 and 80 ohm, the sensor is faulty and needs changing.
