BBB Industries N7791 Alternator

BBB Industries N7791 Alternator for Ford Applications

BBB Industries N7791 is a new 12-volt alternator built for Ford charging-system applications that call for a 130 amp output. It uses an internal voltage regulator, clockwise rotation, and a conventional pulley with an 8-groove serpentine belt interface for OE-style replacement fitment.

Key Features

• 130 amp amperage rating for factory-style charging output
• 12V alternator with internal voltage regulator
• 3G series design with internal fan and air cooling
• Conventional pulley included, 8-groove serpentine belt type
• Clockwise rotation with negative polarity
• 10 o’clock plug clock position for OE-style electrical connection
• OE manufacturer reference: Ford

Product Details

The BBB Industries NEW ALTERNATOR line focuses on replacement charging components built around OE-style specifications. Part number N7791 is a Ford alternator application with a 130 amp rating, internal regulation, and a pulley setup matched to serpentine belt systems. The 3G series configuration, internal fan, and air-cooled housing support factory-style operation in vehicles that originally used this charging system. This part cross-references Ford service numbers such as F7PU-10346-KA and F7PZ-10346-KA for the same application.

Common Uses

• Restores charging output on a Ford F-150 with a failing alternator
• Addresses battery warning lights caused by low alternator output
• Helps correct dim lights or electrical instability at idle
• Replaces worn OE alternators in Expedition, Econoline, and Navigator applications
• Supports proper battery charging after alternator bearing or regulator wear

Installation Notes and Tips

Verify pulley groove count, plug clock position, rotation direction, and amperage rating before installation. Confirm the vehicle uses the 3G-style alternator configuration and an 8-groove serpentine belt setup. Inspect the belt, battery condition, and charging connections during replacement to avoid repeat charging-system faults. Use the vehicle’s original mounting and electrical layout as the reference for fitment on Ford F-150, Econoline, Expedition, F-250, and Lincoln Navigator applications.
