0Jack A Lopez 6 years ago The usual way to do this is to follow the wiring diagram that came with your new fan. Check the box that it came in, and see if you can find some of the documents that shipped with it. Sometimes the documentation will be incomplete, or cryptic. For example, it will give the wires funny names, or labels, like W1, W2, C, N, G, blah, blah, blah, without mentioning what these labels mean. In the event you cannot find a meaningful wiring diagram, try to come up with some words which describe your fan, like the manufacturer, a model number, the cryptic wire names, if you can find any. Then feed these words, plus maybe the additional word "wiring", unto Google(r) Images. http://www.google.com/imghp?hl=enThen see if any of the pictures it gives you, if any of these pictures resemble what you expect the wiring for your to look like.You can also share these clues, i.e. manufacturer, model, wire labels, pictures of the motor itself, with the human problem-solvers, here on the Instructables(r) forums, if you think this additional info might help us to answer your question.Although some of the peeps here are clairvoyant, so they already know your answer, like even before you ask the question.
