Default 2004 sportsman 600 no spark - scope log attached

Hey guys and gals. Long time lurker. First time poster.

04 sporty 600. Late production ignition system with separate coil and cdi.

chasing a no spark scenario.

Here's the fun part. I have 2 new stators, 2 new cdi boxes, and 2 new coils, and still no spark in any of the above combos.

Went thought the normal routine of chasing no spark and peak voltage. Kept getting weird numbers. So decided to start from scratch with an O scope.

testing both new stators I have, isolated from the quad with only ground straps. Signal from both across orange and white wires show pretty close to the same peak voltage waveforms, in ac. Far less than what the manual says for peak DCV of 3.3v.

when I plug in cdi with 12v battery power only, I have a few bolts peak coming out of the coil plug. Both cdis act the same with both stators.

need some help here. I can't say I've ever seen a bad flywheel. But to have two brand new stators show the same low voltage signal is odd. What am I missing?
