2000 Ford Mustang 3.8l
Replaced ac parts and when I was recharging my system , the low side gauge went to near RETARD and stopped taking Freon.
I then started checking my electrical components .

I have no power to my ac compressor .
No power to my high pressure switch.

I tested my b/w wire from the CCRM to battery negative and it reads OL.

I tested the ground of the high pressure switch and it reads -7.5v. (Test light connected to battery positive )

I don’t know where to go from here .
PLEASE HELP!

Compressor, condenser, liquid line hose, discharge hose.
I noticed that my compressor has no voltage to it, and my high pressure sensor doesn’t either .
I bypassed the low pressure sensor and nothing happens. (Low pressure sensor has voltage)

Was the AC working before the swap? I guess the question is why did you change the system.

I replaced it due to the compressor smoking .

Ok. So it had power before the swap. You don't have power at the harness?

Nope, there’s no power at the connector . When on I checked for ground and both wires had ground .
