Ammeter Gauge: Description and Operation

This LED operates independently of the gauge indicator and monitors system voltage. The LED will alert the driver of the following three charging system potential malfunctions:
1. A discharging condition, caused by excessive electrical demand on charging system (engine at idle RPM).
2. A weak or defective battery with ignition switch in On position (before ignition switch is moved to Start position).
3. A weak or defective battery with minimum demand on charging system, while vehicle is being used in stop and go driving (intermittent LED illumination occurring).
