Isolator

Power from the alternator is channeled through an isolator. This device allows the
alternator to simultaneously charge the chassis and house system, while still keeping
the two systems separate. When the isolator is used, draining the house batteries will
not affect the chassis batteries, and vice-versa. The solar isolator feeds power from the
solar panel to the main isolator. With a small amount of care, at least one battery system
will always be charged.

Boost Switch

If the chassis batteries lose their charge and become unable to start the engine, it is possible
to apply the house system to the task. A boost switch, located on the driver's console,
connects the two systems. By activating the switch, the starter can get power from the
house batteries and converter. The boost switch should only be activated for the time
that the power is needed.
NOTE: To start the engine when both the chassis and house batteries have lost their

House System

The house 12 VDC system provides the power for all 12 VDC accessories with the
exception of the engine starter, leveler pump, generator, and automotive functions.
The system includes two batteries that are designed to preserve their power, even after
repeated drains and charges, as long as the battery is properly maintained. This battery
type is known as a "deep cycle" battery. The system is routed through the fuse panel
located under the bathroom sink or in the lower galley cabinet.
