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.

Additionally, the digital regulator in the Generator controls the CHECK GAGES Indicator with a Solid State lamp driver. The lamp driver turns on the indicator whenever an undervoltage, overvoltage or a stopped Generator is detected.
