The battery switch controls the delivery of DC power
from the batteries to the engine and all equipment,
lights and accessories using DC power. The battery
switch is located on the main DC breaker panel on
the cockpit fl oor storage aft bulkhead.
NOTE: For safety and convenience the following
items are not shut off by the battery switches: bilge
pumps, sump pumps, stereo memory, systems
monitor and battery charger inputs. These items
need constant power to perform their task. This
allows the bilge pump to operate any time excess
fl uid accumulates in the bilge, which can occur
when the boat is docked and unattended. The
entire remaining DC system is turned off with the

battery switch.

GNITION
All electrical components in the engine compartment
must be ignition-protected to avoid the possibility of
creating sparks in a gasoline environment.
GASOLINE VAPORS CAN EXPLODE
Use ONLY Marine-rated parts to replace such items as
starters, distributors, alternators, generators, etc.
Do not use automotive parts for these components
or any jumper cables because they are not ignition-
protected and could cause a fi re or explosion.
Protective terminal covers, such as rubber boots
on electrical connections, must be in place when
engine is operating or when working in the engine
compartment.
Jumper cables are not ignition-protected. DO NOT
USE jumper cables in the engine compartment. The
engine compartment may accumulate dangerous
explosive gasoline fumes/vapors and hydrogen gas
from batteries being charged. A spark produced
when connecting a jumper cable can cause an
explosion.
