Hi José, the measurements to know if the motor is in good condition or not, are quite simple, you just need to have a multimeter and place it preferably on the diode reading scale, then you must proceed to measure one by one, each of the motor cables, all among all, for example you must choose any color and the rest of the cables must have or mark a resistance reading with the other cable colors, and so on, I repeat all against all, yes one of the measures do not work out, because the multimeter does not mark anything, in that case the motor would be damaged in your winding and you would have to send it to rewind with a specialist. if all the cables have continuity with each other, in that case I should assess the comments of my colleagues, about the condition of the bearings or of the capacitor itself, if the equipment was already recently intervened by a technician, it may have varied the connection of the cables, so if in doubt you can keep asking and I explain how to know the connection of each cable, which for a better explanation, I would need to provide the colors of cables, their values among all and if you have the electrical diagram of the equipment and the engine itself does have it outside its housing.
