How does the two "module" ignition work?? I've always thought it was a primary (larger) coil mounted @ flywheel and a secondary ( high voltage)  mounted under the top cover???

Exactly, the large piece creates initial voltage then sends to secondary which steps it up again to create spark.

Thanks Tim.  On the heated handle variants does the primary Coil provide current or is there a separate  coil pack UNDER the flywheel?   Trying to figure out the reason why husky used two coils!!! Adam

You are correct a separate coil pack but also a different flywheel part number. I do not know if there is any real difference in the two flywheels except that the one used for the 'G' models may have different machining on the rear to make room for the generator. There are other 'G' model saws that do not use a two element coil like the 262XPG so do not think that the existence of the generator dictates a two element coil. IIRC sometime in the past I used the 'G' model flywheel on a non 'G' saw and everything was fine. 

Would be interesting to know how much voltage the generator puts out. I dig around and see if I can find out. My guess would be between 6&14 volts.

The generator puts out 65 watts at 10K RPM. Given that Volts times amps equal watts, my bet is that the generator puts out 12 volts and 5-6 amps, just a guess given the gauge of the wiring. Cannot currently find a spec on the voltage used. Troll likes this model of saw so perhaps he will come along and tell us.

Jeff, any luck with the last test? Don't forget send an address by PM and I will send you the correct wire, no charge.

I tried everything but the volt meter. Its AWOL. No dice on spark. This things starting to make me feel stupid.

Don't feel bad, it happens! There is something that not only you are missing but the rest of us to! Did you try making sure there were on grounding situations with the red wire? It is possible that the new unit you got is defective. I looked around and I do not have a 288  coil setup on hand that I could send you just to try.

This is REALLY a stupid question (so do not take offense) but earlier you said you were turning the saw over with a drill motor. Which direction do you have the drill motor set to turn clockwise or anticlockwise? IDK for sure but logic tells me the ignition system will not make current if turned in the wrong direction, otherwise you run the risk of the saw trying to run backwards. You should have your drill motor set to turn the flywheel anticlockwise.

If there are no ground shorts and you are turning in the correct direction and no spark I can only suggest that one piece of the new coil setup is defective!

Bad flywheel? Just had that issue on a 3120
