Thanks, Mak. There are three unmarked terminals on the compressor. One is undoubtedly common since it has the thermal protector in series with it. If I touch the other two terminals in order to find out which will run the compressor, am I going to damage it if I touch the wrong one first? One shows 1.2 ohms to the common lead and the other shows 2.1
I don't think I have room for two capacitors in the A/C since the dual cap and the control pc boards take up most of the room in their compartment.
