Check Gages Indicator
The CHECK GAGES Indicator, located in the Instrument Cluster, is controlled by a Solid State buffer located in the Auxiliary Gages Assembly. This buffer receives inputs from the Fuel Pump/Oil Pressure Switch/Sender, Coolant Temperature Sender, Fuel Level Sender and the Generator. When any of these components indicate that a gage is out of the normal operating range, the indicator control circuit grounds the CHECK GAGES indicator, causing it to light.
