Turn the FRESH WATER switch “OFF” when the
water tank becomes empty or when water will not be
required for an extended period or when connected
to shore water while at dockside. A tank monitoring
system is optional to check water level. Refer to
Section J-1 and J-2 in this manual for additional
information.
Stereo - The stereo has a separate switch on the unit
and is protected by a circuit breaker labeled STEREO
on the battery switch panel. A fuse located in the helm
fuse block helps to protect the circuitry.
Sump Pump - A sump pump is used to discharge
water from the shower and sink drains overboard.
The sump pump has a float switch which will activate
the pump when the water level rises to a certain level
in the sump. The sump pump is connected directly to
the battery and is protected by a circuit breaker
located on the battery switch panel for the bilge.
If the boat is equipped with a grey water system,
the water from the shower and sinks is pumped into
a holding tank instead of overboard.

SHUTDOWN PROCEDURES
When leaving your boat unattended for an extended
period of time it is advisable to shutdown the electrical
system to reduce battery drainage and/or possible
electrical draw.
To shutdown:
1. Turn the battery switch(s) to the “OFF” position.
2. If your battery switch has a SHIP SYSTEMS circuit
breaker switch, move the switch to the “OFF”
position.
H - 7 120 (220) VOLT ELECTRICAL SYSTEM
The boat is equipped with 30 amp, 120 volt, 60 Hertz
(or 15 amp, 220 volt, 50 Hertz) AC electrical wiring.
When the boat is connected to a shore power outlet,
the AC system supplies electrical power to the
following items: battery charger, galley refrigerator,
water heater, range, microwave, outlets, and air condi-
tioning (if applicable). The dockside system uses
three-wire, color-coded circuitry. The black or hot wire
is the ungrounded current carrying conductor. The
white or neutral wire is the grounded current carrying
conductor. The green wire, referred to as the “equip-
ment ground,” is a grounded conductor, and under
normal conditions is not a current carrying wire.
The neutral wires are connected together at a buss
bar. The equipment grounds are similarly connected
together at another buss bar. Each hot wire is con-
nected to, and protected by, a circuit breaker in the
distribution box located in the AC cabin panel identi-
fied “120V 60Hz”.
The SHORE POWER dockside inlet is located on the
port side of the deck. The standard dockside system
has a main circuit breaker which protects the overall
distribution network. The 258 and 278 Vista
®
models
have SHORE POWER (main) circuit breakers on the
120V AC cabin panel. In order to have AC system
operation, the SHORE POWER breakers must be
turned “ON” and the boat must be connected to shore
power or have the generator (if applicable) running
and generator breakers “ON”.
The SHORE POWER circuit breakers protects both
the hot and neutral input leads. This breaker is
sensitive. The resulting power surge which occurs
when connecting the shore power cord may cause the
SHORE POWER breakers to trip. To avoid this power
spike, turn off the SHORE POWER breakers before
plugging in the shore power cord. Securely connect
the power inlet of the boat and the shore power
receptacle. Once the shore power is securely con-
nected, turn the SHORE POWER breakers back on.
If the connection is broken and later re-secured, the
circuit breaker may trip. Connections must be secure
for uninterrupted dockside service.
The AC voltage for the generator, or shore power AC
systems may be monitored with the AC voltmeter in
the AC panel.
H - 8 DOCKSIDE OPERATION
If any abnormalities appear during dockside
operation, DISCONNECT the system immedi-
ately to prevent electric shock hazards! Have
the boat’s electrical system and the shoreside
receptacles checked as soon as possible.
