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