Don't Skip This After Upgrading Your Alternator - Big 3 Wiring Upgrade

Upgrading your alternator is only half the job. In this video, I do the full Big 3 wiring upgrade on my 2004 Subaru Forester, running heavy-gauge wire from the alternator to the battery, upgrading the grounds, and installing new battery terminals so this 220A alternator can actually deliver its full potential on the trail. If you're building an overlanding electrical setup, running a diesel heater, fridge, lights, or any camp power off your vehicle, this is the foundation you can't skip.
