it's the same as the spark plug circuit on the ignition.

It's not AC, it's pulsed DC.

Using a viberator is differant than the opening and closing of the points of
an engine. By the way that diagram is not correct. "The condenser goes

down the colapsing of the magnetic field which produces the other half of
the AC waveform.
