Typical converter: model, features, and
installation location varies, depending on
motorhome model and floor plan.
Master Battery Disconnect Switches
When traveling, the Master Battery Disconnect Switch
must be turned ON to operate the dash radio and
backup camera system (if equipped).

NOTICE
Master Battery Disconnect Switch
The 12 volts DC Master
Battery Disconnect
Switch is used to discon-
nect the motorhome’s
12 volt DC electrical
system from auxiliary or
house battery. It is gen-
erally a good practice
to turn ON the Master
Battery Disconnect
Switch when entering
the motorhome and
keep it on during travel.
This will allow all 12
volt electrical systems
to remain operational
and allows the chassis
alternator to charge the
auxiliary battery(ies).
Doing so also provides
power to the dash radio
and vision system.
If not connected to shore power, turn the Master Battery
Disconnect Switch OFF when leaving the motorhome for
periods of more than 1 hour. Doing so will help prevent
excessive battery drain.
When connected to shore power or generator power, the
Master Battery Disconnect Switch seems to be is ineffective,
however, this is normal. 12 volt power is being supplied by
shore power or the generator through the converter.
Automatic Transfer Switch
The Automatic Transfer Switch is an electronically
controlled relay that senses the presence of 120 volts AC
incoming power; either from shore power or from the
on-board generator. It automatically switches between
these two incoming power sources, connecting the active
incoming power source to the Power Load Center, through-
which, powering the motorhome’s electrical system.
When 120 volts AC is not present, the Automatic Transfer
Switch connects the auxiliary battery to the house 12 volt
system. If an inverter is installed, limited 120 volts AC is
available for a restricted number of circuits and appliances.
THE AUTOMATIC TRANSFER SWITCH
OPERATES UNDER THESE CONDITIONS:
• When shore power is sensed, it connects the external
AC power source to the Power Load Center.
• If there is a shore power outage and the generator is
started, either manually or by the Automatic Generator
Start System (see Section 10, AGS), incoming power is
switched from the shore power source to the generator
after a 20-45 second delay.
• If shore power returns while the generator power is
present, the system remains on generated power until
the generator is turned off. With the generator off,
electrical power for the motorhome is switched to the
shore power source.
• The generator overrides shore power.
NOTE: The transfer switch supplied with your motor-
home is rated for either 30 amp or 50 amp service,
depending on the electrical system configuration of
your motorhome.
Converter
The power con-
verter turns 120
volts AC power to
usable 12 volts DC
power when the
shore line power
cord is connected to
an external power
source. The convert-
er has a built-in
protective thermal
breaker that will
shut it down should
overheating occur.
Overheating can be caused by operating the converter
above its maximum power output for an extended period
of time, or by an obstruction to its ventilation air flow.
Inspection and Maintenance
If the power converter is not working check the fuse(s)
located on the outer case. There are no customer service-
able parts inside the converter case and the manufacturer’s
warranty will be voided if the case has been opened. If you
have further concerns please contact your selling dealer.
