Sable V6-3.0L VIN U (1999)
Low Fuel Lamp/Indicator: Description and Operation
The conventional instrument cluster contains an instrument cluster gauge amplifier which provides a delay to the fuel gauge/temperature assembly to
prevent the fuel gauge pointer from fluctuating as a result of excessive movement in the fuel tank.
The instrument cluster gauge amplifier has additional circuitry to turn on a LOW FUEL warning indicator when the fuel gauge/temperature assembly
shows approximately 1/16 tank of fuel remaining.
-
The instrument cluster gauge amplifier is designed to prove out the LOW FUEL warning indicator. The instrument cluster gauge amplifier is a
small printed circuit board which latches into a pocket on the back of the instrument cluster.
-
The electrical connections for ignition, ground, input from fuel sender, output to fuel gauge/temperature assembly and low fuel warning output
(where equipped) are made through a spring-type connector on the instrument cluster gauge amplifier to the instrument cluster printed circuit on
the instrument cluster.
-
There are no provisions for calibration or adjustment of the instrument cluster gauge amplifier.
