It is a three inch fan and i want it to rotate to other direction .I've tried cutting the wire and reconnecting them inverse like black to white and white to black ,but it won't start rotating when i plug it in that way.And then it works again when i rejoin the wire to the way it is. I don't know what causing the problem.Is there anyone familiar with these small mortor?Any suggestion would be appreciated.Thanks!! http://i296.photobucket.com/albums/mm163/sasukebloodwheel/110527-105859.jpg
