I'm going through issues with my '01 sportsman now. You should get an ohm reading when checking at the connector going to the coil. Power to the connector is only on when the key is on, awd is on and the gear selector in in drive.
In my case the right frt hub was dry, so I filled it with hub oil. The resultant goo was to slick to allow the Hilliard clutch to operate properly. Found out my coil has magnetism, just need to install new seals, clean everything up and put it back together.
