Check Gages Lamp

The Check Gages Lamp lights when either the engine oil pressure is low or the engine coolant temperature is high. The Instrument Cluster's Check Gages Lamp Driver solid state logic monitors the input signals to the Oil Gauge and the Temp Gauge. With the Ignition Switch in the RUN or START position, the Check Gages Lamp Driver grounds the Check Gages lamp when either of the input signals exceeds its setpoint. This causes the lamp to light. The lamp is normally illuminated when the Ignition Switch is placed in the RUN position. It extinguishes when the engine is started and oil pressure increases above setpoint.
