1997 Four Winds Hurricane 30Q Need wiring diagrams or advice for the 12v power box

I recently purchased a 1997 Thor Four Winds Hurricane 30Q motorhome that has had some electrical work done to the power distribution center. I would love to find a new circuit board as mine has been repaired but since that's out of the question I would like to wire it as close to original as I can to get as many systems working on my rv before i take it cross country. I mainly need to know how to wire the isolator/solenoids in the center. There's a picture on it but it doesn't show some of the wires and how they are connected and if they are connected to each other or not. If someone has an original wiring diagram or can show me a properly wired distribution center I would greatly appreciate it.

It would be easier to start with a new power center from WFCO, PPS or PD than try to fix a 20 year old electrical system.

The attached PDF is for something a few years newer but might help with the overall theory of operation regarding the disconnect solenoids.

Sweetbriar, that was helpful and confirmed what I was seeing on other similar setups. I did see a picture of another power center like mine who also had problems but I think his board and battery disconnects were correct. This is what I ended up with. I used the continuous duty solenoids for both but I think I might change the coach battery side to a latching solenoid as it may get hot if itís always in use.

You would be better served with latching solenoids. Save a bit of power when dry camping plus they will run cooler and probably last longer. Try and get 200 amp rated contract. Higher would be better. You may never need that many DC amps for normal usage but good have just in case.

And to give you an idea what's available - https://www.intellitec.com/
