Robert,
I also think that the current is finding a path through the
distributor cap from the center connector (the coil output) to the spark
plug wires. I would bet that both plugs are sparking at the same time,
but only the one at TDC fires. The motor runs, but probably not that
well. I don't think it is really necessary to find the short through the
cap (which could be just a little moisture or dirt). It is not necessary
because when the rotor is in the distributor, a path through the cap
will not be used because there is a low resistance path through the
rotor. Also, only one cylinder will fire at a time because there will
only be one low resistance path at a time.
