Fuel Gauge: Description and Operation
Fuel Gauge
The fuel gauge consists of two intersecting coils wound around a permanent magnet rotor. Applying voltage to the coils through fuse 7 generates a
magnetic field causing the rotor to rotate and the gauge needle to move. The magnetic field is controlled by the sender. As the resistance in the sender
varies, current through the gauge coils changes. The resulting fluctuation in the magnetic field then moves the gauge needle accordingly. The fuel gauge
sender's resistance varies from approximately 17±1 ohms with the fuel tank full, to 120±5 ohms with the tank empty.
