Its not going to turn on with no freon/pressure in it, it has a low pressure sensor that keeps it from turning on and damaging it. Need to cut the wires and run one to hot one to ground, if you here a loud click, the clutch engaged and it will run. Start it press the wires to the battery and see which is your output.
