6.8 Electrical System Maintenance
General System Maintenance
At least once a year, spray all exposed electrical
components behind the helm, in the stern bilge
area and in the plugs with a protector. Remov-
able light fixture bulbs should be removed and
the metal contact areas coated with a non-water
soluble lubricant like Teflon 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.
Notice:
Most LED light fixtures are sealed and not
serviceable.
CAUTION
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 Crevalle dealer. Some batter-
ies 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 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 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 on all batteries 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 Teflon or
Silicone grease will protect them and reduce cor-
rosion. 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.
WARNING
NEVER USE AN OPEN FLAME IN THE BATTERY STORAGE
AREA. AVOID STRIKING SPARKS NEAR THE BATTERY. A BAT-
TERY CAN EXPLODE IF A FLAME OR SPARK IGNITES THE
HYDROGEN GAS THE BATTERY EMITS WHILE BEING
CHARGED.
WARNING
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.
