Riding home the other night my bike started overcharging the higher the rpm the more it would overcharge i was able to see the battery off of my power vision im sure the voltage regulator is toast but can I test the stator to see if its bad to before I replace both?

 

Might try this-

If its overcharging, its just the regulator that needs replacing.
