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
result.
“ON” - Turning the switch to position “ON” will use the
engine battery to power the 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 the two batteries,
but not allow the operator to drain down the 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 engine and 12 volt engine related equipment. The
isolator will allow the alternator to charge all batteries,
but the boat systems (including the engine) will oper-
ate off of the ships systems battery.
“PARALLEL” - With the battery selector switch in the
“PARALLEL” position, the engine and ships systems
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.
C. Battery Charger
The battery charger is standard equipment and is lo-
cated on the port side of the engine compartment. The
batteries will be charged by the battery charger when
the boat is connected 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.

VOLTMETER
On the 248/268 Vista models, one voltmeter is installed
in the dash panel to monitor the condition of the engine
batteries. When the voltage is checked during engine
or battery charger operation, the voltage of the respec-
tive battery will be indicated on the respective voltmeter.
It is common to have a 14 volt reading when the engines
are running. Additional information on voltmeters may
be found in the Engine Owner's manual.

12 VOLT ELECTRICAL EQUIPMENT
A. Helm Equipment
Ignitions are protected by circuit breakers on all Vistas.
Equipment on the helm is protected by the helm
fuseblock.
NOTICE
On the 248 and 268 Vista, a separate SYS-
TEMS breaker on the battery switch can be used
to shut down all DC equipment (except bilge
pump) on the cabin panel.
To assist you, we have listed below descriptions of indi-
vidual switches and their uses:
To prevent electrical problems, use only replace-
ment fuses or breakers that are of equal rating
to the originals.
Accessories - Accessory equipment that is customer or
dealer installed. These circuits are wired to a fuse in
the 248/268. For additional information on adding ac-
cessories, refer to Section H-4B.
Aft Bilge Pump - The BILGE PUMP switch is used to
manually activate the bilge pump in the engine compart-
ment. The bilge pump is used to remove water from the
bilge (bottom of the hull) area of the boat by pumping
that water overboard. The aft bilge pump is equipped
with an automatic bilge switch and will operate when-
ever bilge water rises to a level that will cause the float to
move upward.
This automatic bilge pump is active even if the battery
selector switch is in the OFF position or if no battery
selector switch is installed. The automatic bilge pump
circuitry is connected directly to the batteries. When leav-
