I finished pulling a vacuum early this evening and began charging. The good news is that it holds a charge great, however my a/c clutch would not engage. Static pressure on the low side went up to 100 PSI and held but without the clutch cycling I stopped charging in fear of overcharging and blowing something out. I checked the connections on the high pressure switch, low pressure switch, and compressor clutch and everything was good. So I just left the system sealed and stopped so I could cook dinner and so on.
At this point the problem is likely electrical and not mechanical. Luckily my first step in troubleshooting revealed at least one culprit. At some point the fuse to my cycle switch (low pressure switch) blew. Unfortunately I didn't get a chance to check it until around midnight. I'm going to pick up some fuses in the morning and with any luck this will be the beginning of the end. At this point there aren't many more pieces in the a/c system that could cause a problem.
