I have diagnosed that my field coil on the 2005 Optima has an open circuit. I still have the compressor on the car and have removed the clutch hub, pulley, and bad field coil. I cannot seem to get the new field coil on. It seems just a bit too small to fit. I know that I need to align the notch, but I still can't seem to get it on. Right now I have reinstalled the pulley and snap ring without the field coil and clutch (I broke the bolt on the clutch hub) just so i can drive it still. Please tell me the secret on getting this thing on.
