I own a 1983 Heritage Special. Runs better than good... My 2nd 650. (I owned a 1978 brand new) The Heritage has 2 owners prior to me. It has newer a charging system. Since I want to "clean it up" by removing ALL unnecessary wiring/parts etc... My questions would be: Is there a diagram available, OTHER than the tech drawings to perform this task? A diagram developed for the "layman" so to speak? I feel a complete re-wiring would be the best course of action.
