I spent an enormous amount of time pouring over the Aeroelectric Connection book and associated diagrams. The closest diagram to what i wanted to achieve is Z-19 pictured below. This is the basis of my primary power system architecture. Some other choices I made. I have a B&C Alternator which means i have their external voltage regulator. I wanted to uses fuse buses not circuit breakers. I wanted to have two batteries and one alternator, not the other way around.
I used hefty diodes to isolate my main and aux battery and associated busses.
Here is my hand drawing of my primary power system modified to my needs from the Z-19. I plan to get this put in electronic format at some point in time.
