      Mep 3 kW. 3 phase.
      During run time developed a rotating very disturbing noise .
      All functions run well full voltage ok
      Also during shutdown after engine stops rotating this odd and added noise continues for a few seconds more until stop
      What the heck is this Bearings? Brushes ?
      It’s like metal on metal Scraping
      I checked the oil in full. No metal flakes at all very clean
      Is this engine noise or generator noise
      Some one must have had this symptom before ????

      Did you have any luck fixing your generator ?Sounds like the flywheel is coming loose.
