Hi all In a car old points ignition system, I understand the capacitor (condenser) main purpose is that of protecting the points from getting burnt. The second purpose for this capacitor, could it be to make a resonant circuit among the ignition coil in order to prevent it from radiation?. I mean the coil-condenser would make the system to oscillate at a lower frequency in the way that all the energy would be used to ignite the spark and there would be no loss in the case of a high frecuency radiation. Am I wrong? Another question. In what way does this capacitor help the primary coil to get those some 200 volts? Thanks a lot in advance.
