Charging Your Battery
NOTE: A marine (boat) boat battery must be removed
and charged on shore. To charge it on board requires
equipment specially designed for marine use.
Charging your battery in the vehicle:
1. Arrange the power cord and charging cords care-
fully in order to avoid damage that could be
caused by the hood, door, or moving engine parts.
2. Keep hands, hair, clothing and jewelry clear of the
fan blades, belts, pulleys, and other parts that can
cause injury.
3. Check the polarity of the battery posts using the
identification marks on the battery case: POSI-
TIVE (POS,P, +) and NEGATIVE (NEG,N, –).
4. Identify which post of the battery is grounded 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. Then connect the black
(NEGATIVE) clamp to a heavy metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines, or
sheet metal parts.
NEGATIVE GROUNDED SYSTEM
To charge a positive grounded post system:
Connect the black (NEGATIVE) battery charger
clamp to the NEGATIVE (NEG,N,–) ungrounded
post of the battery. Then connect the red (POSI-
TIVE) 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 face
away from the battery while making connections.
6. Twist or rock clamps back and forth to make a
solid connection. This will help make better
contact and help keep them from slipping off and
causing sparks.
7. Make sure the power is set to the OFF position.
Then, plug the power cord into a 3-prong AC wall
outlet.
8. Push the switch located on the front panel to
CHARGE/TEST.
9. Press the VOLT/AMP SELECTOR to the desired
charge position. (See “CHARGE RATE” chart on
page 12 for correct settings.) Charging starts.
10. Press the TIMER to the desired charge time, from
5–135 minutes. If more than 135 minutes of
charging time is needed the HOLD position can be
used. When using the HOLD feature the battery
being charged must be monitored closely to avoid
over charging.
11. When the battery is fully charged, push the switch
located on the front panel to OFF. Unplug the
charger power cord from the wall outlet.
12. Facing away from the battery, remove the charger
clamps in this order: (1) from the vehicle chassis
or engine block (2) from the battery post or
terminal.
13. Clean and store the battery charger in a dry
location.
