2007 Sportsman 90 No Spark/Stator Question

Hi all I have a 2007 Sportsman 4 stroke 90.

I was wondering what the test spec/procedure is for the 4 wire stator?

Also will shorted out starter damage anything else in the system?

I know the regulator/rectifier is bad as well, I am assuming this was caused by the shorted battery.

Trying to get it up and back running, currently has no spark but before I spend any money I want to make sure the stator is good, to prevent further damage.
