Looking for tips on troubleshooting a magneto with a no spark condition, tried replacing the ignition coil and still no spark, so I would like to verify if the induction coil is at fault. I think the output is AC but not sure what is the  correct magnitude for this output

I don't have a schematic, I'm helping a friend with his Husqvana chain saw so I don't have access to the chain saw to take pictures but there are parts diagram on the web and it appears the ignition system consist of an ignition coil, ignition module and a "generator" a toroidal shape coil of wire located coaxially -inside the "flywheel". I'll have an opportunity to take this chain saw apart next week. I'm not sure how these three components work together to produce a spark-couldn't find any specs on the web.
Thanks for offering to help

magneto = magnets spinning on flywheel, induces spark into coil. magnets are placed on the flywheel according to timing of the engine. gap between flywheel and pickup or 'magneto' should be about the thickness of a credit card. also, the magneto usually has a black wire that will ground the ignition (shut it off) in case of safety or user selected shutdown. check this wire first and the switches that go to it, magneto failure is rare on any small engine. common failure is switches on the shutdown circuit, wrong gap, or rusty magnets.....

The CDI maybe at fault, the operate differently then Intuction Igntions (auto ignitions) do.

CDI has a capacitor that is charged by the magneto charging coil (one of  the 6 or more coils on the magneto) and the capacitor, once charge is released by a SCR switch inside the CDI Module thats triggered of the fly wheel.

Which is why no battery is required.

If Voltage is coming into the CDI Module (via the charging coil) but not coming out of the CDI, check the the triggering device signal at the CDI, (low voltage a/c signal sent to CDI) if thats present, and still no output to the coil (coil steps up the Voltage to an even higher voltage) then the CDI Module is at fault.
