Abstract
A signal source for use in a breakerless ignition system for an internal combustion engine, comprising a stator having a plurality of normally igniting signal coils arranged so that they produce respective ignition timing signals at respective ignition points slightly different from each other, said normally igniting signal coils being operatively associated with a breakerless ignition system so that the ignition timing signals are supplied thereto and having said respective ignition timing signals selectively applied in response to increase in the revolution number of an internal combustion engine, said signal source characterized by further comprising a starting signal coil positioned to produce a starting signal at the ignition point advanced in phase relative to some of said normally igniting signal coils relatively retarded in phase and operated when said engine is started at a relatively lower speed, said starting signal coil operatively associated with said breakerless ignition system so that said starting signal is supplied thereto; and switching means associated with said starting signal coil to by-pass said signal from said ignition system when the starting of said engine is completed.
