"WebIf 3 wires have continuity, then you probably have a center-tap winding (+, 0, -) If only 2 wires have continuity, then that is a simple winding. If 4 or more wires have continuity, then you have a multi-tap transformer winding. Transformer windings have a phase relationship, but it's typically not important for power supplies.
