What It Helps Resolve

• Battery warning light caused by alternator output loss
• Low charging voltage in the electrical system
• Dim lights or unstable electrical performance
• Battery drain after driving
• Charging failure on Mercedes-Benz CL600 and S600 vehicles

Installation Notes and Tips

Verify the plug clock, mounting ear orientation, pulley configuration, and rotation direction before installation. Confirm the vehicle uses a 12-volt, 150-amp alternator with a 7-groove serpentine belt drive and liquid-cooled Bosch-family layout. Compare the original unit to MPA Electrical Part Number 13975 to ensure the connector and mounting points match the factory arrangement.
