volt converter, supplies power to the exterior an d
interior lights, the range hood fan and light, th e
furnace blower, water pump and porch light . Th e
12-volt energy is supplied by the automotive battery ,
RV battery or the power converter .
The automotive battery and alternator suppl y
12-volt power to the engine ignition system, th e
dashboard lights and accessories, headlights, tail -
lights, backup lights, clearance lights, turn signal s
and warning flasher lights . The automotive alternato r
also will charge the RV battery, although an isolato r
prevents the RV system from drawing power fro m
the automotive battery .
The RV battery supplies power to the furnac e
blower, water pump, power vent, range hood fa n
and light, interior 12-volt receptacles, interior lights ,
refrigerator and monitoring panel . The 12-vol t
receptacles can be used only for appliances specif-
ically designed for that type of energy . The R V
battery also is charged by the power converte r
whenever you are using a Shoreline connectio n
or generator .
AUXILIARY BATTERY — Check the liquid leve l
at least once a month . It must be above the plates.
The battery manufacturer approves using a good
grade of drinking water, excluding mineral water .
Keep terminals free of dirt and corrosion . Use a
hydrometer to check battery charge . When specifi c
gravity is below 1 .255, recharge the battery unti l
1 .260 is indicated .
CAUTION : If the battery must be "Quick
Charged", turn off the refrigerator.
CONVERTER — The power converter transform s
120-volt AC into 12-volt DC and supplies powe r
to all of the 12-volt systems except the refrigerato r
when it is supplied by a 120-volt source . Each 12-vol t
circuit is protected by a fuse in the Distribution
Panel which is wired to the converter . Raise th e
Distribution Panel door to expose the fuses . A listin g
of the circuits is next to each fuse . Some fuses
protect circuits with more than one function, others
may be for specific appliances . If a fuse breaks ,
turn off or unplug all appliances on that circuit .
Replace the broken fuse with one of the same amper e
rating . If the fuse continues to break, contact you r
GMC dealer .
GENERATO R
The optional generator (Figure 5) is a gasolin e
powered appliance which will supply 120-volt elec-
tricity while you are camped or traveling . A remote
generator START/STOP switch is mounted on th e
monitoring panel, beneath the generator running -
time meter. Another START/STOP switch is mounte d
on the generator . There is an Interlocking Devic e
attached to the circuit breakers for the Shoreline an d
Generator in the Service panel, which prevents th e
simultaneous use of both systems . When you push th e
Shoreline Breaker ON, the Interlocking Device
automatically pushes the Generator breaker OFF ,
and vice versa . You can, however, turn both breaker s
to OFF at the same time . Before starting your gener-
ator, switch both breakers to OFF .
Open the generator access door and depres s
the buttons on the two latches to slide out th e
generator . A safety latch (on the right side nea r
the top) just inside the front panel must be presse d
to allow the generator to slide all the way out . Thi s
safety latch also prevents the generator from acci-
dentally opening during travel .
The complete operation and maintenance pro-
cedures for your generator are in the generato r
manufacturer's manual, but below are a few of th e
basic requirements :
Make certain the generator crankcase oil is t o
the FULL mark ; that air flow to and from the power
plant is unobstructed, and that cooling fins ar e
clean . Push START/STOP switch to the start positio n
and hold until generator is running, then releas e
switch . Damage may result if starter is operated
for more than 30 seconds . Allow the generator t o
warm up before switching the circuit breaker in th e
Service panel to ON . To stop, press the START /
STOP switch to the stop position . If the generato r
has been running with a full load connected, switc h
the Generator and Shoreline circuit breakers OF F
and allow the generator to run a few minutes before
pushing stop switch .
Check the oil daily or at least every 8 hours o f
operating time . Clean the cooling fins at least ever y
200 hours ; remove any dust, dirt or
oil
which ma y
have accumulated . Change oil in a new generato r
after the first 25 hours of operating time and ever y
100 hours thereafter . Use oil specified in the manu-
facturer's manual . Change the oil filter every 20 0
hours . Check the air cleaner element every 100 hours ;
clean it by tapping it against a flat surface . Chang e
the air cleaning element at least every 400 hours .
The schedules above are only a guide ; when th e
generator is used in extremely dusty or cold condi-
tions, all maintenance steps may need to be more
frequent .
WARNING : When running, the engine powering
a generator can discharge carbon monoxide gas ,
which can cause death if inhaled even for a
short period. Although exhaust fumes are
usually readily evident, carbon monoxide is
particularly dangerous because it is colorless
and odorless. When operating a generator, D O
NOT open roof vents, windows or doors which
