Marshin/Lifan 200cc ATV No Spark

[bmd1198]

I've been trying to diagnose this old Marshin ATV for a while now for one of my customers (I primarily work on cars, but I mess with small engines too) and I cannot figure out why it's not getting power from the stator. It's a Lifan 163FML motor.
I had to redo the wiring on it since the original harness was all melted. I replaced the harness with a kit from Amazon, and now it cranks (had no power before) but it doesn't start. There is no spark. I traced that back to the stator, which is not producing more than a couple volts. I did all the usual tests, and I am now on the third stator, so I know the stator itself isn't the problem here (then again, parts quality is lackluster nowadays). Everything appears to be wired correctly based on various diagrams I've found online.
If I remember correctly, I was seeing maybe 5v AC from the stator on the power wires. There is also no spark signal at the pickup, therefore the CDI is getting absolutely nothing. Everything is grounded well, so it seems to be an issue with the magneto/flywheel from what I can tell.


Is there something I'm missing here? It's been a LONG time since I've messed with ATV/powersports motors, and back when I had more of them, I wasn't as mechanically inclined (I was maybe 14 at the time lol). My small engine experience is mostly with lawnmowers and outdoor power equipment, so I'm hoping there's someone with more experience who can point me in the right direction.


I'll attach a few photos of what I'm working with. The first pic is the connection between the stator and harness. I know it's messy, but it gets the job done.
