Well Volks,

       Pay attention to those pressure readings and bypass switchs.  I just
lost all my freon due to a clogged drier.  Any tiny relief valve just went
kaplooey on the top of it.  Fortunately I had another drier and put it in.
Going over to the shop for a recharge.  If you haven't serviced your air in a
long while or the drier hasn't been replaced since the dawn of time....do it.
It's cheap insurance.  Some of the symptoms I had were RPM relative whining
from the compressor (starved for freon) and increased coolant temperatures
from the buildup of pressure in the condensor.  More to follow I'm sure....
but I guess the phrase for the day is "scrimping on parts is just dumb!"
