OPERATION
The major portion of electrical power in your Airstream is 12-volt. The 12-volt
current powers the fans, furnaces, 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 batteries are accessible in the battery box on the A-frame of your trailer.
Power from the batteries goes to a set of four Type 2 thermal breakers located
under the front bed and riveted to the inside skin front plate. The breakers are
ties 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 brown decorative door on the front of the
converter under the dinette to access the panel and its fuses. A 12-volt layout
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 disconnect switch is used to separate the batteries from the 12-volt distri-
bution panel and converter charging system.
When the switch is turned
“use”
(on) and the trailer is plugged into a 110-volt
shoreline, the 12-volt distribution panel will receive power from the converter
and the batteries will be charged through the converter charging system.
When the switch is turned to
“store”
(off) and the trailer is plugged into a
110-volt shoreline, the 12-volt distribution panel will still receive power from the
converter, but the batteries are disconnected from the system. The batteries
will not be drained with the switch in the store position. The converter will not
charge the batteries with the switch in this position.
The charge in the 12-volt batteries is replenished when towing from the tow
vehicle alternator through the 7-way cord. This charge will go to the batteries
no matter which position the Battery Disconnect Switch is in.
