I just picked up a General 5-star with a Minarelli engine. I cant get a spark on the plug. I checked the points and they close and are clean. I am using a new plug. Can anyone tell me whether lights and things not working are related to not getting spark on this ped? Right now there is no battery on it. I imagine all the lights run off the battery? Any wiring diagrams anywhere for this moped? Any help is appreciated.
