as only the surplus goes to charging the
battery. (Please refer to the specifications
section for more information on power
consumption.) If you are making an extended
stay or storing your Airstream, then you
should (if it is availablee) keep your trailer
hooked up to 120 volt current.
Whenever possible, use the automatic built-in
charger of the Univolt System for charging.
The charging circuit automatically controls
the current, reducing it as the battery in¬
creases in charge. At service stations, make
certain they give your battery a slow charge
because quick charges will drastically shorten
the life of the battery as will allowing
repeated complete discharges.
The Univolt is located at the rear curbside
interior next to the bathtub in rear bath
models, and is accessible through the rear
wardrobe or through the bedroom partition
under the bed, depending upon the particular
model.
In center bath models the Univolt is located
under the galley and is accessible through a
door attached to the magazine rack.
On rear bath models the 120 volt circuit
breaker panel is in the rear roadside wardrobe.
On center bath models it is located under the
bathroom lavatory top. In the event of failure
of a 120 volt circuit, check your circuit
breaker first. While you are connected to the
120 volt receptacle, the wiring is protected by
circuit breakers in the breaker panel. If a
breaker continues to trip after you have reset
it several times, your circuit may be over¬
loaded with appliances or there may be a
short in the circuit. If lessening the load does
not solve the problem consult an Airstream
Service Center or the factory.
The Univolt System and the Central Control
Panel are provided with a series of fuses (see
illustrations page 63) for the safety of you
and your unit. Trouble with the electrical
system is extremely unlikely, but if it should
occur we recommend that you contact your
nearest Certified Service Center for repairs.
We have included a trouble shooting chart to
be used in emergencies only. Details of
electric motor amperage, light bulb size, and
fuse and circuit breaker locations are shown
on the chart in the specifications section on
page 64.
When being towed, the 12 volt battery in
your Airstream is receiving a constant charge
from the car's generator or alternator through
the Seven Way Connector. The charge rate is
controlled by your automobile's voltage
regulator. It is important to keep the seven
way connector clean: one method is to use
"Spra-Kleen."
