Abstract
Problems with the mount encoder position values and the RA drive were investigated and found to be caused by corrosion around the encoder header connectors on the PCB, and general dirt brought in by the cooling fan. The mount controller and RA motor were replaced with spares from Birmingham, resolving all faults. The delta-B module was decommissioned.
