Scooter is a TPH 50. When I wanted to start yesterday by e-starter it didn’t work. Before that without the slightest problem. If I pressed either no noise or sometimes a very quiet and pitiful “plok” – as if the starter scribbling wanted to torture itself out. After many, many attempts I once managed to get the scooter to run by e-starter – but only once and never again. By kick it is no problem at all. There it is immediately on. The battery h I just measured again. It’s full of problems. Where should I start troubleshooting?
