If you're running R134, calibrate your POA valve for that pressure (youtube) and maybe adjust your TXV if the superheat is not in a good zone. A parallel condensor will help but is not necessary

From what I understand these earlier compressors don't have a superheat/switch. Literally all there is is one power wire to the clutch, with its second wire going to ground, right?

The AC runs cold with the system configured when I bought it, and we just evacuated/refilled the system to insure we had the correct amount of R134a versus the factory-spec R12 fill.
