Possibly More important, as Pertronix specifically warns against doing so.
Same problem as points; if the circuit is closed and the engine stopped,
then current is flowing constantly instead of only half the time, doubling
the average current.  The points, coil & Pertronix are all apt to overheat
under such treatment, but the Pertronix will likely melt first ... or at
least have a shortened lifetime.
