Abstract
A coil-on plug testing apparatus for detecting a weak field output by a shielded coil-on plug ignition and generating an output signal representing an ignition signal includes a capacitive sensor attachable to a coil-on-plug device for detecting an electric field generated by the shielded coil-on plug device during a firing event and generating and outputting a voltage in response thereto. A signal processing circuit electrically coupled to the capacitive sensor is configured to generate an output signal in response to variations in the voltage output by the capacitive sensor in response to a detected electric field. The signal processing circuit comprises an amplifier configured to amplify an output voltage of the capacitive sensor.
