Hello friends, I have a problem with my Jetti. I made the service new (all liquids and new spark plugs. Roller also ran great until then. Unfortunately, the spark plug was not on properly and flew off when I wanted to go. Unfortunately I did not notice that the plug was off and I therefore continued to try to start the scooter. The next day I noticed that the plug was off. Error memory were 3 errors,2 of which I could delete. The scooter starts at 3000 turns and turns up to 4500 high, that’s it. It doesn’t move from the spot. I measured the spark plug plug and the ignition coil(had changed a second crosswise) but without success. Alternator charges the battery at a measured voltage 14.2Volt in charging mode. Lamp also goes out immediately after start. I hope not that I have a short circuit v If someone can help me or knows the problem then I would be very grateful. What do I have to measure in this case and above all how? I am a good screwdriver but of electronics unfortunately I don’t have the idea. It is as described above a Peugeot Jetforce 125ccm ABS BJ 2007 without compressor. Would be a pity if the scooter can no longer be saved, there are unfortunately only limited spare parts. I thank in advance and h open to good expertise. Greetings Ray
