MPA Electrical 7273106 Alternator

Remanufactured 78 Amp Alternator

MPA Electrical Part Number 7273106 is a remanufactured 12-volt alternator built for Delco applications that call for a 78 amp output, internal regulator, external fan, and clockwise rotation. It uses a 1-groove V-belt pulley and a 6:00 clock position, making it a direct-match replacement for many GM cars from the early to mid-1980s.

Compatible With Buick Skyhawk, Chevrolet Camaro, Pontiac Firebird, and other listed Buick, Chevrolet, Oldsmobile, and Pontiac applications, this alternator supports vehicles with and without air conditioning depending on the exact fitment notes. Part number 7273106 is also cross-referenced to 7273-6 for the same application.

Detailed Fitment and Application

This remanufactured alternator is built around the specifications commonly used on GM rear-wheel-drive and compact platforms from 1981-1986. It fits applications such as 1984-1986 Buick Skyhawk, 1985-1986 Chevrolet Camaro, 1985-1986 Pontiac Firebird, 1984-1985 Buick LeSabre, 1984-1985 Chevrolet Caprice, 1983-1985 Chevrolet Impala, 1984-1985 Oldsmobile Delta 88, and 1981-1985 Pontiac Parisienne, along with additional listed Buick, Chevrolet, Oldsmobile, and Pontiac models. The 6:00 alternator plug and 78 amp capacity are important identifiers for matching the correct charging system configuration.

What This Alternator Helps Solve

• Low charging output or battery drain caused by a failing alternator
• Dim lights or unstable electrical performance at idle and cruise
• Charging-system warning lights related to worn internal components
• Fitment issues when replacing a Delco-style 78 amp alternator with 6:00 plug clocking
• Restoration needs for original-style Buick, Chevrolet, Oldsmobile, and Pontiac charging systems

Installation Notes and Tips

Verify the vehicle’s air conditioning configuration, regulator plug position, pulley style, and alternator clocking before installation. This unit uses a 1-groove V-belt pulley and clockwise rotation, so belt alignment and bracket compatibility should be checked against the original part. Confirm the application against the vehicle’s charging-system specifications, especially on 1983-1986 Camaro and Firebird models where engine and A/C notes affect fitment.

Quality Assurance

MPA Electrical supplies this part as a remanufactured alternator built to match the listed Delco-style application requirements. Part number 7273106 is intended for direct replacement use where the original charging system calls for a 78 amp, 12-volt alternator with internal regulation.
