Team,
Working on my 84' AC system. I filled the system with (AC Pro purchased at Orileys) 134A. Once the guage was in the green (see pics) the compressor cycles on and off very quickly when the Low pressure switch is wired up (see pics). When I bypass the switch (see pics) the compressor stays engaged.
The low pressure switch is brand new (see pic). I know very little about AC systems, and I'm obviously missing something here.
Any help would be appreciated.
Thanks in advance.
