Very high resistance in rebuild windgen (Fourwinds II)

I have (or had?) a 1999 Fourwinds II. I started making noise in low rpm so time for the periodic overhaul. When I put everything back together however she hardly turned. It is NOT the ball bearings but it is as if the electro-magnetic field works against the turning; the faster I want to turn the stronger the resistance. When one takes the magnets (glued to the housing) away, she spins happily. I turned the housing around (so front to the back and vice versa) NO difference. I had somebody measure the core around the shaft: everything seems to work fine (no short). Does anybody have any idea? Thanks! Arjan

It sounds like it is delivering power under a load. Check for a short, either in the internal wiring, as you had it apart.

I know you said you tested for a short but I can't see how it can be anything else
