to all other problems it seems that the generator produced not voltage to the batterie.

First thing to check is the regulator. (picture).

In and out is clear to so far, but what are the green and yellow wires good for ?

What does the green one, a 12V Lamp or a LED ?

What does the yellow one, the actual currant in V from the generator ?

Is there any V on the yellow one if the engine is off ?

please let me know.

Thank you all.

Hi steffen,

      the origional  jab alt / reg only puts out about 20 amps above 1000 rpm. you may want to look into the new b&c acv-1

regulator. or a rotec aftermarket 40 amp alt. for jabs.
