Hello First you have to see the mechanical part of the centrifuge, take out the rotor and the taba of the motor where the centrifuge goes. You have to make sure that the centrifuge is squeezing the platelet contacts and when you contract it with the hand it disconnects it and let it a prudent separation, and when released connect the plate again. After that goes the electrical connection, one of the tips of the starter winding goes with one of the tips of the work and then you see the line. The other tip of the starter winding goes to the centrifuge plate and from there to the starter capacitor, and from there to the other end of the work winding with the other line.
