OPERATION
The major portion of electrical power in your Airstream is 12-volt. The 12-volt
current powers the vents, furnace, water pump, and water heater ignition. The
exceptions would be the air conditioner and microwave oven.
All 12-volt current comes through the battery system in the front of your trailer.
The battery is accessible in the battery box on the A-frame of your trailer. Power
from the battery goes to a set of four Type 2 thermal breakers located under
the roadside front bed and riveted to the interior skin. The breakers are tied
together by a brass bus bar. One breaker (30 Amp.) protects the 12-volt tow
vehicle charge line coming from the 7-way cord. Another breaker (20 Amp.)
feeds the trailer brakes breakaway switch located near the hitch coupler. A
50-amp breaker feeds the Battery Disconnect relay. The current leaves the
relay and goes to the 12-volt distribution panel located in the converter and
then to the rest of the trailer. Open the decorative door on the front of the
converter to access the panel and its fuses. A 12-volt circuit diagram is shown
later in this section.
If you replace a blown fuse and it immediately blows again, do not replace the
fuse again until a qualified service technician can correct the problem.
If the replacement fuse holds for a week or more and the gap in the fusible metal
is barely melted apart it usually indicates an overload condition. Reducing the
number of lights or appliances used on that particular circuit at the same time
could prevent any further fuse failure.
BATTERY DISCONNECT SWITCH
The manual disconnect switch is used to separate the battery from the 12-volt
distribution panel and converter charging system. Disconnecting the battery
will help prevent battery discharge during storage periods from safety equip-
ment, radio memories, and appliance electronic boards.
The switch is located on the front of the roadside bed on the 22’ model and the
front of the roadside Dinette seat on the 16’ model.
When the switch is turned on and the trailer is plugged into a 110-volt shore-
line, the 12-volt distribution panel will receive power from the converter and the
battery will be charged through the converter charging system.
