Actually, as I understand it (please correct me if I'm wrong) the coil
is in essence a large capacitor, whose fucntion is to hold a charge
until such time as there is a path to ground. So the charge would in
fact sit ( in the capacitor, not the rotor though) until the rotor came
around and made contact with cap, wich provides the charge in the
capacitor (ignition coil) with a path to ground ( via the spark plug).
Boom, plug fires.
