BATTERY CONTROL CENTER

The Intellitec Battery Control Center is a centralized power switching, fusing, and distribution center.
Power from both the chassis and the coach batteries are feed into the control center box. All servicing
with-in this box should be done only by a qualified Service Technician. Page H-3 has a drawing of the
12-volt chassis wiring system used in your motor home.
Your motorhome is equipped with three batteries. One battery will be for the engine and the other two
batteries (coach) for the interior 12-volt circuits. All batteries are located under the front hood.
The Engine battery is used for starting the engine and operating the headlights, taillights, running lights,
instrument panel lighting, automotive air conditioning and other accessories. The alternator charges all the
batteries while the engine is running. The converter charges all the batteries when the unit is plugged into
shoreline.
The Coach batteries are used for interior lighting; exhaust fans, generator, water pump, central control
panel, entertainment center, optional 12-volt convenience outlets, and the refrigerator when it is switched to
12-volt power. The Intellitec Battery Control Center manual is also in your packet. It has trouble-shooting
and wiring information.
The Intellitec Primary Battery Control Center is located in the driver's side front exterior lower
compartment along with the interior 12-volt fuse panel. 12-volt power is distributed to each of the 12-volt
interior circuits of the motorhome from this fuse panel.
The Battery Disconnect switches on the panel just inside the main door acts as master switches. When the
coach switch is turned to use it opens the circuit between the coach batteries and the twelve-volt
distribution panel in the primary Battery Control Center. The chassis switch disconnects the chassis battery
from the chassis systems except for a few items such as ignition. The coach and chassis batteries are
charged by the converter whether the battery disconnect switches are in the use or store position. The
generator also charges all batteries when it is running, through the 120-volt city power system that powers
the converter.
NOTE: The chassis disconnect switch will not operate with the ignition key on.
The disconnect switches are not intended for everyday use. But if you're going to be away from your coach
for more than 3 or 4 days and it's not plugged into 110-volt current just flip the switches off on the way out
and you're assured of fresh batteries when you return.
The converter is located in the roadside front exterior compartment in the 30 FT. and 33 FT. Models.
Remove the front inside panel for access. It is under the front dinette seat in the 26 FT. Model, remove the
seat top for access.
The hydraulic pump for the leveling jacks is located under the front hood.
There are two sets of fuses controlling circuits of Airstream installed equipment in the roadside front
exterior compartment, see page H-4. The main interior circuits are fused in the 12-volt distribution panel in
and beside the Battery Control Center. The brightly colored fuses pull straight out from the face of the
panel. Replacement fuses are available at automotive stores and most service stations. There are diagrams
on the lids of both fuse panels.
Another fuse panel for the chassis fuses is located to the left of the steering column. The functions of these
fuses are marked directly on the face of the fuse block. See your Chassis Drivers Manual for further
information on chassis items. A diagram is in this section shows where Airstream picks up power for
automotive accessories. The diagrams for these fuse panels are shown later in this section.
