I am soon going to have an 0-320 overhauled and am considering at least one and maybe two electronic ignitions. I attended two forums at Oshkosh and basically heard the same speil from two different companies.
Standard magneto's require starting then they are stand-alone systems. That seems to be their claim to glory as they will keep running even with an electric failure. Their downside is there is no spark advance as rpm's increase.
Electronic spark systems work exactly the same way except they have spark advance. The preflight check requires each ignition to be isolated then momentarily disconnected from battery power. If it keeps running all is well. Works off the standard "right-left-both-start" switch plus a momentary "disconnect switch" for each unit.
Please educate me on anything I obviously don't know or am misunderstanding.
Thank you,
