Wilson 90-04-7105 Remanufactured Alternator

The Wilson 90-04-7105 is a remanufactured 12-volt alternator built for charging-system repair where output and OE-style fitment matter. With a 270-amp rating, pad mount design, and IR/EF configuration, it is suited for heavy electrical demand in commercial and equipment applications.

Key Features

• 270 amps for high-output charging performance
• 12-volt electrical system application
• IR/EF design with pad mount configuration
• Clocking: 4:30 Bat Term
• Remanufactured to meet and exceed OE specifications through teardown, cleaning, reassembly, and testing
• Unit OE: LEECE NEVILLE (PRESTOLITE)

Product Line Details

Wilson Remanufactured Alternators are processed beyond a basic rebuild. Each unit is fully disassembled, cleaned, rebuilt with components selected to Wilson standards, and tested before release. That approach supports dependable charging performance for vehicles and equipment that need consistent uptime.

This part number, 90-04-7105, is a direct replacement option for applications that call for the Wilson 4900 series alternator. It also cross-references 4944PA for the same application.

What It Helps Solve

• Low battery charging caused by a weak alternator
• Dim lights or electrical instability under load
• Charging-system warning lights
• Reduced output in high-demand electrical systems
• Alternator failure on equipment using a LEECE NEVILLE (PRESTOLITE) OE unit

Installation Notes and Tips

Verify the mounting style, clocking, amperage, and terminal orientation before installation. Confirm the pad mount layout and 4:30 battery terminal position match the original unit. For fitment-based searches, this alternator is the type of replacement commonly sought for Wilson alternator 90-04-7105 applications and LEECE NEVILLE (PRESTOLITE) OE-equivalent charging systems.

Quality Assurance

Wilson remanufactures this alternator through a controlled process that includes teardown, cleaning, reassembly with components built to Wilson standards, and rigorous testing to meet and exceed OE specifications.
