Section 6: Electrical System
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 motorhome 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 bat-
tery 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 motorhome.
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 motorhome may be equipped with a Battery Isolation Manager that monitors the bat-
tery 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 overbur-
dened, 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 con-
sole) 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 motorhome if the chassis
battery charge is low.
The auxiliary start switch can momentarily connect both the house and
chassis batteries should the chassis battery become discharged.
To operate, depress either the “Aux. Start” switch (located on the
front driver’s dash) or the Battery Boost switch on the driver console
and hold it down. While the “Aux. Start” switch or Battery Boost
switch is depressed use the ignition key to start the chassis engine.
Release the “Aux. Start” switch (or Battery Boost switch) after the
engine has started.
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.
