how to fix a raptor 660 pickup coil problem?

Question

the pickup coil goes out, theres no spark but the stator is fine

Answer 1

Buy a shop manual for electrical specs and troubleshooting the ignition system. You spent all that money to purchase your raptor and you want to do your own repairs. I don't think $50 is a lot of money and it's a worthwhile investment.

How do you know that the stator is putting out voltage to the coil?
How do you know that the ignition coil is OK?
Did you check them?
The pickup coil is just like a set of points and tells the ignition coil when to fire.
