2.1 GENERATOR CONTROL PANEL
The following features are mounted on the generator control panel
(Figure 2.1):
Figure 2.1 – Generator Control Panel
2.1.1 FUEL PRIMER ‹
Before starting a cold engine (if it has not been started in more
than two weeks), this switch must be pressed for approximately
10 to 15 seconds to bring fuel from the tank to the carburetor.
This rocker type switch springs back into its original position
when released. It is not necessary to press the primer switch for
LP units.
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 center position is the RUN position.
2.1.3 FUSE ‹
The 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 replaxed, use
only an identical replacement.
2.1.4 MAIN BREAKER ‹
The 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
one 20-amp breaker and one 30-amp breaker.
NOTE:
If the generator has been reconnected for dual voltage AC out-
put (120/240 volts), install line breakers having an amperage
rating that is different than that stated in the "Generator AC
Connection System" section. The replacement line breakers
consist of two separate breakers (one 20 amp, and one 30
amp) with a connecting piece between the breaker handles (so
that both breakers will operate at the same time). If the unit is
reconnected for dual voltage, it is no longer RVIA listed.
2.2 OPTIONAL REMOTE
START/STOP PANEL
A remote mounted Start/Stop Panel (Figure 2.2) is available that
allows starting and stopping the generator engine conveniently
from inside the vehicle. The remote panel includes a Start/Stop
switch, hourmeter, generator run lamp and a wire harness. The
Prime switch is not connected, it must be used with jumper wire
0G7666.

2.3 AUTOMATIC CHOKE
(GASOLINE
ONLY)
The engine is equipped with an automatic choke that consists of
two main components: a choke solenoid and prechoke.
2.3.1 CHOKE SOLENOID ‹
During engine cranking (Start/Stop switch at START), a solid-state
choke module signals the choke solenoid to activate and cycle
(choke on/choke off) until the engine starts. The choke solenoid
thus opens and closes the carburetor choke valve only when the
engine is cranking. When the engine starts, the choke stops
cycling.
2.3.2 PRECHOKE ‹
The choke system also has a temperature-sensitive metal strip that
adjusts choke valve angle according to ambient temperatures (i.e.,
in cold ambient temperatures, choke valve closes more). Once the
engine starts, an element heats the temperature-sensitive strip to
a normal operating condition, opening the choke valve. This may
take about three minutes in cooler weather.
