I have a 2008 Sportsman 500 Ho that starts well and runs great, but does not charge the battery. After idling for about 20 minutes the battery light begins flashing on the console. Voltage on the battery at idle is around 11 to 12v, when I rev engine, voltage does not increase. Battery drains the longer it runs. Rectifier/regulator seems ok. I swapped with one from my other Sportsman and same lack of charging. How do I test the stator and coil and what readings am I looking for on my multimeter? What other components should I be checking?

Thanks for any and all help.
