12-Volt Operation; Power Center; Auxiliary Fuse Locations - Airstream TOMMY BAHAMA 2020 Owner's Manual

Interior
Power is then routed from the battery disconnect
switch to the 12-volt distribution panel, located inside
the rear center lounge door, 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 qualified
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 find 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�
The generator starts from the house battery� If the
house battery becomes depleted, the chassis engine
can be started to charge it� It should only take a few
minutes before the generator will start�
The engine battery and house battery are isolated from
each other by a battery separation system, preventing
the two systems from drawing down simultaneously�
They will connect through the system if charging from
the engine, generator, or inverter/charger is detected�

Power Center

All Tommy Bahama models have the Power Center
installed at the base of the drivers side ottoman� Open
the decorative door for access to 12-
120-volt breakers�
The Power Center is a completely self-contained 120-
volt power distribution and energy management system
intended to be used in recreational vehicles� It is
housed in a sheet metal enclosure with removable front
panel� It provides circuit protection for all the 120-VAC
loads in the touring coach and works with the Energy
Management System to minimize the over-loading and
tripping of circuit breakers�
Refer to Section 9 - Maintenance for important battery
maintenance information�
The power center is a centralized power switching,
fusing, and distribution center. The potential
of lethal electrical shock is present in this box.
Inadvertent shorts at this box could result in
damage and/or injury. All servicing of this box
should be done by a qualified Service Technician.

Auxiliary Fuse Locations

In addition to the 12-volt fuses and breakers described
in this section, some components have additional
fuse protection as supplied or required by their
manufacturer� These locations are:
1� LP detector: 2-amp fuse behind detector
2� Monitor panel battery voltage display: under the
roadside ottoman� (1 amp)
3� Inverter: 150-amp in-line fuse under the roadside
ottoman�
4� Rear view camera: 1�5-watt in-line fuse under
