Checked the following cables for possible shorts. 


PRM TOP (Cable 10 air side) - Found short on Pin 13 to chamber ground. Andres inspected cabling and saw no obvious short. He removed aluminum foil cable tie on table and short disappeared. Could not reproduce short.

PRM RIGHT and SIDE (Cable 11 air side) - Did not find any short to chamber.

PRM Middle (Cable 31 air side) - Found short on Pin 13 to chamber ground. Traced in-vacuum cable to feedthru. Short appears when you move the cable going into the connector. Will need to repair or replace cable.

MC3 Middle  (Cable 25 air side) - Found short on Pin 13 to chamber ground. Andres inspected cabling and saw no obvious short. He removed aluminum foil cable tie on table and short disappeared. Could not reproduce short.
