Electrical System
Electrical system maintenance is limited to care and
replacement of the battery (see below). Other electrical
components do not require regular or preventative
maintenance. Replacement or repair of these
components is covered in the Workshop Manuals.
Fuses, relays and circuit breakers are covered at Fuse
and Relay Box, page 72.
Battery
DANGER!
Risk of explosion. Batteries generate a highly volatile
gas. Keep all smoking, flames, and sparks away from
the batteries.
Also observe the following;
All batteries must be enclosed in approved marine
battery boxes, with covers. The battery and box must
be secured.
Always ventilate the area where the batteries are
stored before beginning any work.
Before working on the cables turn the battery switch to
OFF and disconnect any accessories wired directly to
the battery.
Incorrect battery cable connections can create a spark,
make sure battery cables are mounted to the correct
battery post; + to +, — to —.
A spark can also be created when connecting or
disconnecting the cables. If there are electrical loads
on the positive cable they will arc when the cable is
installed. Remove the negative cable first and install it
last to reduce arcing.
WARNING!
Risk of chemical burns. Battery electrolyte is very
corrosive. Wear eye protection when working around
batteries. Electrolyte spilled on the skin should be
immediately flushed off with water.
NOTICE! Do not disconnect the batteries if the engine
is running, electrical components may be damaged.
NOTICE! Do not use wing nuts to secure battery
cables, even if they were supplied with the battery; use
a nut and lock washer to secure the cables.
Proper maintanance and care will increase the
reliability and service life of the batteries;
•
Battery posts and cables should be free of
corrosion. If corrosion is present disconnect the
cables and clean the posts and cable ends.
