boat manual

i recently bought 23' 1986 regal ambassador. I have contacted regal.com and they could not be of any help for me to get a manual. My air conditioning blows hot, need to know about freon. Can't figure out if the refrigerator works. Doesn't seem to work with the radio or microwave or air. Any help would be greatly appreciated.
