Detailed Description

MPA Electrical 8137611N is an alternator for GM passenger cars that require a Delco-style unit with a 105 amp rating and 12-volt operation. The 11:00 clock plug position is important for proper connector alignment, especially on second-production 1992 Buick Century, Oldsmobile Cutlass Ciera, and Oldsmobile Cutlass Cruiser applications. This part cross-references BBB Industries 8137-11 for the same application.

Use this alternator when replacing a worn charging unit on a 1992-1993 Oldsmobile Achieva, 1992-1993 Pontiac Grand Am, or the listed Buick and Oldsmobile models. The part number 8137611N is also associated with interchange references including 1101642 and 10463369.

What It Helps Address

• Battery warning light caused by alternator output loss
• Low charging voltage during driving
• Dim lights or electrical instability
• Charging system noise from a failing alternator
• Connector or pulley mismatch on the original unit

Installation Notes and Tips

Confirm the vehicle uses a 105 amp alternator and verify the 11:00 plug orientation before installation. Match the 6-groove serpentine pulley, clockwise rotation, and internal regulator configuration to the original unit. On 1992 second-production vehicles, the plug position is a key identifier for correct fitment. The MPA Electrical 8137611N should be compared against the original alternator tag and connector layout before removal.

Quality Assurance

MPA Electrical supplies this alternator as a new replacement component built to the listed Delco specification and fitment profile for the covered Buick, Oldsmobile, and Pontiac applications.
