Hello community, it’s about a new china scooter ( 50 he) that doesn’t belong to me, but I need to get to work. Why, why and how play no role now. There’s no ignition spark. Parts have been changed. alternator (at first zero volts, now 55 volts at start) , cdi, spark plug, battery new, First picture: both cables come from the alternator. Deliver 55 volts now. Second picture: before the ignition coil should 12 volts concern , it comes 0 volts at . With the old Lichtmas chine 3 volts. Third picture: backup ok. Fourth picture: the green cable goes into the cdi, there would have to come out 12 volts yes, or ? Does not seem to be the case. Question: all parts would have to be plug and play, therefore I close a confusion. Why does not the ignition coil come to power? How do I check the ignition coil? I have, if I check the two poles with the multimeter beeps it. Is that ok? Or is this defective. Cables from the ignition coil are ok and checked. chts, if nothing comes before. What can I do?
