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 the Battery Separator, preventing the
two systems from drawing down simultaneously� They
will connect through the Separator 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 rear jumper
seat� Open the decorative door for access to 12-
volt
fuses and 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�
WARNING
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.

Multiplex System
The Multiplex System provides advanced automation
and mobile electrical solutions for your touring coach�
Firefly is a multiplex network system designed to
combine multiple signals across a media to reduce
wires and simplify end user control� The system
combines all desired functions and controls of the
touring coach into a central location� Regional control
panels are installed to operate specific areas.
The switch panels conveniently located throughout the
touring coach allow you to turn your lighting on or off,
as well as, the ability to dim lighting to a desired level
with the touch of a button� Each button is illuminated,
when it is pressed, indicating the circuit is either ON or
OFF� The button will turn white when the circuit is OFF
and blue when it is ON�
NOTE
Buttons that are controlling circuits such as Light
Master and Panel Lights typically Do Not change
from blue to white.
