We're bumping the spar around a bit as we check out the mk4 problem.
**MKIV PROBLEM**: Sat Nov  9 21:29:47 GMT 2002
Tracing the problem back from the Transceiver board to the Tiltout limit switch
it looks like the limit switch is shorting, there is continuity between all
3 terminals when the switch isn't activated.  The switch was changed last 
week when the problem first appeared.  Still checking the wiring near the
switch now.  I had to remove the small section of the telescope that the
terminal strip before the limit switch is connected to, to get to the 
terminal strip and switch more easily.  I'm not sure if I did this years ago
too but it seems kind of familiar.
**MKIV PROBLEM**: Sat Nov  9 21:41:17 GMT 2002
When removing that small section of telescope tube I noticed that is was burnt
in places from the solar image because it is near the focus, probably happened
during telescope offpointing.  Allen just came down to let me know that he
found a burnt area on the existing small cable that runs from the terminal
strip to the limit switch, maybe the solar image burnt that enough to cause
the insulation to melt in the cable and shorted the wires together.  The
solder joints all look good so a shorted cable makes sense.  The wires in the
cable are very small gauge so I found some bigger replacement cable and Allen
will install a longer section of that.  In the future it'll be easier to solder 
to that wire gauge and there will be a longer cable run so nothing will
stick out into the edge of the light path like the old cable did (slightly).
