Detailed Description

This remanufactured alternator is engineered for vehicles that use a Bosch 120 amp unit with a 6-groove serpentine pulley and clockwise rotation. It cross-references Bosch-style and OE replacement numbers used across Chrysler Crossfire and Mercedes-Benz C240, C320, CLK320, ML320, ML350, SLK320, C230, and C32 AMG applications. This part cross-references BBB Industries 13884 and Valeo 439298 for the same application.

Use MPA Electrical 13884 when replacing a worn charging unit on 2004-2008 Chrysler Crossfire, 2001-2005 Mercedes-Benz C240 and C320, 2003-2005 Mercedes-Benz ML350, and other listed Bosch-equipped models. The remanufactured construction supports direct-fit service where the original alternator matches the listed amperage, pulley, and regulator configuration.

What It Helps Resolve

• Low battery charge or repeated battery drain
• Charging warning light on the dash
• Weak electrical output at idle or under load
• Alternator bearing or internal regulator failure
• Charging system noise or inconsistent voltage output

Installation Notes and Tips

Verify the existing alternator matches the Bosch 120 amp specification, 12-volt system, clockwise rotation, and 6-groove serpentine pulley before installation. Confirm vehicle application by year, make, model, and engine/charging-system configuration, especially on Mercedes-Benz C240, C320, CLK320, ML320, ML350, SLK320, C230, and C32 AMG listings. Inspect the belt condition, pulley alignment, and charging connectors during replacement to help ensure proper operation.
