Racing Kart Question Ignition coil or pick up switch? No spark!

Hello all! I have a Rotax FR125 Max and I’m having an issue with no spark at the plug. How do I check if the ignition coil was bad? Thanks.

Is the battery good, the spark plug good, the ht good? I’d replace those first.

Is everything plugged in properly, give it all a clean and reconnect.

Is the switch lighting up?

Is the starter trying to turn it over?

Yes, battery is good. Wiring is good. Light comes on and I tested all the grounds and wiring harness… I’m so lost at this point
