Product Details

This remanufactured alternator is built around the listed electrical and pulley specifications to match the original charging system layout on supported vehicles. The MPA Electrical remanufactured line focuses on service replacement parts for charging and starting systems, and this unit follows the Delco configuration used in the confirmed fitment list. If you are replacing a worn alternator on a 1990-1991 Pontiac Grand Prix, 1988-1991 Buick Skylark, or 1991-1992 Pontiac Grand Am, 7928511 provides the correct 100 amp, 12-volt setup for those applications.
