My fight (cramp) with the starter

Have finished my scooter (Baotian) for the summer, so maintenance. Everything in locating,only the e-starter is not possible,but this has been for a long time,but didn’t bother me,because the scooter starts with 1-2 times kicking. I don’t know what came in my head,but look why the starter doesn’t work? A large construction site was built up until the whole fairing parts were dismantled. Starter relay on the load cables bridged, starter goes. Control from the relay, brake pulled arrives 12,6 V,Start he pressed other side 12,6 V but doesn’t attract.Magnet switch broken? Have some more,but the same game. Taked 1.5 light cable,you can put it nicely in the back plug and start directly on a battery,Roller. I stood like an ox in front of the mountain, everything goes,the control etc.,just he just doesn’t start. No matter what and where I measured,I didn’t find the mistake and yet it was quite simple. What do you think it was about? Resolution tonight!
