    Depends on the type of motor.

    I am assuming you are talking about a single phase motor, over 1 HP?

    You have to reverse the "start" winding connections. Usually there are instructions printed somewhere on the motor or connection box.

    Look at the motor connections for numbers and look at the name plate, it may say something like, "to reverse rotation, reverse wires 5 & 8", or something like that.

    Thanks, Harold.

    It reminds me of an old joke/insult calling someone a "two wire electrician:"

    Two wires- hook it up.
    Three wires- f**k it up.
    Four wires- give it up!
