Hi Liebe Schrauber has the following problem with the scooter and that is that I have neither an ignition spark nor get the cylinder fuel the fuel pump runs also not except one breaks this. I checked all fuses and also the relay switches the relay for the ECU (1 relay of 4 total) the remaining relays do not clack and get on the control side no mass therefore I guess something with the control unit is not in order. I got the ignition cable including ignition coil gemes 2k ohm . The scooter stood out over the winter and renewed the battery. Maybe someone still has an idea because the ECU costs around 300€. Look forward to any helpful reply greeting Schotti.
