BBB Industries 7771-P57 Alternator

Reman Alternator for Ford 3G Applications

BBB Industries REMAN ALTERNATOR 7771-P57 is a 12-volt, 130-amp alternator built for Ford charging-system applications that use a serpentine belt drive. It features an internal voltage regulator, internal fan, clockwise rotation, and a conventional pulley to match the original equipment layout on supported vehicles.

This remanufactured alternator is a direct-fit electrical replacement for select Ford Mustang, Ford Thunderbird, and Mercury Cougar models. The BBB Industries reman alternator line focuses on OE-style replacement coverage for charging-system service, and 7771-P57 follows the 3G series configuration used in these applications.

Detailed Description

BBB Industries 7771-P57 is a reman alternator engineered for Ford charging systems that require a 130-amp, 12-volt unit with an internal regulator and a 6-groove serpentine pulley. The plug clock position is 11, and the unit uses a conventional pulley design with standard clockwise rotation. As a 3G-series alternator, it matches the electrical and mounting characteristics used in the listed Ford and Mercury applications.

Use 7771-P57 when servicing charging output concerns on 1994-2000 Ford Mustang, 1994-1997 Ford Thunderbird, and 1994-1997 Mercury Cougar models. This part number, 7771-P57, is also a useful reference when comparing OE-style replacement options for these vehicles.

This part cross-references Ford service numbers F4PU-10346-BA and F4PZ-10346-B for the same application.

What It Helps Solve

• Low battery charging caused by alternator output loss
• Battery warning light concerns related to charging-system faults
• Dim lights or electrical instability from insufficient amperage
• Noise or wear issues tied to a failing alternator pulley or internal components
• Starting problems caused by weak charging performance

Installation Notes and Tips

• Verify pulley groove count, plug clock position, and rotation direction before installation.
• Confirm the vehicle uses a serpentine belt drive and the correct 3G-series alternator configuration.
• Inspect the belt, tensioner, and charging cables during replacement to avoid repeat failures.
• Check battery condition and system voltage after installation to confirm proper charging output.

Quality Assurance

BBB Industries remanufactured electrical components are built for OE-style replacement service and application-specific fitment. Part number 7771-P57 is matched to the listed Ford Mustang, Ford Thunderbird, and Mercury Cougar applications for charging-system repair.
