FIXED. It was one of the two for me below
Possibility 1
A stuck Intellisec BCC Relay. (Part 01-00055-00232798). There were two behind the Board by the batteries. I learned how to zap them open and close using a KZEEE KM10 (supplies 12v poles from battery). I disconnect coach and chassis batteries (for safety since I wasnt 100% what I was doing) and then zapped them to closed position. I started it up and it cranked
I had read from someone else that posted similar process and believes they may have 'unstuck' the relay by giving it juice. However, not fully convinced this was it....
Possibility 2
User Error/Newness to the American Coach
While I had the BCC relay in front of me with disconnected batteries, I connected a wire toner (two piece gadget that helps you find wires via a tone wand) to the wire that zaps the BCC relay and had my wife find where it goes to the coach. Next to the slide control inside the cabinet was a battery disconnect that read AUX and MAIN (above it was the solar meter). This is where the buttons are to turn those relay on and off manually. It threw me off because everything I read calls these batteries Chassi/Motor, or House/Coach. After it started I then turned off the coach and played with these buttons and I was able to replicate the no crank no start. I may have turned those off while showing the coach to fam (or someone in fam did) because I thought those were related to the solar charging.
Finally, I'm leaning towards possibility 2 being my real issue because there was a key datapoint that kept getting overlooked when I was asking community for help (multiple forums). The coach not cranking, the generator not cranking, and the AUX Start not working anymore (all at the same time) all point to those two AUX and Main disconnect buttons. I'm happy it happened though because I was forced to learn a lot more about my coach than I expected to only three weeks in. I also feel that the battery tenders didn't do anything wrong and worked as expected, I went down a bunny trail because I thought i fried something. But now that I know what I know, the system is not really that complex from a regular vehicle. Still glad it all happened though. l feel better prepared for the road now given three weeks in to having my first motorcoach. Thanks to all the chimed in!
