If it is on a Copeland compressor Copeland makes an electrical handbook for all of their motors and units. You can get one at most supply houses. I highly suggest it. I can't count how many times its been midnight on a Friday or Saturday and I go to the book and find out what relay or capacitor I need.
Tecumseh also has their compressor electrical info available online here: http://boxload.tecumseh.com/ESPGuide.aspx
(This one is still in a basic format, but will be added to their website sometime in the near future. Thanks to Andy Schoen for providing us with a link to it. )
