I was out blowing snow today with my S185 and after about 2 hours of being out I stoped to answer the phone and when i started to go again the boom would not go up or down. When I pushed the green button for the inter lock control system none of the lights would light up. I was able to drive it back home and I had to hit the red nob to lower the blower so I could get out of the cab. I went back out 2 hours later and started it again the inter lock control system still did not work. I am seeing if there is some easy fix before I call the dealer. Thanks for any help, Andrew
