Getting to know my first skid steer… Bobcat 763 C series - Recently, I started the machine, pressed the lock release and raised the bucket a foot or so. Before could move forward however, the interlock re-engaged. Right now the hydraulics/controls will not operate. After reading online, I thought I was looking at either the seat bar sensor or the sensor underneath the seat. But then I noticed the BICS module for the very first time and it is completely dark (no lights at all). Not certain but I'm assuming it was once previously operating. So, it appears that I need to get the BICS operational but really not sure where to start. Anyone have some troubleshooting steps for this? Also, is there a way to isolate the various sensors one by one to determine if they are working? Thanks!
