Hi Mirco, you have to prove that the sweet potatoes and the induced are not short, that the bushings do not have a game and the length of the brushes is enough to have a good contact, that the solenoid works well by calling the Bendix and that the Blessed Blessed himself does not skate when entering the crown, I hope you help you, greetings.
If you try it outside it in a battery, the body of the start is land, and you feed it with a positive cable from the battery to the solenoid terminal where the battery is ba, then you make a bridge with the remaining terminal, let go and turn if it does not come out it is the induced fault if it does not rotate are the coals that is the basic, then the Bendix is going to be blessed for a single side.
