Yes, this again.
I would be connecting the center tap (yellow and white) to my +12V and grounding the remaining wires with NPN transistors. I want to use a wave drive sequence:
0001 0010 0100 1000
I just don't know which wire is what!
I think this is equivalent:
BLK BLU GRN RED
I thought I had it figured but it's not working. I'm trying to troubleshoot if it's my circuit or my step sequence.
