GENERAL

All.electrical.equipment.on.the.Four.Winns.348.Vista
models.operates.on.12.volts.DC.or.120.volts.(220.
volts.on.50.Hertz.models).AC.electrical.power..The.
348.Vista .is.equipped.with.a.triple.battery.system.

Fire or Explosion Hazard!
Electrical system parts are designed by and
manufactured to comply with the U.S. Coast
Guard requirements to minimize risks of fire
or explosion. Never substitute automotive
parts for marine parts. Automotive parts do
not provide the necessary ignition spark
protection.
.
DO NOT tamper with any electrical connection,
panel or harness, or attempt installation of any
electrical equipment unless thoroughly familiar
with the systems and experienced in making
such installations.
Circuit.breakers.are.installed.on.the.battery.switch..
to.protect.various.system.components..The.SHIP.
SYSTEMS.breaker.supplies.power.to.all.DC.electrical.
components.except.the.aft.and.forward.bilge.pumps,.
ignition,.and.instrumentation..Additional.breakers.are.
located.in.the.cabin.circuit.breaker.panel..The.circuit.
breakers.and.fuses.are.labeled.for.amperage.and.use.. .
A.helm.circuit.breaker.panel.(if.applicable),.may.also.
be.located.under.the.driver's.seat..These.circuit.
breakers.provide.additional.protection.for.certain.
components which are identified on the panel itself.

Battery Selector Switch - Dual
The.battery.selector.switch.positions.for.the.dual.
battery.selector.switch.is.as.follows:
"OFF" - With the battery selector switches in the "OFF"
position and the "SHIPS SYSTEMS" circuit breaker in
the "OFF" position, all 12 volt power to the boat is shut
off.except.to.the.fore.and.aft.automatic.bilge.pumps,.
stereo,.and.windlass..Always.turn.the.battery.selector.
switches and the SHIPS SYSTEMS" circuit breaker
switch to the "OFF" position when the boat is unattend-
ed.for.an.extended.period.
