NOTICE
Twelve volt power to the cabin panel is supplied
by the “SHIPS SYSTEMS” circuit breaker on the
battery selector panel. This must be turned on
to operate any 12 volt accessories on the cabin
panel. The bilge pumps receive power from the
ships system battery and remain on at all time
regardless of battery selector or ship systems
switch position.
NOTICE
DO NOT turn the battery selector switch to the
“OFF” position while its corresponding engine is
running. Alternator and wiring damage could re-
sult.
Port Engine Battery Switch:
“ON” - Turning the switch to position “ON” will use the
port engine battery to power the port engine and 12 volt
engine related equipment. The ships system battery
will not be used for any engine related equipment, but
will power all other 12V equipment on the boat. The
isolator will allow the alternator to fully charge all three
batteries, but not allow the operator to drain down either
engine start battery. “ON” is the recommended switch
position for normal boat operation. This position allows
maximum use of 12V equipment on the boat and leaves
a full charge in both engine batteries for starting.
“SHIP SYSTEMS” - Turning the switch to position “SHIPS
SYSTEMS” will use the ships system battery to power
the port engine and 12 volt engine related equipment.
The isolator will allow the alternator to charge all batter-
ies, but the boat systems (including the engine) will op-
erate off of the ships systems battery.
“PARALLEL” - With the battery selector switch in the
“PARALLEL” position, the port engine and ships sys-
tems batteries are connected in parallel. Both batteries
will be used by the engine and all 12 volt equipment. Both
batteries will be charged by the alternator through the
isolator.
Starboard Engine Battery Switch:
“ON” - Turning the switch to position “ON” will use the
stbd engine battery to power the stbd engine and 12 volt
engine related equipment. The ships system battery
will not be used for any engine related equipment, but
will power all other 12V equipment on the boat. The
isolator will allow the alternator to fully charge all three

batteries, but not allow the operator to drain down either
engine start battery. “ON” is the recommended switch
position for normal boat operation. This position allows
maximum use of 12V equipment on the boat and leaves
a full charge in both engine batteries for starting.
“SHIP SYSTEMS” - Turning the switch to position “SHIPS
SYSTEMS” will use the ships system battery to power
the stbd engine and 12 volt engine related equipment.
The isolator will allow the alternator to charge all batter-
ies, but the boat systems (including the engine) will
operate off of the ships systems battery.
C. Battery Charger
The battery charger is standard equipment and is located
in starboard engine compartment. The batteries will be
charged by the battery charger when the boat is con-
nected to dockside power.
Additional information on the battery charger can be found
in Section H-6B - 120 Volt AC Equipment in this manual
and refer to the manufacturer’s literature included with
the owner’s packet.
H - 3 VOLTMETER
On the 298/328 Vista®, two voltmeters are installed in
the dash panel to monitor the condition of the port and
starboard engine batteries. When the voltage is checked
during engine or battery charger operation, the voltage of
the respective battery will be indicated on the respective
voltmeter. It is common to have a 14 volt reading when
the engines are running. It should be noted that located
in the cabin panel is a voltmeter which monitors the
“SHIPS SYSTEMS”. Additional information on voltme-
ters may be found in the engine owner's manual.
H - 4 12 VOLT ELECTRICAL EQUIPMENT
A. Helm Equipment
Ignitions are protected by circuit breakers on all Vista®
models. Equipment on the helm is protected by circuit
breakers in the helm and in the cabin’s AC/DC panel.
NOTICE
On the 298 and 328 Vista® models, a separate
SYSTEMS breaker on the battery switch can be
used to shut down all DC equipment (except
bilge pump) on the cabin panel.
