AWD issues with the 2005 Polaris Sportsman 500. AWD is not engaging. Switch is on and the indicator light on the cluster is on. Switch is off and the indicator light goes off. Ran some electrical tests: Checked the gearcase coil resistance @ 24ohms (good); Checked the battery voltage at the hub coil wire at around 12V +/-; Continuity in all the related wire checked out. Before I take the front gearcase apart to check for internal issues, am I missing something? Anyone have any ideas or solutions?
