Electrical System
and sprayed with a metal and electrical protector.
Inspect all engine wiring.
Check the electrolyte level in wet cell batteries
regularly and add distilled water as necessary.
If the batteries are frequently charged by the
automatic battery charger, the electrolyte level
will have to be checked more often. The correct
fluid level in the cells is approximately 1/4 to 1/2
inch above the plates. If fluid is needed, fill to the
proper level with distilled water. Do not over fill!
Notice:
AGM and some wet cell batteries are sealed
and do not require or allow the inspection of
the electrolyte.
Keep the 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 petroleum jelly or dielectric 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 currents are drawn, as for
starting the engines.
DANGER
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.
AC Electrical System Maintenance
Periodically inspect all wiring for nicks, chafing,
brittleness, improper support, etc. Examine the
shore power cord closely for cracks in the insula-
tion and corrosion in electrical connectors. Spray-
ing receptacles and electrical connections with an
electrical contact cleaner or a metal and electrical
protector will reduce corrosion and improve elec-
trical continuity.
Inspect all wiring for proper support, sound in-
sulation and tight terminals, paying particular
attention to portable appliance cords and plugs.
The entire AC circuitry, especially the shore power
cords, should be seasonally tested for proper
continuity by an experienced electrician. This will
detect any shorts, open wires, or ground faults.
Ground fault interrupt outlets and ELCI should
be tested monthly to ensure proper operation by
pressing the test/reset buttons. The reverse po-
larity system should also be inspected and tested
periodically for proper operation.
Generator Maintenance
The engine maintenance required on the genera-
tor is similar in many ways to the main 4-stroke
outboard engines. The most important factors
to the generator’s longevity are proper ventila-
tion and maintenance of the fuel system, cooling
system, lubrication system and the AC alternator.
The seawater cooling system is equipped with
a sacrificial anode and that should be checked
whenever the generator is serviced and replaced
as necessary. Maintenance schedules and pro-
cedures are outlined in your generator owner’s
manual. They should be followed exactly.
WARNING
CORROSION ALLOWED TO BUILD ON THE ELECTRICAL
CONNECTORS CAN CAUSE A POOR CONNECTION RESULTING IN
SHORTS, GROUND FAULTS OR POOR GROUND CONNECTIONS.
ELECTRICAL CONNECTORS SHOULD BE CHECKED AT LEAST
ANNUALLY AND CLEANED AS REQUIRED. DO NOT ALLOW
CORROSION TO BUILD ON CONNECTIONS.
ELECTRIC SHOCK CAN CAUSE SEVERE INJURY OR EVEN
DEATH. THE AC AND DC ELECTRICAL SYSTEMS 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.
