    Isn't there a diagram on the motor or in the box? Two browns to cap. the other go to 120 hot. one for each leg. Do you have the right cap. for that motor?

        It is a good practice when you buy a motor to buy a cap. with the motor so you
        know you got the right one. Are you saying there is no diagram and it does not tell on the motor what cap it needs? Paul
