7.1.1 Batteries
DANGER
! !
Batteries contain Sulfuric Acid and can cause severe
personal injury if mishandled.
Avoid contact with eyes, skin, or clothing. In case of
contact, flush with water at least 15 minutes.
If swallowed, drink large quantities of water or Milk
of Magnesia, beaten egg, or vegetable oil and get
medical attention immediately.
WARNING
! !
Charging batteries produces gasses which can ex-
plode if ignited.
Explosion can shatter a battery.
Battery acid can cause severe personal injury such
as blindness.
Keep flame, spark, and smoking materials away from
batteries while charging. Charge in a well ventilated
area.
The DC System derives its power from two separate
battery banks.
The negative terminal of all banks are attached to the DC
Ground connection on the engine. This system, known as
the negative ground system, is the approved system for
marine DC electrical systems. The battery wiring system
has two color coded wires. The yellow wire is the ground
(negative), and the red wire is (positive).
To avoid explosions, do not use jumper cables and a
booster battery to start the engine. If batteries are dead,
then remove and recharge them ashore.
Batteries produce hydrogen and oxygen gasses when
they are being charged. These explosive gasses escape
through the vent/fill caps and may form an explosive
atmosphere around the battery if ventilation is poor. This
gas may remain around the battery for several hours after
charging. Sparks or flame can ignite the gas and cause
an explosion.
WARNING
! !
Batteries contain a large amount of potential
electrical energy!
Extreme care must taken when working with
batteries.
An improper connection to a battery can release
enough energy to cause severe personal injury or
fire.
The following precautions must be taken:
The wiring to the batteries must have proper over
current protection in the form of fuse or breakers.
Use only battery chargers that have been listed by a
testing agency, such as Underwriters Laboratories,
Inc.
Follow the wiring diagrams exactly.
To remove the battery:
Turn off all power drawing breakers and isolate bat-
tery.
Remove negative (-) cable first, then the positive (+).
When you install a battery, the battery connections must
be made properly.
Attach the positive cable to the positive (+) terminal
on the battery.
Attach the negative cable to the negative (-) terminal
on the battery.
Note: Batteries should always be removed and installed by
trained, qualified persons to avoid all damages.
7.1.2 Battery Switch
Each battery has a battery selector switch (Fig. 7.2)
located in the bunk face forward of the chart table.
The selector switches are marked as to which battery
they control. Turning the selector switch to the Off posi-
tion turns power off to the respective circuits, likewise, the
On position turns power on.
