BBB Industries 11793 Alternator

Reman Alternator for Ram ProMaster 1500-3500

BBB Industries REMAN ALTERNATOR 11793 is a 12-volt charging system replacement built for select Ram ProMaster vans with a 220-amp output. It uses an external voltage regulator, clockwise rotation, and a serpentine pulley setup to match the listed OE-style application.

Compatible with 2014-2021 Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 applications, this remanufactured alternator is configured with a Nippondenso OE manufacturer reference, internal fan, air cooling, and a decoupler pulley. Part number 11793 is also cross-referenced to 421000-7110 and 4727756AA for the same application.

Key Features

• 220-amp amperage rating for high electrical demand
• 12-volt remanufactured alternator
• External voltage regulator type
• Clockwise rotation with 6-groove serpentine pulley
• Decoupled clutch pulley included
• Internal fan and air-cooled design
• Negative polarity configuration
• 3 o’clock plug clock position
• OE manufacturer reference: Nippondenso

Detailed Description

BBB Industries 11793 is a reman alternator engineered around the listed OE configuration for Ram ProMaster charging system service. The 220-amp output supports vehicles with elevated electrical loads, while the included decoupler pulley and serpentine belt interface help maintain proper belt drive operation. The unit’s external regulator setup, negative polarity, and 3 o’clock connector position are important match points when replacing the original alternator.

This part number 11793 is a direct-fit style replacement for 2014-2021 Ram ProMaster 1500, 2500, and 3500 models listed in the fitment data. It is also referenced by 421000-7110 and 4727756AA for the same application.

What It Helps Address

• Low charging voltage at the battery
• Battery warning light or charging system fault codes
• Dim lights or unstable electrical performance
• Alternator bearing or pulley-related noise
• Charging failure after alternator wear or internal component breakdown

Installation Notes and Tips

Verify the 220-amp rating, pulley type, plug clock position, rotation direction, and external regulator configuration before installation. Confirm belt alignment, pulley groove count, and connector fitment against the removed unit to ensure the Ram ProMaster 1500, Ram ProMaster 2500, or Ram ProMaster 3500 application matches the vehicle.

Because this alternator uses a decoupler pulley and serpentine belt drive, inspect the belt, tensioner, and related drive components during replacement. Confirm the OE-style electrical connections and mounting points match the original part number 11793 application.

Quality Assurance

BBB Industries remanufactured electrical components are built to meet the listed application requirements and OE-style specifications for the vehicle platform. This reman alternator is produced to align with the original Nippondenso-based configuration used on the specified Ram ProMaster models.
