Just came back from a week long ride at the West Virginia Hatfield and McCoy trails. The first day my ADC performed just fine going down some steep hills. After the ride I took my 2013 850 to a local spray wash to get the mud off. The next day the ADC did not work at all. The 4 wheel drive performed fine, just not the ADC. Obviously I got water in it somewhere, but not in the switch. Now back home the machine had some time to dry out, especially on the 650 mile trailer ride. The ADC now works. Anybody else have this problem, and if so what should I be looking into. Thanks Mike.
