I have a 1974 Vespa Piaggio CIAO. I still can't get a spark. I need some help on finding out what wires attatch to where. I have a plug attatching to a ht lead coming off the ht coil. From the ht outer coil there are 2 wires? Where do these wires attatch? What attatches to my condensor? I need an explanations of what wires are needed to connect to what and what the points and condensor do and what they connect to, etc.
