Hey Chuck - okay, I'm all fixed. Yep, the step-down 24V to 12V Victron Orion converters were toast. Something must've shorted and sent a surge to them and they were done. Just replaced both and wired them independently with separate 100A leads and we're back in business. The old converter under the bed, albeit inefficiently so, did the job while I waited for parts.
Here is how my 12V system was modified when my installer merged battery banks.
1. Ran one 12V positive lead from the bus energized from my new converters, directly to the front of the coach where the old 6V bank of inverter batteries were and connected it to a 12V starter battery for my generator. He kept the wiring attached to the Main IRD relay also on that battery post which is why that battery picked up the 12V load from the converters.
2. He disconnected all the 12V connections to the old inverter in the front driver's bay.
3. He ran the other 12V lead from the bus energized from my new converters, back to the driver's side battery bay and connected it to the 12V positive leads that were attached to the old coach batteries there. One of those leads connects to the input side of the Coach Disconnect solenoid thus energizing the 12V system from my new converters. Thankfully but likely unintentionally, he also attached the lead from the old converter which allowed me to use it.
I'm going to update the drawing to show folks how it all works. Unfortunately, the laptop that I was using died and we lost the drawings I had previously done. I have copies but will just need to redo them. Thanks again for all the help and wisdom on this one.
