Electrical
12-Volt System
The major portion of electrical power in your Airstream
is 12 volt� The 12-volt current powers almost every
thing except the roof A/C, water heater, 120-volt
receptacles, and microwave oven� However, some of
these appliances have 12-volt electronic boards�
All 12-volt current is routed to a 12-volt pass-through
power stud mounted on the battery box� The power
stud is the hub of the 12-volt system� It ties together
the inverter/charger, house battery, and battery
separator�
Power from the stud goes to a buss bar with four
breaker positions holding Type 2 thermal breakers�
The thermal breakers feed the rear lounge motor, the
tank heater pads, and the battery disconnect switch�
A position is left open to add a breaker for an optional
solar panel�
Power is routed from the battery disconnect switch to
the 12-volt distribution panel and through its branch
circuits to the rest of the touring coach�
CAUTION
Thermal breakers break contact when overheated
by a short or overload in the wiring. These
breakers automatically reset when cooled down.
A breaker continually overheating and breaking
contact should be investigated by a qualied
service technician.
12-Volt Operation
The only thing you have to do is make sure the house
battery does not run down� In normal usage this
shouldn’t be a problem since you would normally be
plugged into an external AC power source at night or
when camping� When you’re plugged into shoreline
power or running the generator the inverter/charger
charges the battery and carries much of the load�
Some nights you may not nd a place to plug into
city power� This should not be a problem; you can
comfortably run your lights, water pump, and vents in a
normal fashion without depleting the battery�
If you are not plugged into city power, and you plan
on staying longer than a day or two, you’ll want to
conserve your battery by using as few lights and
appliances as possible� Check the monitor system
regularly� If you notice the lights becoming dim, it’s
much easier on the battery if you start the generator or
run the chassis engine before the battery runs down�
Power Shades
All Interstate models come with power shades
controlled by the Multiplex Systems touch screen
control panels located in the front and rear of the
touring coach� The shades feature a mechanical limit
switch to prevent accidental loss or change of limits
due to power surges or power outages� The shades
will retain their pre-set limit stops even if the shade is
pulled down manually by mistake� These presets are
set at Airstream and shouldn’t need adjusted�
The multiplex panels allow for control over individual
shades as well as a master control button to raise or
lower all the shades at once� Pressing either the up or
down arrow next to the shade you want to control will
raise or lower the shade� If the same arrow is pressed
before the shade reaches its pre-set limit stop the
shade will stop at its current position�
Refer to the Power Shades owner’s manual for tips on
cleaning�
Storage Tips
Galley cabinets should have the heaviest items
stored on the bottom and lighter items overhead� After
loading, put skillets and canned goods on the oor or
bottom shelf, and cereals and crackers in the overhead
roof locker� Use unbreakable-type plates and saucers,
and consider storing your dish towels around them�
Clothes hung in wardrobes should be kept on hangers
that snap over the clothes rods to keep them from
bouncing off on rough roads� Try to avoid large bulky
coats� Layers of lighter clothing will usually keep you
warmer, are more versatile, and are easier to store�
WARNING
Keep ammable material away from the furnace.
