Then lets see the smart alternator charging on your 2019 Cherokee then, why have all the examples to date been of Wrangler JL'sHey, Tyler is never wrong. Well, actually he thought he was wrong once, but he was mistaken.
Here is a 2021 3.2 Cherokee Trailhawk. Voltage never goes into the 12v range or low 13v range unless it's during an ESS event
I also just did a 2 hour road trip and never saw anything other than 13.9-14.0v so where is this smart alternator charging?
Here is another video showing about a 20 minute drive, but sped up........notice the voltage in the 14's with very little charging current.....totally normal behavior.
