Detailed Description

MPA Electrical 11929 is a remanufactured alternator engineered for OE-style replacement in the Fiat 124 Spider. It is built around a Nippondenso-style design with internal regulation, internal cooling fan construction, and a serpentine belt pulley to match the original charging system layout. The 150-amp rating supports vehicles that require higher charging output while maintaining factory-style fitment and electrical connections.

This part fits 2017-2020 Fiat 124 Spider models and is intended for direct replacement service where the original alternator has failed or is no longer maintaining proper system voltage. Part number 11929 is also associated with OE cross-reference numbers 4727 796AA and 51884239 for the same application.

What It Helps Solve

  • Battery warning light caused by alternator output loss
  • Low charging voltage during driving
  • Dim lights or unstable electrical performance
  • Battery drain after the engine is running
  • Noise or pulley-related charging system issues

Installation Notes and Tips

Verify pulley alignment, connector orientation, and mounting ear position before installation. Confirm the vehicle uses the listed 12-volt charging system and compare the original unit’s plug clocking, rotation direction, and pulley style to part number 11929. Inspect the belt condition and charging circuit connections during replacement to help avoid repeat failures.
