Turn signal, E-starter, horn and brake light no longer work

Good day, I have the problem that with my scooter (Kreidler China 2 Stroke) the turn signals, the horn, the E-starter and the brake light with switched ignition no longer work. As soon as the engine runs (E starter relay with screwdriver over –> So can’t be the battery) the horn and the brake light and the normal light without problems, the turn signals do nothing again. I honestly don’t know what it is because I had everything apart today and all Ka In addition, I have to say that colleagues had unnecessarily removed my ignition lock cable, after that the problem started. But actually it can’t be related to it, can it? It’s on it again. The scooter somehow didn’t find any fuses, at least in no form.
