Hi. I am stuck troubleshooting a no-spark foult on my motor. Motor died suddenly, it wated to fire up and actually caught for about 1 second then died. I quickly found it had no spark to any of the 3 cylinders. It's got electronic ignition. Anyhow, I am following this checklist: (page 9 of the pdf, or page 23 in the doc).

I got to step 2 (big progress)... but it took a while to get that far. I couldn't determine how to disconnect the black/yellow wire to check the kill switch. Anyhow, I ended up just cutting it near the power pack. There is still no spark, and this is where I am stuck. I found 2 yellow wires connected together on a vertical gang strip, and I removed them from there and separated them, still no spark. But I'm not sure this is what I'm supposed to do... perhaps I need to remove the rectifier and disconnect the yellows from in behind? Any help appreciated.
Also, step 3... where do I test for resistance? I found a few connectors with brown wire anda few with brown/yellow... but no connector that I can see has both together. I got zero connection/resistance to any of the ones I checked. Looking at the pictures of stators I believe I may have to remove the power pack to get at a connection stuck in behind it... any help appreciated.
Do tests 4,5,6,&7 have to be done with engine turning over or ignition switch on? (I assume the former).
If there is a pictorial or descriptive article to help me do the other tests I'd be most grateful for a link. I have a peak reading DVM on standby.
Thanks, Duke.
