Detailed Description
This remanufactured alternator is built for direct replacement in Mercedes-Benz E320 charging systems from 1994 through 1996. Part Number 15977 is intended for buyers who need a replacement alternator with the correct electrical output, mounting configuration, and internal regulation for the listed vehicle application. This part cross-references 009-154-43-02 and 19135063 for the same application.
Compatible with 1994-1996 Mercedes-Benz E320, N/A. The OE-style remanufacturing process is used to restore core functionality and verify performance before release, helping maintain proper battery charging and electrical system operation in the vehicle.
What It Helps Address
- Battery warning light caused by alternator output loss
- Low charging voltage at the battery
- Dim lights or unstable electrical performance
- Charging-system failure on Mercedes-Benz E320 models
- Noise or wear related to a failing alternator assembly
Installation Notes and Tips
Verify the plug clock position, rotation direction, amperage rating, and pulley configuration before installation. This unit does not include a pulley, so the existing pulley setup must match the application requirements. Confirm the vehicle is a 1994-1996 Mercedes-Benz E320 and compare the original unit to Part Number 15977 before replacement.
