Thanks, so that means that the resistance between wires 5 and 1, 5/2, 5/3 and 5/4 would be the same, while the resistances between other combinations (i.e. 1/2, 2/4 etc) would differ.
I did read somewhere in Lin Engineering that the hybrid 6 wire 5718L series motors (my motors) can be connected as either a unipolar 6 wire or bipolar 5 wire but cannot find the references anymore. Will go looking.
I'll check the wire harness to see if wire config has been changed between the motors and the board.
