Problem(s) Encountered:

I got a fault when I tried to move to the first target - the telescope was not moving in dec so it shut off the tracking and refused to proceed.

Solutions:

On Eric''s suggestion I cycled the dec drive power, but it made no difference.  We brought the system down and cycled power to the big control box in the computer room, but even then the dec refused to home.  

By coincidence, Dick Treffers is on the mountain, so I emailed him in hopes of catching him before he went to bed.  He got the email and scooted down to take a look.  After a couple of hours he''d fixed it -- a connector had gone bad on the bottom of the big control box in the computer room, so the dec motor driver was not getting the signal to move, even though the signal was appearing at the source.  He removed the connector and wired the relevant wires right onto the terminals in the control box. This will have to be cleaned up later, but for now, it works fine.
