Section 2 – Operation
PRIMEPACT 55G and 55LP Recreational Vehicle Generators
• For engines of 225 cc or more, Category C=250
hours, B=500 hours, and A=1000 hours.
2.1 GENERATOR CONTROL PANEL
The following features are mounted on the generator
control panel (Figure 2.1):

2.1.1 FUEL PRIMER

Before starting a cold engine (if it has not been start-
ed in more than two weeks), you must press this
switch for approximately 10 seconds to bring fuel
from the tank to the fuel pump. This rocker type
switch springs back into its original position when
you release it.

2.1.2 START/STOP SWITCH

To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating 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 15 AMP 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 you must replace the fuse, use only an
identical 15 amp replacement fuse.

2.1.4 LINE B REAKERS

Protects generator’s AC output circuit against
overload, i.e., prevents unit from exceeding
wattage/amperage capacity. This unit has one 20-amp
and one 30-amp breaker.

Figure 2.1 – Typical Control Panel

NOTE:
If this generator has been reconnected for dual
voltage AC output (120/240 volts), you can install
line breakers having an amperage rating that is
different than that stated above. The replacement
line breakers consist of two separate breakers 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 REMOTESTART/STOP PANEL
A remote mounted Start/Stop Panel (Figure 2.2) is
available that allows you to start and stop the gener-
ator engine conveniently from inside the vehicle. The
remote panel includes a Start/Stop switch, hourme-
ter, generator run lamp and a wire harness.

2.3 AUTOMATIC CHOKE
This 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.
