So what would be the top three things that I should check first? Yes the lanyard for the kill switch is connected...

first I would open the manual and break out my Cd-77 peak reading meter.
then I would remove the white wire from the CDI and retest spark, then I would test stator output,trigger output then CDI output, then I would replace the defective part cause by now its isolated.
