The entire assembly. If any of these pictures need clarification, just ask (I didnt know how to put all the images in one post). Thank you all for your time. All the wiring on the engine comes from the generator, goes into that black box, then works its way across the bike to the lights, horn, condenser, etc. Hope these pictures help clarify things, or make you think of another good reason preventing me from enjoying this bike (at the moment). Im Canadian, and its Thanksgiving here, so have a nice Thanksgiving (or Columbus Day) if you're in the States. Also, if you think the pics are too out of focus (or you notice something of importance in the background) let me know, and Ill try to get a better shot of it.
