Re: stepper

1-6 and 3
1 and 6 are the highest resistance so are at ends. 3 is the center

2-4 and 5
2 is the center
4 to 5 are the high resistance so are the ends.

series is 1 to 6 for one circuit and 4 to 5 on the other.

For single coil, 3 to 1 OR 3 to 6 for one coil
For the other coil of a single coil, 2 to 4 OR 2 to 5.

Isolate the unused wires, do not connect them to anything.
