Well, I've done that and it still does not draw refrigerant into the system. I jumped the pressure switch to get the compressor to turn on and the clutch spins freely while it's on. It's not intermittent.
I really need to know how to get that pressure gradient taken care of. Do I need to evacuate the system and draw a vacuum again now that I have the compressor running?
