ALS Fiber glitches

With ALS glitching rearing its ugly head again We went through and tightened all of the connections and re dressed some of the fibers that would be vulnerable.  Tightening connections at the phase box changed the phase EX from 21 to 46 degrees.  Adjustment at all of the field connections glitched the system but EX settled back to 21 degrees EY went from 1 to 3 degrees.  Jenne then adjusted the phase down to 16.   Squeezing also saw a change from our work though we did ot change anything on that path.
