Hi NTL.
I normaly take the exsisting motor conection wires and start with one. Next I follow through the coil its conected to and on through the next coil that it connects to. Then make a cut there. 2 coils then cut.
For 12 volt use on the Garbogen it works best to wire 2 run coils in sires and then perelell them with the other 2 run coils. Do the same for the starts.
Use seperate bridges on the runs and the starts. This makes for a 2 phase PMA.
The start of the first 2 coils connects to the start of the second set of coils.
The end of the first 2 coils connects to the end of the second set of coils.
This makes the sires/perelell circut above.
