I bought a 2015 84 inch angle broom a week ago to do snow removal of my rental properties. Upon receiving it, I hooked it up to my 2008 S220. I was able to spin the broom but not change the angle when I push the left / right arrows on my right joy stick. I really have to even think about bring it in to the Bobcat unless I know that's not what I can trouble shoot and fix. Actually the skid just came back from them yesterday after $1200 repair work. How can I test if the S220 is sending out the proper signal to the connector. I'm pretty proficient on electronics if I know the pin out and how to test them. So far I can only tell that there is a 12V switched power to the top larger pin and a 12V unswitched power to the other larger pin. No meaningful measurement on the 4 smaller (CAN, signal) pins. Help greatly appreciated. Thx. Erwin
