Katy-West Houston Air had written this in response to
http://www.thestuccocompany.com/hvac/Re-Condenser-Fan-Motor-1309-.htm :
The RUN and START windings are reversed on the run capacitor. The run
capacitor has 2 wires comming from the motor, and there is a power wire
also attached to the capacitor. Leave the power wire connected to the
capacitor and reverse the other 2 wires....the motor will now run in the
right direction.
