Figure 1-10. Engine Starting System.
b. Engine Starting and Stopping. The Engine Starting System uses the stored electrical energy of the batteries to
turn the starting motor. When the master power switch (1, Figure 1-10) is positioned to on and the starter pushbutton
(2) is depressed, electrical power passes through the starter pushbutton to the auxiliary starter solenoid. The auxiliary
starter solenoid draws electrical power directly from the batteries and sends it to the starting motor solenoid. When
the starting motor solenoid is energized, electrical power from the batteries is supplied to the starting motor and the
engine begins cranking. Positioning the master power switch to off stops the engine.
