Remanufactured Alternator for Mustang

MPA Electrical Part Number 11873 is a remanufactured 12-volt alternator built for Ford Mustang applications that require a 175-amp charging unit. It uses an internal regulator, internal fan, and a 6-groove serpentine clutch pulley for OE-style fitment and charging performance.

Built by MPA Electrical in its Remanufactured product line, this alternator is a practical replacement for Mustang charging-system service where the original Nippondenso-style unit is specified. Part number 11873 is also a direct search match for shoppers comparing Ford Mustang alternator replacement options by amperage and pulley configuration.

What It Helps Address

  • Battery warning lights caused by alternator output loss
  • Low charging voltage during driving or idle
  • Electrical system instability from a failing alternator
  • Accessory performance issues tied to weak charging output
  • Noise or pulley-related wear from a worn charging unit

Installation Notes

Verify the vehicle’s existing alternator matches the 175 amp, Nippondenso-style configuration, 6-groove serpentine clutch pulley, clockwise rotation, and 11:30 clock position before installation. Confirm connector and mounting alignment against the removed unit on the Ford Mustang application listed above. Part number 11873 should be matched to the vehicle’s charging-system specification, especially on 2016-2021 models with the noted alternator type.
