Here is a visual Wiring Diagram reference for common configurations. You might want to confirm the connections with a meter before applying power. For low voltage the motor coils are wired in parallel, for high voltage they are in series.

Also, Ugly's Electrical Reference is a handy reference for such things.

I agree with Wash and Stan. I have seen too much poor DIY work end up cost more in the end not to mention unsafe.
But on other hand if you are interested in how it works, The windings are wired in series for the 480v and wired in parellel for the 240v. Putting 240v across each winding(Basic Ohms Law)
