"I had a great-running 1980 Peugeot 103 SP moped...that is until it stopped producing a spark. I tested the electrical system, and everything seems fine (the lights, horn, brake lights, tail all work) but there is no electricity getting from the magneto to the coil. I took the points out and cleaned and filed them, all to no avail. I inspected the wiring coming from the magneto and it looks fine. I have no idea how to take apart the magneto because the flywheel seems permanently fastened to the crankshaft. If anyone can give me any suggestions on how to get my ped running again, please reply!"
