i was reading about making your own home made ETM on ohiocaferacer.com last night and had a few questions. No, i am not up to my armpits in coil windings, just trying to understand a few things. The guy made reference to a primary and secondary coil. so, uh, my primary coil is the one under my tank, going to the spark plug? or is that the secondary with primary being on the stator? sounds like a cool trick, maybe a little much for my needs. just trying to learn.
