Uh, no. Middle is power in, it goes out to either side, the primary pairs. Connecting through in any combination should register very low there. Middle through either side is one primary worth of resistance, two outsides to each other double the primary resistance which is still relatively low.

Plugged or unplugged will not affect how coil is hardwired.................
