I have found theuse this method to find correct coils and their polarity as follows.of the coils: With all six end loose, use a continuity meter to pair up each of the coils two ends.
Use a controlled DC supply across each coil and inject a small DC current. Then take a simple magnetic compass and place it near each of the three coils.
If the direction of current flow is the same through each coil, the magnetic compass should give the same pole(north or south)near each coil. You can decide which of each end is start and finish end of the coils. Credit to A.Mizzi
