Electronic – Run electric motor CW & CCW with DP-DT switch

electricinduction motor

enter image description hereI have a Harbor Freight drill press 1-1/2 hp, running on 120 volt, capacitor start.

Is it possible to run CW & CCW rotation, using a DP-DT switch?

Motor has four wires coming out of it, all with color and numbers.
black #1/gray #2/red #3/yellow #4

The picture is from the motor, if this is possible please show the wiring diagram. Thanks.

As the motor is capacitor start, the answer may be yes, if the four wires give you access to the main and start windings.

Try starting the motor with the start winding reversed, it may start in the opposite direction. The main winding stays connected as normal.

As the circuit diagram tool isn't saving for me at the moment, let's see if ASCIIart will do.

To identify if you do have all the wires for all the windings, measure the resistances between the wires with a meter. You are looking for two isolated windings. The main one will be lower resistance.
