Engine starter protecting device

摘要

An engine starter protecting device which prevents engagement of the starter's pinion with the ring gear of the engine, even when the engine is rotating. Sensors detect when the gear shift lever is in the neutral position, when the frequency of the ignition pulses for the engine is above a predetermined value, when the vacuum pressure of the intake air to the engine is at or below a predetermined value, when the vacuum pressure of the intake air to the engine is at or below a predetermined value, and when the output voltage from the alternator of the invention exceeds a predetermined voltage. The electromagnetic switch which controls the starter motor is prevented from operating unless the outputs from the detectors are in predetermined states.
