Electrical System
When in port or at anchor, the ENGINE and EMER-
GENCY PARALLEL switches should be OFF. Only
the HOUSE battery should be ON. This will keep
the engine starting battery in reserve for start-
ing the engine. If the house battery becomes
discharged the engine can be started to recharge
the house battery by turning ENGINE battery ON
and starting the engine.
The engine battery is dedicated to starting and
operating the engine. If the engine battery be-
comes discharged, the engine and house batteries
can be temporarily connected in parallel with the
EMERGENCY PARALLEL switch to provide addi-
tional starting current for the engine. To connect
the batteries in parallel to start the engine, make
sure the ENGINE battery switch in ON, then turn
the EMERGENCY PARALLEL switch to ON and start
the engine. Once the engine has started and
systems have stabilized, turn the EMERGENCY
PARALLEL switch OFF. Once the engine is running
the automatic isolator relay will direct charging
current to both batteries with the lowest battery
receiving the most charging current.
NOTICE:

control memory and stereo memory when
the batteries are connected, even if the bat-
tery switch is off.
6.3 Twin Engine Battery System
The 12 volt electrical system on the 328SS twin
engine boats is a standard marine system. Three
batteries with an ON/OFF switch for each battery
and an emergency parallel switch is standard
equipment. The batteries are located in the front
of the engine compartment. The battery switch
panel is located in a compartment on the side of
the cockpit near the transom door. The batter-
ies are charged by the engine or by the battery
charger when hooked to shore power or when the
optional generator is operating.
All 12 volt power is distributed to the 12 volt
accessories through individual circuit breakers
located in the 12 volt breaker panels. A main
helm circuit breaker, located near the battery
switches, protects the system from an overload.
Other circuit breakers, located near the battery
selector switches, protect the circuits for the bilge

interior lights, water pump, sump pump, stereo,
arch, 12 volt receptacle, cockpit refrigerator, mac-
erator and optional windlass. Other fuses or circuit
breakers in the engine compartment protect the
circuits for the optional electronic active corrosion
systems, battery charger and windlass. Most 12
volt accessories are operated directly by switches
in the helm accessory switch panels or separate
accessory switch panels.
Main breakers located on the engine protect the
ignition, engine charging systems and gauges.
Some 12 volt accessories are operated directly
by a circuit breaker in the breaker panels while
others are operated by a switch fed by the panel
breakers and/or the power management module
behind the helm. Most of the 12 volt accessories
on the deck and in the cockpit are operated by
switches in the helm switch panels.
FOR ALL 12 VOLT EQUIPMENT ADDED. DO NOT OVERLOAD
THROUGH ADDITIONAL 12 VOLT EQUIPMENT.
