USING AN EXTENSION CORD
Loosen and remove each nut from bolts
at battery terminal. One at a time, slip
the eyelets of the harness wires over the
bolt at battery terminal. Replace and
tighten nuts to secure.
The use of an extension cord is not
recommended. If you must use an
extension cord, please make sure
that you follow these guidelines:
ELECTRICAL INSTALLATION
• Make sure that the pins on charger's
power cord fit firmly into the extension
cord, and that the extension cord fits
firmly into the receptacle.
Route and secure the output away from
gas line, carburetor, or other hot, sharp
or moving parts to avoid damaging the
wire insutation. Secure the wiring to the
frame or cable using a self locking cable
tie or equivalent.
• Check that the extension cord is
properly wired and in good electrical
condition.
Make sure that the wire size is large
enough for its length and for the AC
ampere rating, as specified in the
chart below.
PLUGGING IT IN
Your charger requires a 120V receptacle
installed according to all local cedes
and ordinances.
WARNING: Electrical Shock Hazard. Be
sure that the power cord fits properly
into the outlet, If not, have a qualified
technician install a proper outlet. Never
alter the AC cord or plug provided.
Improper connection can result in
electrical shock.

It is important that you read and follow these guidelines while you are preparing to
charge your battery.
• Make sure that you have a 12 volt or
6 volt lead-acid battery. Set the
selector switch to match the voltage
rating of the battery to be charged.
• Clean the battery terminals. Be
careful to keep corrosion from getting
in or around your eyes.
• For batteries with removable cell
caps, if required, add distilled water to
each cell until the battery acid
reaches the level recommended by
the manufacturer. This will help purge
excessive gases from the cells. Be
careful not to overfill. If you have a
sealed battery without cell caps, no
action is necessary. Continue to the
next step listed below.
cell caps while charging, and recommended rates of charge.
• Wear safety glasses. See additional
"Personal Safety Precautions" on
page 4.
• Be sure that the area around the
battery is well ventilated while it is
being charged.
• If it is necessary to remove the battery
from the vehicle to charge it, always
remove the grounded terminal from
the battery first. Turn off all vehicle
accessories to avoid sparks from
occurring.
NOTE: A marine battery installed in a
boat must be removed and charged on
shore.

c) Plug AC power cord into 120 Volt, 60 Hz
receptacle.
d)The amber light indicates battery is
being charged, the green light indicates
battery is fully charged, and the red light
indicates trouble. See more detailed
exPlanation below.
• When properly connected, the amber
LED indicator should illuminate, This
indicator will stay illuminated until the
battery voltage has reached approximately 14,4 Volt and the charge current has decreased to 0.5 Amps. At
this point, the amber indicator turns
off and the green indicator turns on.
Also at this point, the internal voltage
reference of the charger will change
in order to maintain the battery voltage at 13.2 Volt. At this lower voltage,
charger current is typically a few milliamperes (mA) (1 mA = 0.001 A).
Under this condition called maintain,
most batteries can be left charging
indefinitely. If the battery is loaded
with 0.5 Amps or greater white in the
maintain condition, the charger will
change back to the normal charging
condition described above.
• Never leave the battery connected to
the charger while the charger is unplugged from the AC outlet. The
charger draws a few milliamperes
(mA) from the battery and will eventually rundown the battery.
The Red LED indicates an overload
condition. Common causes are shorting of the battery clamps, reversepolarity connection to a battery, and
charging a problem battery. An overload condition could also be caused
by charging two or more batteries in
parallel or charging a battery larger
than the size commonly used in a car
or truck. Once the charger goes into
the overload state, it will not automatically reset to the normal charge
state. One of the battery clamps must
first be disconnected from the battery
for at least 5 seconds.
