Pontiac G6 battery light on despite new alternator, starter, and battery on Pontiac G6

Some Pontiac G6 owners report experiencing a persistent battery light illumination even after replacing the alternator, starter, and battery. This issue can be attributed to several factors, including a faulty alternator that may still be malfunctioning, or a damaged wire within the charging system. Additionally, corrosion on electrical connectors or battery terminals can lead to the battery light remaining on. Some owners also find that a bad ground connection contributes to this problem, while issues with the serpentine belt, such as slipping, can trigger the warning light as well. If the battery light continues to stay illuminated, it is recommended to consult a qualified mechanic or automotive technician for a thorough diagnosis and resolution of the underlying electrical system issues.
