NOTICE
DO NOT turn a battery selector switch to the
"OFF" position while an engine is running. Alter-
nator and wiring damage could result.
NOTICE
Start one engine, and then the other. Attempting
to start both engines by turning both ignition keys
simultaneously may damage electrical compo-
nents and is not recommended.
NOTICE
The 278 Vista may include the installation of an
isolator as an option. This is a recent change. If
installed, both batteries will be charged at all times.
Monitor the batteries' condition regularly with the Voltme-
ter. See Section E-5 and B-8e in this manual for addi-
tional information.
C. Battery Charger
The batteries in a dual battery system may be charged by
a battery charger/converter when the boat is connected to
dockside power. Refer to Table II above for location.
Additional information on the battery charger can be found
in Section E-8b 120 Volt AC Equipment in this manual
and refer to the manufacturer's literature included with this
manual.

VOLTMETER
A Voltmeter is installed in the dash to monitor the condi-
tion of the batteries. On the 278 Vista with dual engine
installation, two voltmeters are installed in the dash panel.
When the voltage is checked during engine or battery
charger/converter operation, the voltage of the respective
battery will be indicated on the voltmeter. It is common to
have a 14 Volt reading when the engines are running.
Additional information on voltmeters is noted in Section B-
8e and in the Engine Owners manual.

12 VOLT ELECTRICAL EQUIPMENT
A. Helm Equipment
Equipment on the helm is protected by fuses or circuit
breakers below the dash on all models. The ignition, DC
outlet, and panel switches are protected by the circuit
breaker panel located below the dash, behind the ac-
cess door on the 278 model. The 238 and 258 models
have an automotive-type fuse panel below the dash.
NOTICE
On the 278 model, a separate SYSTEMS
breaker on the battery switch can be used to
shut down all DC equipment (except bilge pump)
on the cabin panel.
Refer to the descriptions of individual switches below.
To prevent electrical problems, use only replace-
ment fuses or breakers that are of equal rating
to the originals.
Accessories - Accessory equipment such as the spot-
light and marine radio have separate controls and are
wired to the fuse or circuit breaker panel below the dash.
For additional information on adding accessories, refer
to Section E-3b.
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 whenever
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 leaving your boat unattended for an extended pe-
riod, check the charge on the battery(s) periodically. Also
check the water level in the bilge and make sure the float
switch is functional.
If the automatic bilge pump must be disabled, discon-
nect the wiring plug near the bilge pump.
