Abstract
An ignition system for an internal combustion engine includes an igniter having at least two high voltage (HV) electrodes and a low voltage (LV) electrode. The at least two HV electrodes are electrically isolated one from the other and the at least two HV electrodes are electrically isolated from the LV electrode. The system includes a coil assembly having at least one primary winding and at least two secondary windings, each secondary winding having a terminal for providing a HV signal. A driver module is provided for energizing the coil assembly. A high-tension cable, comprising at least two resistive wires, connects the at least two HV electrodes to the terminals of respective ones of the at least two secondary windings. The high-tension cable further comprises a non-resistive wire connecting the LV electrode to the driver module.
