BBB Industries 13859 Alternator

Remanufactured Alternator for Toyota Trucks

BBB Industries REMAN ALTERNATOR 13859 is a 12-volt, 100-amp replacement alternator built for select Toyota truck applications. It uses an internal voltage regulator, clockwise rotation, and a serpentine-belt pulley setup to match the original charging system layout on covered vehicles.

Compatible with 2001-2002 Toyota Sequoia and 2000-2002 Toyota Tundra applications, this remanufactured alternator is a direct-fit charging component for vehicles originally equipped with a Nippondenso-style unit. Part number 13859 is also referenced for OE-style replacement needs where the original alternator uses a 12 o’clock plug position and a 6-groove pulley.

Key Features

• 100-amp output for factory-style charging performance
• 12-volt alternator with internal voltage regulator
• Serpentine belt drive with 6-groove conventional pulley included
• Air-cooled design with internal fan
• Clockwise rotation and negative polarity
• OE manufacturer reference: Nippondenso
• BBB Industries REMAN ALTERNATOR line for remanufactured electrical replacement parts

Detailed Description

BBB Industries 13859 is a remanufactured alternator engineered around the original charging-system specifications used on select Toyota Sequoia and Toyota Tundra models. The unit is rated at 100 amps and features an internal regulator, internal fan, and air cooling to support stable electrical output in normal vehicle operation. The included pulley is a conventional 6-groove design sized at 2-1/2 inches outside diameter, and the plug clock position is 12 o’clock for proper connector alignment.

This part cross-references OE-style applications associated with Nippondenso alternators and is listed for Toyota Sequoia and Toyota Tundra fitments where the vehicle was equipped with a 100-amp charging system. Part number 13859 is a practical replacement choice when the original alternator matches the listed electrical and mounting specifications.

What It Helps Address

• Battery warning light caused by alternator output loss
• Low charging voltage at idle or under electrical load
• Dim lights or unstable accessory performance
• Charging-system noise related to a worn alternator assembly
• Failure of the original Toyota Sequoia or Toyota Tundra alternator

Installation Notes and Tips

Verify the vehicle’s original amperage rating, pulley style, connector orientation, and rotation direction before installation. This alternator is not one-wire capable and uses a serpentine belt with a conventional pulley, so the existing charging-system configuration should match the listed specifications. Confirm fitment for 2001-2002 Toyota Sequoia and 2000-2002 Toyota Tundra before replacement.

Quality Assurance

BBB Industries remanufactured electrical components are rebuilt to meet application-specific replacement requirements for covered vehicles. This REMAN ALTERNATOR 13859 is specified for direct replacement use on the listed Toyota applications.
