    I dug out my Force manual. In “theory of operation,” it says, “the inner hub also has a set of magnets that generate AC voltage.” So, it implies I’m wrong about one magnet; but it doesn’t really elaborate much more than that.

    Book says trigger resistance is between the violet and white wires and between the brown and black wires; and it should be between 700 and 1000 ohms. Your 850 is pretty darn perfect….DVA running tests are the real way to go on these ignitions.

    Long live American manufacturing!
