contrast, the alternator is not charging the battery when the nee-
dle points to the (-) negative side of ammeter. If this happens,
repair the charging system to prevent discharge of the battery.
Temperature Switch/Gauge and Reset Button (Fig. 7)—The
temperature switch/gauge registers the temperature of the
coolant in the cooling system. If the coolant temperature gets
too high, the engine will shut off automatically. When this hap-
pens, turn the ignition key to OFF. Automatic shut-off of the
engine usually results from debris on the front of the screen or
the radiator, which reduces air flow. After cleaning the outside
of the screen and radiator or repairing some other damage, press
the reset button and start the engine.
Glow Plug Switch and Indicator (Fig. 7)—Use to preheat the
engine cylinders before and during starting procedures. Push
the switch lever upward and hold while watching the indicator.
The indicator will glow red when sufficiently heated. The time
necessary to preheat cylinders is determined by atmospheric
temperature; refer to Starting and Stopping The Engine.
Key Switch (Fig. 7)—The key switch is used to start and stop
the engine. It has three positions: OFF, RUN and START. Turn
it clockwise to the START position to engage the starter motor.
When the engine starts, release the key and it will move auto-
matically to the ON position. To shut the engine off, turn the
key counterclockwise to OFF.
Throttle Control (Fig. 7)—The throttle is used to operate the
engine at various speeds. Moving the throttle forward increases
the engine speed—FAST; backward decreases the engine
speed—SLOW. The throttle regulates the speed of the cutter
blades or other implement components and, together with the
traction pedal, controls the vehicle's ground speed.
Electrical System Fuses (Fig. 8)—An engine temperature reset
relay fuse—SFE 14-amp—is located at the rear of the reset
relay. An in-line fuse—AGC 10-amp—is also incorporated to
protect the engine control module. The fuses can be accessed
by removing the instrument panel cover.
A 40-amp circuit breaker is also incorporated to protect the
entire wiring circuit. A reset button is located on the lower side
of the panel, which can be reached after removing the battery
cover (Fig. 9). The button should be depressed if a total loss of
all electrical functions should occur. However, the electrical
system should first be checked to find the reason for the mal-
function.
