	Ring the manufacturer? Start by pairing them off. Look for pairs that provide a continity reading to a multimeter. Then instead of 6 unknown leads, there will be three pairs. Report back for more ideas when this has been completed. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Perhaps I'm wrong, but I wouldn't have thought that would help him much, without identifying on the diagrams the points that represent the 6 leads. Please clarify. My first thought when I saw the original post was that if there are 6 leads it must be a 3-phase motor. __________________ Give masochists a fair crack of the whip

	Sometimes, the connection diagram is pasted, inside of the cover of the cable junction box of the motor.

	"motor using 110V/220V" Is this a dual supply feed/dual speed motor by any chance? Please confirm. "The motor have unmarked 6 lead." Are unmarked 6 leads terminated on connector studs or are some length of wire? How many capacitors do you find & what are their value? What are the color of the 6 leads?
