SAFETY PARTSTROUBLESHOOTINGOPERATION MAINTENANCE
• For deep cycle batteries, you may
wish to allow the battery another one
or two hours of charging after the LED
glows to obtain a maximum charge.
• When using the AUTOMATIC charge
rates, the LED will cycle on and off
indicating the charger is maintaining
the battery’s state-of-charge.
Charging your battery inside
the vehicle:
1. Arrange the power cord and charg-
ing leads carefully to avoid damage
that could be caused by the hood,
door, or moving engine parts.
2. Keep clear of fan blades, belts,
pulleys, and other parts that can
cause injury.
3. Check the polarity of the battery
posts as indicated on the battery
case: POSITIVE (POS, P, or +)
and NEGATIVE (NEG. N or -).
NOTE: The positive post on top-
post battery is usually larger
than the negative post.
4. Identify which battery post is
ground or connected to the chassis.
THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS
GROUNDED.
5. To charge a negative grounded
post system: Connect the red
(POSITIVE) battery charger clamp
to the ungrounded POSITIVE
(POS, P, +) post of the battery.
Rock or twist the clamps back
and forth to make a solid connection.
Then connect the black (NEGATIVE)
clamp to a heavy, unpainted metal
part of the chassis or engine block,
away from the battery. DO NOT
connect clamp to carburetor, fuel
lines or sheet metal parts. (See
Figure A.)
To charge a positive grounded
post system: Connect the black
(NEGATIVE) battery charger clamp
to the ungrounded NEGATIVE
(NEG, N, -) post of the battery. Then

CHARGING YOUR BATTERY
connect the red (POSITIVE) clamp
to a heavy, unpainted metal part of
the chassis or engine block, away
from the battery. DO NOT connect
clamp to carburetor, fuel lines, or
sheet metal parts. IMPORTANT:
Wear safety glasses and turn face
away from the battery when making
connections.
6. For automatic charging, select
AUTOMATIC DEEP CYCLE or
AUTOMATIC REGULAR as a
charge type, then select a charge
rate. The charger will stop charging
when the battery is fully charged.
7. For manual charging, select
MANUAL as a charge type then
select a charge rate. The charger
will not stop charging when the
battery is fully charged—you must
monitor and unplug charger when
battery is fully charged. Avoid over
charging, monitor the AMMETER
frequently when in the MANUAL mode.
8. Next plug the power cord into an
AC outlet.
9. When the battery is fully charged, in
the MANUAL mode, the AMMETER
pointer will fall to about half the charge
rate selected. For specific positions,
refer to the “Ammeter” section in
“Using Your Battery Charger” on
page 6.
10. When the battery is fully charged,
unplug the charger power cord
before attempting to disconnect
charger clamps.
