The battery disconnect feature should be used to disconnect the motorhome from house bat-
tery power during periods of storage or during maintenance.
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.
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 oat 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.
The combination carbon monoxide/propane alarm requires
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 "ON" position or when the ignition key is rotated to
the "ON" position.
Automatic Transfer Switch (ATS)
Your motorhome is equipped with an Automatic Transfer Switch. The ATS is microproces-
sor controlled and will automatically detect which power source is being used (generator
or shore power) and allow power from that connection only. You will not have to plug and
unplug power to the coach if you decide to run the generator.
If you plug into shore power, the ATS will pass power to the motorhome. If the generator
is started, it will override the shore power input (called generator dominant) and supply the
RV with electrical power from the generator. When the generator is shut down, shore power
is restored.
There may be a slight icker of the lights when the ATS changes over from one to the other,
but there is no real interruption of power.
The ATS will disconnect from shore power completely if the power coming in is not high
enough quality (i.e. either low/high voltage, or low/high frequency).
When the generator is operating, it powers the inverter/charger which in turn functions as a
multi-stage battery charger to charge the house auxiliary and chassis batteries.
