Quoting Removed, click Modern View to seeLJD seems really hung up on a low resistance primary, but energy is 1/2 L X I X I, so energy can be increased either by more I or by more L.
It isn't a one trick pony. As for turns ratio, the very early SS igns used as high as a 400:1 turns ratio.......it wasn't to achieve a super high voltage, but rather it was a bandaid to be able to achieve a voltage as high as point systems could achieve with a 100:1 coil. Reason being, that the semiconductors available at the time couldn't survive the 200 to 400 volt primary voltages, so protection clamp diodes limited the primary to around 100 volts, thus to achieve 20K-40K secondary, they HAD to use 400:1 coils........it was a "fix" not a "feature". Just a bit of history.

Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
