It occurred to me last night while I was working through some wiring diagrams for an ignition problem that I put an error in this advice to Pete. It is always the - (ground) side of the ignition coil that is switched, so it is the - side of the ignition coil that would be used as a tach signal and the equivalent of the "P-lead" from a magneto as a source for wiring the tach signal. I'm surprised about a half a dozen of the scholars here didn't correct me.
