Rusty,
Thank you for this detailed and helpful reply. I did check and the wipers appears to be working well, and when started previously the headlamp goes on flashing with the strobe, the diesel sounds work, and later there are engineer announcements. The DCS switch appears set correctly. I am going to hold a little bit on taking off the shell until I can check a few more things. Currently, it is not responding at all, hoping it will reset and check a few more things out.
Mike
