Abstract:
A coil-over-plug testing adapter system for use in combination with an engine analyzer, comprising:a capacitive pickup probe comprising a substantially planar first conductive layer and a substantially planar second conductive layer separated by a dielectric layer adapted to be placed over a coil-over-plug or coil-near-plug ignition assembly under test; an input port arranged to receive an ignition signal provided by the capacitive pickup probe when placed over a coil-over-plug or coil-near-plug ignition assembly under test; a variable gain controller configured to selectively modify said ignition signal received at the input port by at least one of amplification and attenuation to facilitate display of said ignition signal received from the tested coil-over-plug or coil-near-plug ignition assembly; a trigger pickup arranged to provide a timing signal from the coil-over-plug or coil-near-plug assembly to the adapter; and an output port arranged to output the signal modified by the gain controller and timing signal to an input to an engine analyzer.
