if two windings are in series for each phase the star point should have 3 wires not 6.(see high wye)
The extra 3 wires are a mystery to me.

I guess all you can do is test all 6 windings are making power and that the correct pairs are joined together.

I'm confused, no wait... maybe I'm not...

Dear friend but if you look the factory diagrham i find 4 phases and 8 coils for each phases
every ciol is spaced to 5 slot !

how it can work tree phases if there is 4 phases every 45 ° instead 120 ???

if you try to build and winding in a 33 slot stator every 5 slot this is the result
