You may be interested in Bob's latest dual alternator configuration Z101
. He seems to be moving on from Z12. I think the latest thinking is with two reliable alternators an endurance bus is not needed.
Z101 shows an engine bus for an all electric ignition system. Just cut that part out if you using mags/Pmags or ShureFly.
I thought I wanted dual alternators when first planning my electrical system but realized with a TCW IBBS back up battery I didn't need the expense and complexity of two alternators. Here's my system
which is a cut down version of Z101
