You can find a wiring diagram for a part-winding start AC motor in the motor's technical documentation or user manual, which is often available from the manufacturer’s website. Additionally, electrical engineering resources, online forums, and websites like Electrical Engineering Stack Exchange or specialized motor repair sites may have relevant diagrams. If you have the motor model number, searching for that along with "wiring diagram" can yield helpful results.
A single phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.
a start winding on a motor is used to add torque to start a motor, and more importantly to establish the direction that the motor will turn. to reverse a motor normally means to reverse the start winding. the run winding will work the same in either direction, the start winding determines the direction.
The run winding of a single phase capacitor start motor has a lower resistance than the start winding.
The run winding is typically rated to handle higher current than the start winding in an electric motor. The run winding is designed to sustain continuous operation once the motor is running, while the start winding provides the initial torque required to start the motor.
A split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.

If it is a three phase motor just interchange any two of the three wires. If it is a single phase motor, which is also known as a split phase induction motor, it has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.

No guarantees but try this connection. The white (neutral) from the power supply is common to both start and run windings. The black "hot" wire connects to a common side of the start switch. This means that the "hot" wire can supply voltage to both sets of contacts on the start switch. The switch's contact should be in the normally closed position. A wire should come out of the normally closed contact and be connected to one side of the capacitor. From the other side of the capacitor a red wire should connect to the start winding. The other lead coming off of the start switch goes to a black wire that connects to the run winding. This should be in the normally open position when the motor is not running. The start switch is a centrifugal switch that changes contact positioning after the motor starts to revolve. This in effect opens the start winding and closes the run winding.
It is called a centrifugal switch. The switch is in series with the start winding. When the RPM of the motor reaches a certain speed the switch drops the start winding of the motor out of the circuit.
