uups sorry my mistake - it was wrong to measure against ground ...
To verify a 3 phase stator : (phase 1,2,3)
1.) verify that phase 1,2,3 has no connection to ground
2.) verify that 1-2, 2-3, 1-3 has the same resistance (0,04 Ohm in my case)
3.) run the engine, rectifier unplugged and verify that: 1-2, 2-3, 1-3 has the same voltage, in my case around 18V when idling
so my stator is o.k. - seems I need a new rectifier following the hints before - Thanks!
