Now that we have finished with install and balancing of the ISI, I tried to do some basic check out of the ISI and found some cabling issues. The corner 2 actuators were crossed up, because the feedthru is labeled H2 and V2 on the ports, but the cables say coarse and fine. That was easy enough to fix. Corner 3 however, I can't get any drive on the H3 actuator. I checked the chassis is not overtemped and checked connections at the back of the chassis and at the feedthru. Connection is good, plugs are fully seated and the plug in the chamber is inserted right way up. The only thing I can think at this point is that I broke the wire in vacuum when I did the CPS swap. This will be annoying to fix I'm not sure what we have for spares either.

This will keep me from doing measurements of the ISI for CRS install and we definitely can't close this chamber until I can go into the nozzle between HAM3 and BSC2 to open the ISI up and look at the cable.
