Product Details

Denso reman alternators are processed through testing and refurbishment steps that verify electrical integrity and mechanical condition before release. Stators and rectifiers are tested to 300 volts, rotors to 600 volts, and rotor slip rings are finished to a fine surface to reduce brush wear. Bearings are validated to OE standards and lubricated with premium OE-grade grease. For Ford Edge owners, part number 210-4221 provides an OE-style charging solution for 2012, 2013, 2014, and 2015 models with the listed 150 amp application.

This part cross-references BBB Industries 11550 and Remy 23000 for the same application.

Common Charging System Issues

• Battery warning light caused by low alternator output

• Noise from worn bearings or rotor-related wear
• Poor fitment from a replacement alternator that does not match OE mounting points

Installation Notes

Verify the vehicle’s charging system specifications before installation, including voltage, amperage rating, rotation direction, and regulator type. Confirm fitment for 2012-2015 Ford Edge, N/A, and compare the original unit to part number 210-4221 before removal.
