2.1.2 7.5 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 the fuse must be replaced, use
only an identical 7.5 amp replacement fuse.
2.1.3 LINE BREAKERS
Protects generator's AC output circuit against overload, i.e., pre-
vents unit from exceeding wattage/amperage capacity. The circuit
breaker ratings are as follows:
Model Cir. Breaker 1
RV45 20A
RV55 20A
RV65 30A
If this generator has been reconnected for dual volt-
age AC output (120/240 volts), install line breakers
having an amperage rating equal to that stated in the
preceding chart. The replacement line breakers con-
sist 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 recon-
nected for dual voltage, it is no longer RVIA listed.
2.1.4 DIAGNOSTICS
If the generator shuts down due to a fault, the indicator will flash a
code to identify the problem.
• 2 Flashes = Low Battery (Voltage falls below 11.0 VDC for one
minute)
Alarm will clear automatically if voltage rises over
11.0 VDC. Battery voltage is not monitored during
crank cycle.
• 3 Flashes = Overcrank (Unit does not start through entire start
cycle)
• 4 Flashes = Overspeed (Alternator spins at 4200 rpm/72 Hz
or greater)
• 5 Flashes = Low Oil Pressure (Drops below the 5 psi threshold
of the switch)
There is a five second delay of the alarm when the
engine is first started up.
• 6 Flashes = High Oil Temperature (Unit shuts down when tem-
perature switch limit is reached)

NOTE:
NOTE:
NOTE:
As the unit cools down it will attempt to restart auto-
matically when the temperature switch opens again.
• 7 Flashes = Underspeed (Alternator spins less than 3240
rpm/54 Hz for three (3) seconds)
After a fault is indicated, press stop momentarily to
clear the alarm once the problem is fixed.
2.2 OPTIONAL REMOTE
START/STOP PANEL
A remote mounted Start/Stop Panel is available that allows start-
ing 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.
2.3

AUTOMATIC CHOKE

This engine is equipped with an automatic choke that consists of
two main components: a choke solenoid and prechoke (Gasoline
only.).
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 (Gasoline only.).
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 (Gasoline only.).
2.4 BEFORE STARTING THE
ENGINE
Instructions and information in this manual assume
the generator has been properly installed, con-
nected, serviced, tested and adjusted by a qualified
installation technician or installation contractor.
2.4.1 INSTALLATION
Generator installation must have been properly completed so it
complies with all applicable codes, standards and regulations
and with the manufacturer's recommendations. (See Part II -
Installation Instructions.)
