Charging your battery outside the vehicle:
NOTE: A marine (boat) must be removed and charged
on shore. To charge it on board requires equipment
specially designed for marine use.
1. Remove battery from vehicle, making sure to dis-
connect grounded terminal first with all power
turned off to the vehicle.
2. Check the polarity of the battery posts as indicated
on the battery case: POSITIVE (POS,P,+) and
NEGATIVE (NEG,N,–).
NOTE: On top-post batteries, the positive battery
terminal usually has a larger diameter than the
negative one.
3. Connect the red (POSITIVE) charger clamp to the
POSITIVE post of the battery. Be sure to rock the
clamp back and forth to make a solid connection.
4. Attach at least a 6-gauge (AWG) insulated battery
cable of at least 24-inches in length to the NEGA-
TIVE battery post. This cable will provide a safer
connection because any arcing and sparking will
not occur directly over the battery. (The battery
cable is not provided with the charger but may be
purchased at most automotive accessory outlets.)
5. Take the other end of the 6-gauge (AWG) insu-
lated battery cable (at least 24-inches in length),
and, standing as far away from the battery as
possible, connect the black (NEGATIVE) charger
clamp to the free end of the cable. Be sure to rock
the clamp back and forth to make a solid connec-
tion.
IMPORTANT: Wear safety glasses and face
away from battery while you are making the final
connection.
6. Make sure the power is set to the OFF position.
Then, plug the power cord into a grounded 3-
prong AC wall outlet.
7. Push the switch located on the front panel to
CHARGE.
8. Press the TIMER to the desired charge time, from
30-135 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.
9. Press the VOLT/AMP SELECTOR to the desired
charge position. (See “CHARGE RATE” chart on
page 12 for correct settings.)
10. When the battery is fully charged, turn OFF the
timer, then push the switch located on the front
panel to OFF. Unplug the charger power cord from
the wall outlet.
11. Face away from battery and remove the charger
clamps from the NEGATIVE end of the cable first,
then from the POSITIVE post.
12. Clean and store the battery charger.
