Hey Everyone,
My dual magnetos are close to the 500 hour mark so I’m looking at changing my ignition system. My plane already has dual alternator and dual battery, so I’m considering going with dual electronic ignition. The plane has 4 switches which connect/activate the alternators and batteries to the main bus. FWIW, the plane is using an ACM from advanced and the EFIS has a backup battery as well.
For the purpose of this thread, lets IGNORE debate on:
1. Which ignition system is best
2. Why not just use a P-mags (which I am considering)
My main question is assuming I do dual electronic ignition that does NOT have its own power source, what is the best way to wire them into my plane? I’ve seen some cool setups that split the plane’s power into two halves with one ignition on each half which seems optimal, but this would require more switches, more solenoids, 3 more wires to the batteries in the back of the plane, another volt meter, and more complexity.
Is there an easier way that is also robust? How about a battery isolator or some combination of diodes to the second battery to allow it to charge off the main bus but not go down if the main bus shorts?
