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 CIR-
CUIT.
Check all below deck wiring to be sure it is properly 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.
Check the electrolyte level in the 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 usually 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! Please note that some batteries are sealed and cannot be filled.
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 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 engine.
NEVER USE AN OPEN FLAME IN THE BATTERY STORAGE AREA. AVOID STRIK-
ING 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 insulation and corrosion in electrical connectors.
Spraying receptacles and electrical connections with an electrical contact cleaner or a metal and
electrical protector will reduce corrosion and improve electrical continuity.
Inspect all wiring for proper support, sound insulation, and tight terminals, paying particular
attention to portable appliance cords and plugs.
The entire AC circuitry, especially the shore power cord, should be seasonally tested for proper
continuity by an experienced electrician. This will detect any shorts, open wires, or ground faults.
Ground fault interrupters should be tested periodically to ensure proper operation by pressing the
test/reset buttons in the center of the face plate. The polarity indicator system also should be
inspected for proper operation.
