Fuel Gauge Module: Description and Operation
Instrument Cluster Gauge Amplifier/Check Gauge Module
The instrument cluster gauge amplifier electrically averages fuel sender readings so the fuel gauge displays actual fuel level and not fluctuations due to
sloshing in fuel tank. 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 and output to fuel gauge 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.
