Hello dear thanks for the time and the good vibes, excellent the diagram is understood perfect. The doubt I have is that once you see each coil any of the two cables can be face or neutral?
Once the cables are identified, connect 1 of each of the coils and that is the common cable connected to the Neutral of the plug. From the union of the other cable of the Working coil with the capacitor the connection to the speed regulator leaves and from there to Phase of the plug.
