Redoing the 12v on a 93. Anyone have the diagram?

[dbhosttexas]

Just wondering if anyone has the diagram / manual pages for the 12v system on a 93 Sportsmobile. I know the house battery is charged via the battery isolator under the hood, I was expecting to find that behind the battery on the drivers side, but nope. It is behind the passenger side headlight and is MUCH larger than I expected. Wiring between there and the electrical compartment should already be 8 gauge, and have the 50 amp breaker in line, so I just need to bypass the isolator, and whatever the cable attaches to in the electrical compartment, set it up for the Anderson connector for my DC to DC charger DC charging circuit (It is also an MPPT controller.

I also need to see how this ties into the 12v output side of things. I eed to tie my new battery bank into the 12v output.

I see the fuse panel on mine, but it looks like there is very little there, maybe 3 fuses populated. I suspect I will be tracing wires, and it is still hot in Texas unless I pop the top, open all the doors and windows it is just intolerable inside the van...

FWIW, I am trying to integrate the following.

2 @ Dokio 300w portable panels via a custom Anderson connected Y cable.
2 @ Chins 200 amp hour 12v Lifepo4 batteries.
AtemPower 40 amp DC to DC charger / MPPT controller, latest version wtih LifePo4 charging profile.

I also need to determine the capacity of the installed inverter, and swap that out for a pure sine wave inverter to protect my laptop and such...

You can find three SMB manuals here Sportsmobile Manuals. The 1998 version would be the closest to your 1993. The electrical drawing are limited, but you can get the general layout from them.

That is exactly what I needed. And yes the 110v / 12v sheets look like what I had seen in a 1994 manual but lost it...

FWIW, I am planning on pulling out the OE converter / battery charger, battery isolator and inverter. Well at least Sportsmobile recommends replacing the inverter. Anyway you see my parts list above. The questions I have left are...

It looks like the 110v converter / battery charger serves the sole purpose of charging the battery from shore power. It is older tech so will not work with Lifepo4 batteries. What should I use to replace it?

Do I really need to replace the original inverter, which is possible but not sure, and if so what specs should I look for?

Lastly, the little, lamp thing a ma bobs by the captains chairs and the dinette, the plastic is falling apart on them and, well they gotta go. What would I need to watch out for if I wanted to say go with some kind of 12V LED light / fan fixtures? I would love to be able to have some more fans in there moving the air around... ESPECIALLY by the dinette / bunk as I sleep with a ceiling fan on...
