Fuel Gauge

The fuel gauge sending unit provides a signal to the instrument cluster that is equivalent to fuel level. With a full tank, sending unit resistance is 90 ohms. With tank empty, sending unit resistance is less than one ohm.

The electronic cluster converts this signal and activates a 16-segment bar graph which displays fuel level. When fuel display bar graph changes from 2 segments to one, an audible alarm sounds and the low fuel warning indicator light comes on.
