With the connecting and disconnecting the cables in  hunting and fixing ground loops at EY the side coil on the RO failed to drive the suspension.  Investigating it was obvious we had no coil connected. (Could not see 40 Ohms on the pins)  Check the feed through and everything appeared good and tight but it must have been seated oddly.  Reseated and tightened the connection and the coil was fine.  40 Ohms at he Sat amp 45 at the rack.

Fil and I also took this opportunity to replace the Binary IO card that had failed for the read back.  All signals seem to work now.
