Fuel Gauge: Description and Operation
How the Circuit Works
The indicator lights are controlled by different conditions in their associated systems.
Fuel Gauge
The fuel gauge has two intersecting coils wound around a permanent magnet rotor. Voltage applied to the coils, through fuse 9, generates a magnetic
field. The magnetic field, controlled by the engine fuel gauge sending unit, causes the rotor to rotate and the gauge needle to move. As the resistance in
the sending unit varies, current through the gauge coils changes, moving the gauge needle toward the coil with the strongest magnetic field.
The fuel gauge sending unit's resistance varies from about 11-13 ohms at Full to 130-132 ohms at Empty. When you turn the ignition switch to LOCK
(0), the gauge remains at the last reading until you turn the ignition switch to ON (II) or START (III).
