Battery Disconnect Switches

Manual Disconnect Switch

The manual disconnect switch, located at the base of
the drivers side rear jumper seat behind the decorative
access door, is used to turn off power from the battery
to the 12-volt distribution panel� Push knob in before
manually rotating it to the ON/OFF position�
The manual disconnect switch can be used to
completely disable the main disconnect switch by
over rotating the switch in the ON/OFF positions till
a click is heard� The disable OFF feature is useful
for long term storage of the vehicle where the main
disconnect switch could be turned on and the batteries
accidentally drained� Likewise, the Disable ON feature
is useful while camping when the main disconnect
switch could be turned off cutting power to appliances�
The holding tank heat pads, rear lounge motor, solar
panel, and generator are not connected to the 12-volt
distribution panel and are wired direct in through the
thermal breakers� The main disconnect will not disable
these systems�

Multiplex System Disconnect Switch

The battery disconnect switch located on the multiplex
panel at the entry door is used to separate the 12-volt
distribution panel from the converter charging system�
When connected to an external AC power source, the
12-volt distribution panel will receive power from the
converter and the touring coach will function normally�
The batteries will be charged through the converter
charging system regardless of if the battery disconnect
switch is in the ON/OFF position�
2019 Interstate
If the touring coach is NOT plugged into an external
AC power source and the switch is turned to OFF the
batteries are disconnected and the 12-volt distribution
panel will not receive power from the converter� The
converter will not charge the batteries with the switch
in the OFF position with no shoreline power present�
The OFF position is intended for storage of the touring
coach or when power conservation is desired�
The solar panels will charge the batteries regardless of
the battery disconnect switch position� Likewise, if ON
or OFF, the generator will charge the batteries�
NOTE
As a safety precaution, the electric gas shut-off
solenoid closes automatically when 12-volt power
is disconnected, cutting gas to appliances. It will
reopen when power is restored.

Battery Separator

The Battery Separator is located at the base of the
drivers side rear jumper seat, and is accessed by
opening the decorative door� It is designed as a
solenoid priority system to protect the chassis charging
system from excessive loading, while allowing house
batteries to be maintained by the Sprinter charging
system�

Protecting the Charging System

The Battery Separator monitors the battery system
to determine if the batteries are being charged� The
charging can be accomplished through the inverter/
charger or the engine charging system� When the
engine battery or house batteries are charging, the
Battery Separator will engage, joining the two battery
banks� If charging ceases and voltage decreases in
either bank, the Battery Separator will disconnect the
two banks from each other, protecting the banks from
being discharged simultaneously�
NOTE
In the event the engine battery is depleted, Sprinter
recommends using a trickle charge only when
charging the battery. When jumping the engine
battery, do not use a power boost. Read and
follow battery charging procedures in the Sprinter
Owner's manual.
