Following our weekend gun high voltage repair and testing, today we removed the J6 jumper which permitted the HVPS to enable with the gun vacuum valve closed. I removed the corresponding ABIL entry as well.

We are again in a normal gun HVPS interlock configuration. For example, with the gun valve closed we no longer hve a Global Vac/Valve permissive.
