Refer to your Chassis Guide for information pertaining to the chassis batteries.
12-Volt Battery Disconnect
The 12-volt battery disconnect switch is typically located near
the entrance door. This momentary switch controls a solenoid
which connects or disconnects the house batteries. The switch
lights up red when turned on.
When engaged the battery disconnect solenoid supplies battery
power to all accessories connected to the house 12-volt fuse
panel. The solenoid must be engaged for the 12-volt house
electrical system to operate.
The battery disconnect feature should be used to disconnect the motor home from house
battery power during periods of storage or during maintenance.
If the Main Power switch is turned OFF, the power entrance door steps will still function
when the door is opened.
Depending on your model, your motor home will be equipped with either a Battery Isolator
Solenoid or a Battery Isolation Manager.
Battery Isolator Solenoid (If So Equipped)
The isolator solenoid breaks the connection between the house batteries and the chassis
battery when the ignition key is in the “OFF” position.
Breaking this connection prevents discharge of the chassis battery (used to start the engine)
when using 12-volt devices in the house section of your motor home.
When the engine is running the isolator solenoid engages allowing the house batteries to be
charged by the vehicle alternator.
Battery Isolation Manager (If So Equipped)
Your motor home may be equipped with a Battery Isolation Manager that monitors the
battery voltage of both the chassis and house batteries over long periods of time. If it
senses a charging voltage it connects the two batteries together. If the charge system is
overburdened, it isolates both batteries. When batteries have reached a float charge state for
(1) hour, the batteries are isolated to prevent overcharging. It will reconnect if either battery
drops to approximately 80% charge and the other is being charged. If batteries are not being
charged they will be isolated to prevent an electrical draw in one system from depleting the
other battery.
Auxiliary Start System (If So Equipped)
Depending on your model; the Battery Boost switch (on the driver console) or the Auxiliary
Start button (under the steering wheel on the lower dash) engages this solenoid and joins the
house battery with the chassis battery to provide a “boost” to help start the motor home if the
NOTE: The combination carbon monoxide/propane alarm must be
connected to a constant 12-volt power source. The carbon monoxide/
propane alarm remains operational when the battery disconnect
solenoid switch, or “main power switch,” is in the “OFF” position.
