Abstract
The present invention is addressed to an exciter circuit used as part of an engine ignition system which is controlled by a full authority digital engine control or FADEC. Two channels of the FADEC system are connected to two channels on the exciter system in a cross talk arrangement. This permits any one channel on the FADEC to control both channels on the exciter for redundancy purposes. The establishment of a FADEC control of an exciter system also permits selective use of the exciters and reduces wear on the exciter circuitry and ignition system components.
