In order to reverse the direction of rotation of a capacitor start motor while it is running

Disconnect motor from supply and immediately reconnect it to supply with reversed connections of the main winding
Disconnect motor from the supply till it stops then reconnect it to supply with reversed connection of main or auxiliary winding
Reverse the direction of connection of the auxiliary winding and after motor comes to rest then connect auxiliary winding to the supply
Reverse the direction of connections of the auxiliary winding and immediately connect it to supply

Correct answer: 2. Disconnect motor from the supply till it stops then reconnect it to supply with reversed connection of main or auxiliary winding”
