Schematics for the charging system on a 2022 JT

[KG4MXV]

Does anyone have the full dealers service manual, including all schematics and wiring diagrams?

See if this works. I've had it in my Google Drive for a bit. Might be for a 21, can't recall. I have had too many of these trucks, lmao.

Thanks I did find that but it seems to only cover the accessories. I didn't see any of the charging system. As I am looking to install a Aux power system for camping.

Here is the charging schematic

He's got schematics for the Battlestar Galactia.......

Don't forget Battlestar Pegasus

I have schematics for Cylon Basestars, not Battlestars.

These are crazy simple - the output from the alternator pretty much goes right to the high current fuse array at N7. Controlled by PCM using information from the IBS.
That's it, really like any other vehicle from the last 30 years

Whatever you do, don't connect anything directly to the negative battery post - connect only to a chassis ground or the top of the IBS.

Thanks for the heads up. Ya I don't want to by pass the current sensing.

Others have done similar, heck, maybe the same thing, you are going to do so you'll have some help from "those who have done it", I'm sure.

I also wanted to see how the Start stop system was wired as well.
As this is the first vehicle I have owned with it.

The charge controller I am going to use is a Renogy DCC505

It is a really nice bit of kit.
I keeps the vehicles battery charged from the PV input as well as the Secondary (house) battery charged and can support all battery types for the house battery.
Also uses the vehicles charging system to charge the house battery when it either detect charging voltage or a sensing wire is connected to a source that is on during engine use.

In my build it is a 110ah LiFePo4 battery.

The two Jeep batteries are connected in parallel at all times except at the moment of starter activation during an ESS start event.
So whatever one gets, the other gets, whatever load is presented, to a large degree, both handle that load.
