I tried this on multiple ignition wires with no results on picking up any signal with the meter.

I was looking for a tach adapter to quickly set RPM's on small engines with out having to wrap a wire or put reflective tape on the engine. Seemed to be OK for the first couple, now gives readings all over the place. I just gave up on it.

Total waste if your car uses coil on plug (cop) ignition. No way to hook it up!
