Help! How high should the tension of the Lima be?

The problem, my runner has no spark, ignition cable, candle and spark plugs are already new. The funny thing: He ran about 2 weeks ago still… off, no more sparks.. Was already at the measurement… On the green cable which comes from the LIMA, however, there are only 3 V, in other videos people achieve up to 90 V On white and red there is no tension, on the circuit diagram have exposed the ignition, contacts rusty t… sanded off, now clean again, but no sparks Thanks for the help… Scoot: Gilera Runner C14 50 LC BJ00 25.000KM radiogo7
