10-2 OPERATING PRINCIPLES
The battery is connected to the 8 mm diameter terminal of the magnetic switch.
The figure below shows the state when the starter is ON.
There are two energized circuits: the magnetic switch (M) circuit and the starter motor (S) circuit. When the
key switch is ON, the (M) circuit is closed, the current flows in the direction of the arrows, the coil of the
magnetic switch is magnetically excited and the contactor is pulled.
As a result, a low current flows through the (M) circuit and a high starter current flows through the (S) circuit.
This energizes the starter motor and cranks the engine.
◇ Engagement of the pinion gear
When the starter motor is started, the weight built into the spiral splines located on the shaft moves in the
direction of the axis driven by centrifugal force and pushes out the pinion gear, and the pinion gear
engages the ring gear.
