My inital impression is there is a failure in the RA motor drive train. ___end___ Mon May 19 23:58:04 GMT 2014: PSPT Abort Patrol GENERAL OBSERVATORY COMMENT BY berkey: Tue May 20 02:17:21 GMT 2014 Seems like the issue is either with the clutch or how the clutch assembly enguages with the worm gear. Currently RA drive system is apart. I will come up tomorrow and hopefull with two peopel we can figure this one out. ___end___ KCOR COMMENT BY berkey: Tue May 20 02:19:56 GMT 2014 Kcor Nema box is powered off. During the RA trouble shooting I found the nema fans too loud, when I was trying to hear some of the noises the drive was making. ___end___
