5-10 2017 Interstate
12-Volt Operation
The only thing you have to do is make sure the house
battery does not run down� In normal usage, there is
not any problem, since you would normally be plugged
into a 120-volt shoreline at night or when camping�
When you’re plugged into shoreline power or running
the generator, with the battery disconnect turned to
“ON” the inverter/charger charges the battery and
carries much of the load�
Some nights you may not nd 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 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 Interstate 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�
