Electrical System
CAUTION
Anodes deteriorate before the other metals,
thereby protecting the underwater metals from
galvanic corrosion or stray electrical current.
Since the anodes are sacricial, it is important to
monitor them and replace them when they have
deteriorated to 50 - 75% of their original size.
6.7 Electrical System Maintenance
DC Electrical System Maintenance
At least once a year, spray all exposed electrical
components behind the helm, in the transom area
and in the plugs with a protector. Exterior light
xture bulbs should be removed and the metal
contact areas coated with a non-water soluble lu-
bricant like Teon or Silicone grease. The sockets
should be sprayed with a protector. Care must
be taken not to get any oil or grease on the glass
portion of the bulbs as this will cause the bulb to
overheat and burn out.
WHEN REPLACING LIGHT BULBS IN MARINE LIGHT FIXTURES,
ALWAYS USE A BULB WITH THE SAME RATING AS THE
ORIGINAL. USING A DIFFERENT BULB COULD CAUSE THE
FIXTURE TO OVERHEAT AND MELT OR SHORT CIRCUIT.
Check all below deck wiring to be sure it is prop-
erly supported, that the insulation is sound and
that there are no loose or corroded terminals.
Corroded terminals should be thoroughly cleaned
with sandpaper or replaced, tightened securely
and sprayed with a metal and electrical protector.
Inspect all engine wiring.
Your boat is equipped with batteries that were
supplied by your Everglades dealer. Some bat-
teries are sealed, maintenance free batteries that
do not require inspection or service. However, if
your boat is equipped with standard wet cell type
batteries that are not maintenance free, they will
require the following inspection and service.
Check the electrolyte level in the batteries regu-
larly and add distilled water as necessary. If the
batteries are frequently charged by an automatic
battery charger, the electrolyte level will have to
be checked more often. The correct uid level in
the cells is usually approximately 1/4 to 1/2 inch
above the plates. If uid is needed, ll to the
proper level with distilled water. Do not over ll
and only use distilled water!
Keep all battery tops clean and dry. Dirt and water
can conduct electricity from one post to the other
causing the battery to discharge.
The battery posts should be kept free of corrosion.
Remove the cables and clean the posts and cable
clamps with a battery post cleaner or sandpaper
as required. Coating the battery posts and cable
clamps with Teon or Silicone grease will protect
them and reduce corrosion. Battery cables, both
hot and ground, must be replaced when they show
signs of corrosion or fraying. Deteriorated cables
cause a considerable voltage loss when high cur-
rents are drawn, as for starting the engine.
NEVER USE AN OPEN FLAME IN THE BATTERY STORAGE AREA.
AVOID STRIKING SPARKS NEAR THE BATTERY. A BATTERY
CAN EXPLODE IF A FLAME OR SPARK IGNITES THE HYDROGEN
GAS THE BATTERY EMITS WHILE BEING CHARGED.
CORROSION ALLOWED TO BUILD ON THE ELECTRICAL
CONNECTORS CAN CAUSE A POOR CONNECTION RESULTING
IN SHORTS OR POOR GROUND CONNECTIONS. ELECTRICAL
CONNECTORS SHOULD BE CHECKED AT LEAST ANNUALLY
AND CLEANED AS REQUIRED. DO NOT ALLOW CORROSION
TO BUILD ON CONNECTIONS.
THE ELECTRICAL SYSTEM ALWAYS SHOULD BE
DISCONNECTED FROM THE POWER SOURCE BEFORE
INSPECTING OR SERVICING THE SYSTEM. NEVER SERVICE
ANY COMPONENT OF AN ELECTRICAL SYSTEM WHILE IT IS
ENERGIZED.
