ABSTRACT:
An electric starting system for cranking an internal combustion engine that utilizes a starter having a solenoid that is provided with pull-in and hold-in coils. The solenoid includes a plunger which when shifted operates solenoid switch contacts and shifts a pinion into mesh with the ring gear of the engine to be cranked. The solenoid switch contacts are not closed until the pinion is meshed with the ring gear. The electric starting motor is connected in series with the pull-in coil of the solenoid and when energized causes the armature of the motor to rotate slowly prior to the time that the pinion is meshed with the ring gear. The hold-in coil is not energized until the gears are meshed, which may be just prior to the solenoid switch closure to apply full power to the motor.
