There is a round thing in the Common wire on the compressor connections. The compressor won't run. I am trying to find a way to jump the compressor to make it run and rule out a bad compressor. If I jump the capacitor, will it make the compressor run? Also I installed a service port for the low side and static pressure shows 120 psi or more. On a car, we used to jump the low pressure sensor with a paper clip and force the compressor to run but I can't do that here. Thank you for your reply!
