I just read about getting 240v across both U and V to m5 it only should be from one of them at a time. without the contactor jumpers i asked about on the last post it could be putting the transformer in series with the windings and it would act like choke on the motor. That may be what is wrong. I'm going to print and modify the drawing to the way I think it should be. give me about 45 minutes and I'll get back.
You are correct in that I get 240v across U, V and M5 one at a time.
