Ah, I forgot about that one.

Krea I would be interested in seeing the solution you come up with for the injectors in particular. I had difficulty resolving that problem without introducing a level of complexity that made the overall system more complex and less reliable. For me at least there was no free lunch. The way I set up mine the only real danger is the unlikely event of shorting the entire to bus to ground, a risk that easily can be mitigated.
.....a small "injector bus" fed by both aircraft busses through Schottky diodes.......
I may be misunderstanding and I thought of this as well but if either bus shorted it would still take out the injector bus. If that is the case, haven’t accomplished anything other than doubling the risk of taking the whole bus down and added extra weight, complexity, and cost. That’s how I’m reading it.
What is your preferred solution?
If you are using the EFII system, you may want to do a bit of research...the stated ECU logic and fuel pump logic may not be what you think...
Also note coil configuration is different for six-cylinder engines SDS versus EFII. SDS uses two six-cylinder coils whereas EFII uses three four-cylinder coils.
I'm leaning towards contactors/relays for the engine bus feed. The standard Spruce-supplied contactor sucks a lot of power to stay on, so I'm looking at some sealed industrial units or even some heavy-duty automotive relays.
