Detailed Description

MPA Electrical part number 13030 is a remanufactured alternator engineered for vehicles that use a Bosch-style charging system with external regulation. The unit is configured for clockwise rotation and does not include a decoupled or clutch pulley, making it a straightforward replacement for the original charging component when the existing mounting and electrical setup match the application. This alternator is listed for Porsche 914 applications, along with Volkswagen Transporter, Volkswagen 412, and Volkswagen 411 fitments.

Remanufacturing and testing technology are used to verify the alternator’s OE replacement characteristics before it is released for service. For buyers searching for a remanufactured alternator for Porsche 914 or a Volkswagen Transporter charging system replacement, part number 13030 provides a specification-matched option based on the listed fitment and electrical attributes. This part cross-references Monroe Shocks & Struts (e.g., 021-903-023, 022-903-022) for the same application.

What It Is Used For

  • Replacing a worn or failed charging unit
  • Restoring battery charging output
  • Addressing low-voltage charging system conditions
  • Correcting alternator noise or charging instability
  • Matching an external-regulator charging setup

Installation Notes and Tips

Verify the vehicle’s charging system uses a 12-volt, external-regulator alternator with clockwise rotation before installation. Confirm the plug orientation, mounting ear position, and pulley requirements against the original unit. Fitment includes Porsche 914, Volkswagen Transporter, Volkswagen 412, and Volkswagen 411 applications; part number 13030 should be matched to the existing electrical and mounting configuration.
