Hello everyone,

I could really use some help trying to figure out a problem Im having with my 2015 Sportsman touring 1000.
It won't start. it turns but that's it. I figured it was the spark plug so I took them out and tried quickly to turn the motor to see If im getting a spark but no spark to either one.
Next i checked the ignition coil. I saw a video online from RMstator showing that I should be getting about 1ohm resistance on the primary and 10k resistance on the secondary. The primary measured right but the secondary shows open/infinite. So I went ahead and ordered a replacement from RM Stator. Received the replacement a couple of days later and measured the secondary only to find the new ignition coil shows open as well. Figuring it was defective, I ordered another one and once again the secondary doesn't read anything resistance wise. I was starting to think that this type of coil doesn't have any readings on the secondary and it must be another issue. I connected it to the bike anyways just to see if it would start but nothing.

things Ive checked:
-spark plug wire breaks---> I checked continuity and resistance and they both check out fine.
-fuse box---> all fuses seem good.
-spark plugs---> checked resistance on both and one reads 4800ohms the other 5500ohms. No shorts or breaks
-brand new stator was installed last month by motocross/atv mechanic. It took them 4 months to get all the pieces in because of covid related B/O. When I finally got it back, I went on a 3hr long ride with no issues. Next ride a couple of days later, it wouldn't start.

SO, this brings me to my question. Does anyone know how I can troubleshoot this issue? or what should be my next steps? I really don't want to bring it back to the mechanic and lose it for many more months unless Im sure its has something to do with the stator they replaced.

Thanks

If you are testing correctly...................

Refer to the schematic below
154929

You test the primary of one coil RD/BU to BK and the other coil RD//BU to WH - test the secondary plug wire to plug wire or plug wire to ground or plug wire to RD/BU
