I can see where detaching that inductive load could give very big voltage spikes. It would generate a voltage V_L = L * di/dt. So the inductance times the rate of change of the current (from trying to break the current - from the detached load) would cause the inductance's changing magnetic field to collapse quickly, changing the voltage drastically in an attempt to maintain that same original current. The rate of change of the current (di/dt) is the real thing that causes the voltage to go through the ceiling forcing the inductance field to collapse. Thanks guys - you made me think in my retirement years.
