Detailed Description

WAI engineers this alternator to deliver the amperage required by today’s vehicle electrical systems while maintaining OE-style fit and function.

What This Alternator Helps Address

• Low charging output or battery warning lights
• Electrical system strain from accessories and vehicle loads
• Charging instability caused by a worn alternator
• Noise or belt issues related to a failing pulley assembly
• Starting problems tied to insufficient alternator output

Installation Notes and Tips

Verify pulley groove count, belt type, rotation direction, and connector style before installation. This unit uses a 7-groove serpentine pulley and clockwise rotation, so matching the original equipment configuration is important for proper fitment. Confirm the vehicle’s charging system requirements and application notes, especially on Mercedes-Benz Sprinter models with Mexico-market fitment and the 2008-2009 R320 note from 2/19/08.

Quality Assurance

WAI builds this alternator as a new replacement unit using proprietary components and manufacturing processes aimed at consistent life and performance. The 11306N is designed for dependable charging output in supported Mercedes-Benz, Dodge, and Jeep applications.
