Battery/12-Volt System Information
The major portion of electrical power in your
Airstream is 12-volt� The 12-volt current powers all
gas appliances for controls and/or ignition as well as
lighting� An exception would be the range which has its
own ignition source�
All 12-volt current comes through the battery system
in the front of the trailer� The batteries are accessible
in the battery box on the A-frame of your trailer� Power
from the batteries goes to a set of Type 2 thermal
breakers� 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 travels 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 layout diagram is shown in Section 8 -
Maintenance�
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, this
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�
Refer to Section 8 - Maintenance for important battery
maintenance information�
Battery Disconnect Switch
The battery disconnect switch is labeled “Battery
Power,” and is used to separate the batteries from the
12-volt distribution panel�
The battery disconnect switch has a green backlight
when the switch is turned ON, and the batteries’
voltage is within normal operating range� When the
battery voltage drops to low, the green light will blink
for 5 minutes, indicating the batteries must be charged�
If the batteries do not begin to receive a charge, the
disconnect switch will shut off to protect the batteries
from damage�
When the trailer is plugged into an external AC power
source the 12-volt distribution panel will receive power
from the converter and the batteries will be charged
through the converter charging system regardless of if
the battery switch is in the ON/OFF position�
If the trailer is NOT plugged into an external AC power
source and the switch is turned to OFF the batteries
are disconnected and the 12-volt fuse panel will not
receive power from the converter� The converter will
not charge the batteries when no shoreline power is
present� The OFF position is intended for storage of
the trailer or when power conservation is desired�
The charge in the 12-volt batteries can be replenished,
depending on the tow vehicle, from the tow vehicle
alternator through the 7-way cord. This charge will flow
to the batteries regardless of the battery disconnect
switch position� Likewise, if ON or OFF, the solar panel
will still charge the batteries�
