Electrical Systems - Four winns Vista 328 Owner's Manual

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 triple battery
system along with dockside power (including battery
charger) is standard on the 298/328 Vista® models. Bat-
teries are located in the engine compartment.
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 - TRIPLE BATTERY SYSTEM
Two battery selector switches are installed on dual en-
gine, triple battery installations. This allows DC power to
be used from any of the three batteries. Refer to the
schematics in the back of the manual.
A. Installation
1. Connect each of the red (positive) battery cables lead-
ing from the battery selector switch to the positive
(+) terminal on each of the three batteries. Refer to
Figure H1.
NOTICE

B. Operation
Power to the engines and all 12 volt electrical equipment
is controlled at the battery selector panel. On the 298
and 328 Vista® models, separate breakers are provided
on the battery selector switch panel to protect the en-
gine, windlass, forward and aft bilge pump, battery
charger, and ship systems.
Battery Selector Switch
The battery selector switch positions for the 298/328
Vista® 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 automatic bilge pumps. Always turn the
battery selector switch to the “OFF” position when the
boat is unattended for an extended period.
