ELECTRICAL SYSTEMS

H - 1

GENERAL

All electrical equipment on the Four Winns Vista® mod-
els operates on either 12 volts DC or 120 volts (220 volts
on 50 Hertz models) AC electrical power. A quadruple (4)
battery system along with dockside power (including bat-
tery charger) is standard on the 378 Vista™. One bat-
tery is designated for the port engine, one is for the star-
board engine and two batteries are designated for the
ships systems. Batteries are located in the engine
compartment. See Figure H2.
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 pro-
tect various system components. The SHIP SYSTEMS
breaker supplies power to all DC electrical components
except the aft and forward bilge pumps, ignition, and in-
strumentation. Additional breakers are located in the
cabin circuit breaker panel. The circuit breakers and fuses
are labeled for amperage and use.
H - 2 DUAL ENGINE - QUAD BATTERY SYSTEM
Two battery selector switches are installed on the bat-
tery switch panel of a dual engine, quad battery system.
Please note that only in an emergency start situation
can DC power be drawn from any one of the batteries.
At any other time, DC power is drawn only from the
designated battery(s). The battery switch panel is lo-
cated inside the ship systems door, which is located at
the port cockpit bulkhead, near the stern. See Figure
H1. Refer to the battery switch schematic in the back
of the manual for wiring information.
