Is The Low Voltage Opening and Closing The Contactor and is The Low Voltage D.C. Which Opens and Closes The Contactor This Low Voltage Might Be From The inside The House From The Thermostat Which Controls The Contactor …In Some Systems The Thermostat Runs On a 12Volt D.C. Which Opens and Closes The Contactor
The thermostat does not control the contractor. The board on your heater/ air handler does. The board sends the signal to the condensor not the thermostat.

No. The thermostat goes to board on the heater/air handler which then send the signal to the heat pump/condensor. The thermostat reads temperature it is not a control board.
Great explanation and execution. Good call on changing up the run cap to accommodate both fan and compressor

How do you know what size capacitor you need if the old one in unreadable?
I'll make a video of it
