should be checked and replaced, when necessary,
with a new bulb of the same size. A failure of
more than one light, such as both taillights not
operating, may indicate a burned out fuse. Check
fuse and replace with one of the same rating
when necessary. If a fuse is not the cause of the
problem, the wiring system should be checked
immediately by an authorized service center.
The headlight circuit is protected by a circuit
breaker. An overload on the breaker will cause
the lights to flicker on and off. Headlight wiring
should be checked immediately anytime this
condition is apparent. Refer to your chassis
operating guide for further information.
AUTOMOTIVE 12-VOLT FUSES
AND CIRCUIT BREAKERS
The automotive fuses and breakers are
conveniently located on a panel beneath the
hinged instrument panel pod. Lift the pod upward
as shown.
The circuit breakers will pop outward if they
are tripped. Simply push in to reset.
Always replace plug-in type fuses with those
of the same amperage size.
TOWING GUIDELINES
Gross Vehicle Weight Rating
(GVWR):
This is the maximum allowable weight of the
fully loaded vehicle. Included are fuel, water, LP,
passengers, cargo, tools, and optional equipment
installed by the motor home manufacturer,
dealer, or owner. This value is found on the VIN
label, typically placed near the driver position.
Gross Axle Weight Rating (GAWR):
This is the total weight a given axle is capable
of carrying, measured at the ground. Each axle
has its own rating. These values are also found on
the VIN label: front, rear, and tag, if applicable.
Gross Combination Weight Rating
(GCWR):
This is the maximum allowable weight of the
motor home and loaded trailer, including the
items noted in GVWR above. The “trailer” can
be an actual trailer, a vehicle towed on a towing
dolly, or a vehicle towed by means of a towing
bar. GCWR is typically specified based on
durability and performance of the tow vehicle
drivetrain: engine cooling systems, transmission,
drive line, drive axle, and others. The tow vehicle
brakes may be rated for operation at GVWR, not
GCWR.
NOTE: If the “trailer” weighs 1,000 lbs. or
more, state or provincial laws/
regulations may require the “trailer” to
be equipped with brakes that are
activated when the motor home brakes
are applied.
