Couldn't find anything wrong so I cycled main KCC power and the barrel unwound CW and stopped properly at normal startup position. Started Patrol and the barrel rotated around to 274 and CCW limit again and stalled. No analog signal visible either. ___end___ Tue May 25 19:25:06 GMT 2010 CHIP End Patrol **MKIV PROBLEM COMMENT BY DARRYL**: Tue May 25 19:25:26 GMT 2010 No 15v output from power supply at back of spar. Spar is unbalanced so I stopped instruments while I check out power supply which I removed from spar. ___end___ **PSPT PROBLEM COMMENT BY DARRYL**: Tue May 25 19:36:04 GMT 2010 Crashed, restarted. ___end___ Tue May 25 21:25:35 GMT 2010 CHIP Start Patrol **MKIV PROBLEM COMMENT BY DARRYL**: Tue May 25 21:25:41 GMT 2010 Confirmed that +/-15vdc power supply for camera is dead, reinstalled it in spar to rebalance the spar, then restarted other instruments. I'm having trouble finding new power supplies but I have a good lead to a new surplus power supply that I'll calll early tomorrow. This is old and obsolete and hard to find, such are many things for mk4. ___end___ Tue May 25 21:30:20 GMT 2010 MKIV End Patrol **MKIV PROBLEM COMMENT BY DARRYL**: Tue May 25 21:32:01 GMT 2010 Mk4 is down until we replace the +/-15vdc camera power supply. ___end___ Tue May 25 23:01:41 GMT 2010 CHIP LSD Tue May 25 23:03:10 GMT 2010 CHIP End LSD Tue May 25 23:03:19 GMT 2010 CHIP BiasLSD Tue May 25 23:03:55 GMT 2010 CHIP End BiasLSD Tue May 25 23:04:03 GMT 2010 CHIP Bias Tue May 25 23:04:36 GMT 2010 CHIP End Bias Tue May 25 23:04:44 GMT 2010 CHIP ReStart Patrol Tue May 25 23:35:22 GMT 2010 CHIP End Patrol Tue May 25 23:46:11 GMT 2010 MkIV 17_00.rawmk4 17_03.rawmk4
