Where can I find wirings diagrams for Hunter fans?

There isn't much to a fan's wiring. What do you need to know and is there a light kit or a remote? Another thing to tell us is what color wires are in the ceiling box and how is that switched, maybe at the wall.

What is the issue with your fan?

All Hunter parts and diagrams can be obtained if you call hunter. See Hunter Fan - Ceiling Fans, Air Purifiers, Humidifiers, Thermostats
