Bill does raise the good question as to how low voltage a Pertronix will work
at.
The Pertronix web page states 8-16v. The fact that the lower limit is 8 volts
is almost conclusive that
the Ignitor is using a MOSFET to fire the coil (as opposed to a power
transistor).
While at the Pertronix web page I notice the Ignitor II, looks pretty cool
with the variable dwell
and built in over current protection. That might mean the little
micro-controller detects the motor not
turning and ignition switch left on, and switches off the current to the coil.
A worhtwhile feature.
