Hi 
      would anyone happen to know the resistance readings for the windings ..both ignition and lighting .. on a European 1F9 DT125 or a 1N1 DT100 which according to their respective parts books have the same generators

Get onto this in the tech library & go down to page 7C page on its side just to be annoying. I've tried to save, copy, screen shot, with limited success but i'll load what i saved & maybe you can expand it. bit blurry but can make out the resistances ok. See how ya go.

Yep expand it & can make out the ignition source resistance & lighting charging resistance but be careful as the secondary coil--plug coil--is in there between just to confuse things.

Thanks very much for that
