Recently the capacitor went out on my Ducane unit. I ordered a new one. Well I didn't do the first rule of electrical wiring, "Take a picture" or "Write it down". I do not know how to wire in the new capacitor. The original diagram from inside the unit is no longer there. I have a dual capacitor and the unit has the following four wires to hook up to it: white, brown, orange and purple. I have looked as much as I can and I am not able to locate any diagrams or manuals that have the corresponding colors. I know for a fact the white goes to COM. It's just the other three I am not sure about.
