Upgrading the alternator in a 2022 Isuzu D-MAX?

Here’s exactly how we installed a high-output 240A alternator and wiring kit into a third-gen D-MAX running the 4JJ3 motor.

In this full step-by-step guide, we show you how to remove the factory alternator, access the belt and tensioner, fit the upgraded unit, and install the custom wiring kit — including the 250A mega fuse and bracket. Everything bolts in with no drilling, and the install retains a clean, factory-look finish.

This setup is ideal for anyone running dual batteries, 12V accessories, winches, or upgraded touring gear that demands more charging power.

🔧What’s covered in this install:
• Removing the OEM alternator and airbox
• Working with the 4JJ3 tensioner setup
• Installing a larger 240A alternator
• Running upgraded cables with a mega fuse
• Heat-shrinking and securing factory wiring
• Mounting the bracket using existing holes
• Achieving a clean, OEM-style finish
