Granted that putting words together, making sentences, all to get a point across can be a bit inprecise at times. But, as I read your statement, it comes across to me that you claim the entire idea is fictional - not just in recent igntion coils.
You posed the question "Can you PROVE you've EVER seen EVEN ONE coil with an INTERNAL RESISTOR . . ."
You did NOT say one "newer" coil, or one "12 volt" coil.
Seeing how this forum has a primary focus on antique equipment, I didn't think 1930s - 1940s electrical systems were not included in the discussion. Also - about your most recent comment about the images I posted - and the resistors NOT being in the coils? I guess it depends on what you call "in." They certainly were considered part of the coil, but the coil top could be pried off for access to the internals. Go pick up an Oxford English Dictionary and look up the word "in", and I think you'll find it applies here. In regard to 12 volt coils, I have worked on many specifically referred to as internal resistor coils. I have some specs on `1960s - 1970s outboard motors and some British and German cars that go as far as give resistance specs just for the resistor inside the coil - separate from the primary and secondary windings. But, I can't say I've ever bothered to saw one in half just to look inside. Once the tops no longer popped off, I tended to just throw coils out when they stopped working.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
