I am restoring a 78 pa 50 that basically was missing all the stuff on the bars and thenfrontnsuch as ignition switch , headlights, kill switch etc. I have two nwiringnharnessesnand am getting things hooked up. As i stated in a previous post I bought some express switches and cables. So my immediate question is the red wire that comes out of the magneto. On the wiring diagram it goes into some kind of ignition switch which on the boxes on the top of the diagram is labelled bat. I also understand some pa 50 s had and some didn't have a battery. If I have a red from the magneto is it necessary to wire one in? Could I get some detailed instructions of what if anything to do with the red wire that I have attached to the red wire in the harness that goes by the tank to the front.
