19. Discharge Pressure Gage
The discharge pressure gage (9, fig. 11) is located at the
lower right of the instrument panel. It indicates pressures
on the discharge side of the pump. Normal gage readings
are from 0 to 300 psi.
20. Magneto Switch
The magneto switch (10, fig. 11) is located at the lower
center of the instrument panel. When pulled out it closes
the magneto circuit. Pull out before starting the engine.
Push in to shut off the engine.
21. Starter Button
The starter button (11, fig. 11) is located at the lower
center of the instrument panel. When depressed, it
completes a circuit that actuates the starter solenoid.
W hen the starter solenoid is closed, a circuit from the
batteries to the starting motor is completed, and the
starting motor cranks the engine. Both solenoid and
starting motor circuits are broken when the starter button
is released.
