Final Words: All you have learnt the wiring color codes for both DC and AC (1 & 3-Phase Circuits) in IEC & NEC and other regional relations. If the voltage measured between B and D was 38V the windings are in anti-phase: if A is the start of A-B then C is the end of C-D. You can connect the windings this way to double the voltage or swap C and D to have the windings in phase again.
