That's really interesting, I was wondering about the possibility of
A/ swapping the alternator stator out for a 3 phase style or
B/ simply re-winding the existing stator as a 3 phase. It would be possible to do either in theory.
A/ I think it would be easier to find a rotor and stator about the same overall size and machine it down to fit.
B/ I think the existing rotor has 14 coils and I assune 14 slots, it's a little bit hard to distribute 3 coils evenly across that many however I'm not a motor winder, there may be a way.
When my regulator was playing up I tried just using a bridge rectifier in it's place. The resulting Voltage was a way too high leading me to believe the existing alternator has lots of capacity. I will try to get my prototype regulator together over the next couple of weeks to see if it takes care of the issue. I am using 50 Amp components.

Could you make a schematic of the single phase charging system & voltage regulator for this setup or have you done his already ?
