If you download the manual for you year model it will walk you through how to check all that, Its really simple. Also I'm not sure which gens were fully effected. But the Gen 3 have a warranty bulletin on the regulators, But when My stator went out my local kawi shop was able to get kawi to replace the stator with the regulator since it caused the stator to die. Mine died on me in a parking lot, I have a shorai battery and it didn't show any signs of getting weak, just died! But download the manual and get to checking!
