b. Engine Starting and Stopping. The Engine Starting System uses the stored electrical energy of the batteries to
the turn the starting motor. When the master power switch (1, Figure 1-10) is positioned to on and the starter
pushbutton switch (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.
