ABSTRACT:
A spark ignition engine tester for inserting between pairs of normally interconnected releasable connectors in the high voltage portion of the engine's spark ignition system, as between a spark plug terminal and the corresponding wire from the distributor, and between the high voltage output terminal of the coil and the wire to the distributor. The tester includes first and second electrodes with adjacent ends separated by a visible spark gap and remote ends for connection to the ignition system high voltage portion. An insulator supports the two electrodes substantially at right angles to each other. A conductive coil spring sleeved over the remote end of an electrode inserts into or sleeves over the opposed releasable connector of the emission system high voltage portion.
