Fuel Gauge: Description and Operation
CIRCUIT OPERATION
A potentiometer is built into the fuel sender assembly. When the fuel tank is full, the resistance throughout the potentiometer is approximately 88
ohms, and at empty, the resistance is approximately 1.0 ohms. The fuel gauge applies voltage through CKT 30 to the potentiometer. As the resistance
of the potentiometer decreases, the fuel gauge senses a smaller voltage drop across the potentiometer, indicating a lower fuel level. As the resistance
of the potentiometer increases, the fuel gauge senses a larger voltage drop across the potentiometer, indicating a higher fuel level.
