as long as the ohmage is within the range, what would make a coil company say its not for use with a capacitive discharge ignition??
your thoughts?
BTW - coil is a pertronix flame thrower 1.5 ohm.
because a "coil" is used with a Kettering battery-condenser ignition as an energy storage device. a BIG part of its functionality is that it builds an electromagnetic field and has a big core to act as an every storage device. it charges while the points are closed, and then, when the points open and the electromagnet stops being a magnet, the collapsing electrical field is multiplied by the secondary windings to create the high voltage spark.
while there's crossover - some devices do both jobs marginally well - a CDI "coil" is not a coil -- it is a pulse transformer. it doesn't have to have a big iron core to act as a storage device. it's JUST a transformer.
so there's a whole lot more to the story than the resistance of the primary winding.
a "coil" is designed to work on 12 volts - it's charged from battery current. a pulse transformer is typically fed high-inrush currents at 300 VDC or better. coils designed to work on 12V (insulation comes to mind...) are not designed to have big pulses at 300V dumped in in a hurry.
it might work for a while - until the smoke comes out...
people run their Bosch Blue coils with mallory CDI's all the time. why cant i run a hotter coil with the CDI?? without buying the CDI 'pulse transformer' which they still call a coil...??
