It may be that that there is another problem with the limit switches for the geneva drive that is causing it to stop at only one position instead of four (QWP). **ECHO PROBLEM**: Thu Jan 4 21:29:20 GMT 2001 The motor isn't turning the geneva drive for the QWP. There is 13.0 vdc across the motor input when it should be turning. The motor makes noise but no shafts can be seen turning. The QWP is stuck close to one of the 4 positions it turns to. **ECHO PROBLEM**: Thu Jan 4 22:00:30 GMT 2001 The motor shaft is sheared close to the motor at the E-clip groove. The geneva drive must have too much friction for the motor system, it was hard to turn the free geneva driver mechanism without the motor or it engaging the geneva driven mechanism. Kim says to remove the entire motor and QWP mechanism and send it back to them in Boulder, they'll order and install a new motor and check for the cause of the geneva friction and check the alignment of the QWP. Will remove and ship today. ECHO is down until we receive the repaired mechanism from them, maybe 2 weeks. I will do a "Partial Shutdown" as defined in our documentation, the heat exchanger will remain on but most everything else including the computer will be turned on.

Will stop by Fedex office and send today in Hilo.
