ABSTRACT:
An engine spark ignition system capacitive coupler for capacitively coupling the non-firing spark plug wires to the firing spark plug wire. The device includes a first plate having a first side and a second side, the first side having at least two spaced, electrically conductive surface portions, each surface portion forming a first plate of a capacitor. A second plate of each capacitor is formed by an electrically conductive surface portion disposed in spaced and insulated relationship to the at least two surface portions upon the second side of the first plate. A second plate alignable and abuttable to the first plate and having first and second sides is abuttable to the first plate first side. At least two spaced electrically conductive members are disposed through the second plate. Each conductive member includes a first end for electrical contact with a spark plug wire and a second end for electrical contact with one of the at least two first plate, first side electrically conductive surface portions. A retaining plate is alignable with the second plate and is abuttable to the spark plug wires to retain them in electrical contact with the first ends of the conductive members. A base plate alignable and abuttable to the first plate and having first and second sides is abuttable to the first plate second side. An electrically conductive member is disposed through the base plate. The base plate electrically conductive member includes a first end for electrical contact with the first plate, second side electrically conductive surface portion and a second end disposed adjacent the base plate second side. A bolt is receivable through a threaded bore formed in the center of the retaining plate, a bore formed in the second plate, a bore formed in the first plate, and a threaded bore formed in the base plate to alignably attach the plates together.
