So I pressed the trigger without the can screwed in and noticed a puff of air/gas and the needle reset to 0. I tried it again and the needle again jumped to 100. So do I have a bad gauge?


That is normal operation. There is a one-way valve in there somewhere to make it that way, it confused me the same way when i started my version of your process. To add more confusion; since my compressor wouldn't run, my 'low side' ended up at 90PSI even though it was really 40 maybe.



Everything i read from your posts indicates compressor not running to me. When i was 'at your stage' My next step was to hotwire the compressor to make sure the clutch engages, but i by insane luck happened to knock off the sensor wire connector that was causing the system to not run.
