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 and the Coolant Temperature Sender. When either of these senders' resistances indicate that a gage is out of the normal operating range, the indicator control circuit grounds the CHECK GAGES indicator, causing it to light.
