Re: Ignition Analyzer?

I use one of these a lot and LOVE the thing. It works on anything with plug wires but not on modern, coil-over-plug systems. Once you get used to using it, you can tell whether a cylinder is fouled, rich or lean, besides whether it is just firing or not. I have made otherwise very good mechanics look like idiots in five minutes, with this thing.

Edit: Keep in mind, though, that it works only when an engine is running. It will NOT practically test for spark on a dead engine.

Long live American manufacturing!
