ABSTRACT:
An ignition timing controlling apparatus which is supplied electric current by a relay circuit for backing up and outputs an ignition control signal instructing ignition to an ignition unit in association with a detecting signal of a rotation sensor. Further, the apparatus stops output of the ignition control signal at the stopping time of the engine due to an open state of an ignition switch and prevents the ignition unit from being ignited earlier than desired at the starting time when the ignition switch is in a closed state again, by detecting the open and closed state of the ignition switch and by not outputting the ignition control signal when the ignition switch is in the open state.
