Another thing which is only the theory but it bears an explaination . An magneto  ignition coil generates AC voltage but since it is only on the positive side of ground it's called pulsating DC .

It has the same sinosoidal wave form as AC .The trigger device fires the coil when it detects a negative transition in the wave form by an assortment of transistors ,capacitors and a bunch of electronic gooblede goo .

Nice to know info maybe but for all intents you can't do much with a solid state coil other than replace it if it doesn't work .
