2.1.1 HOURMETER
This indicates the length of time the engine/generator has operat-
ed, in hours and tenths of hours. Use the hourmeter to ensure that
the periodic maintenance tasks for the generator are completed on
a timely basis.
2.1.2 START/STOP SWITCH
To crank and start the engine, hold this switch in the START posi-
tion. Release the switch when the engine starts. To stop an operat-
ing engine, press and hold the switch in the STOP position until the
engine shuts off. The switch’s center position is the RUN position.
2.1.3 FUSE
The 15-amp fuse protects the engine’s DC control circuit against
electrical overload. If the fuse element has melted open due to
overloading, the engine cannot be cranked. If the fuse must be
replaced, use only an identical replacement (i.e., AGC-15).
 If a fuse element melts, find the cause of the
overload before replacing the fuse.
2.1.4 LINE BREAKER
The line (i.e., main) breaker protects the generator’s AC output
circuit against overload and provides a method of turning OFF the
generator’s 120/240-volt AC output to the vehicle circuits. The
generator has two 40-amp breakers.
NOTE:
Refer to section “Generator AC Connection System,”. Individual
installations will differ. If an overload occurs, the dual break-
ers will open the ungrounded (i.e., hot) stator leads (11 and
33 in Figure 1.1). When the generator has been connected
for 120/240 dual voltage (Figure 2.16), the line breakers will
operate on the ungrounded (i.e., hot) stator leads (11 and 44
in Figure 2.16).
2.1.5 PREHEAT SWITCH
The diesel engine is equipped with glow plugs, one for each cylin-
der. When the preheat switch is pressed, the glow plugs heat the
engine combustion chamber, allowing for quicker starts when the
engine is cold. Pressing the preheat switch also operates the fuel
pump.
