Charging Battery In/Out Of Vehicle - Schumacher DY-1420 Owner's Manual

F. OPERATING INSTRUCTIONS: CHARGING BATTERY IN VEHICLE
When charging battery in the vehicle, take care to determine the battery type and which post is grounded (connected to vehicle chas-
sis). To reduce risk of a spark near battery, follow these steps when battery is installed in vehicle. WARNING: A spark near battery
may cause battery explosion.
1. Position AC power cord and DC charging cords to reduce risk
of damage by hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys, and other parts that
can cause injury.
3. Check polarity of battery posts. Battery case will be marked
by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG,
N, -). NOTE: The positive battery post usually has a larger
diameter than the negative post.
4. Determine which post of battery is ground (connected) to
chassis.
NOTE: The negative post is normally grounded.
NEGATIVE GROUNDED POST
5A. For negative-grounded vehicle, connect POSITIVE (RED)
clip from battery charger to POSITIVE (POS, P, +) ungrounded
post of battery. Connect NEGATIVE (BLACK) clip to vehicle
chassis or engine block away from battery. Connect to a heavy
gauge metal part of the frame or engine block.
POSITIVE GROUNDED POST
5B. For positive-grounded vehicle, connect NEGATIVE (BLACK)
clip from battery charger to NEGATIVE (NEG, N, -) ungrounded
post of battery. Connect POSITIVE (RED) clip to vehicle chassis
or engine block away from battery. Connect to a heavy gauge
unpainted metal part of the frame or engine block.
G. OPERATING INSTRUCTIONS: CHARGING BATTERY OUT OF VEHICLE
When charging battery out of vehicle, take care to determine the battery type. To reduce risk of a spark near battery, follow these steps
when battery is outside vehicle. WARNING: A spark near the battery may cause battery explosion. WARNING: When removing battery
from vehicle or boat, disconnect grounded pole first. When disconnecting, make sure all accessories are off, so as not to cause an arc.
(NOTE: A marine (boat) battery must be removed and charged on shore. (To charge on board requires special equipment designed for
marine use.) WARNING: When reinstalling battery, attach the ground post first.
1. Check polarity of battery posts. Battery case will be marked
by each post: POSITIVE (POS, P, +) and NEGATIVE (NEG,
N, -). NOTE: The positive battery post usually has a larger
diameter than the negative post.
2. Attach a 24-inch long (or longer) 6-gauge (AWG) insulated
battery cable to NEGATIVE (NEG, N, -) battery post.
(The 24" lead is not supplied. You may purchase at most
automotive stores.)
The 24" lead provides a safer connection condition. Sparking
or arcing could occur when connecting the charger clip to
the lead.
3. Connect POSITIVE (RED) charger clip to POSITIVE (POS,
P, +) post of battery. Rock clip back and forth to make good
connection.
4. Position yourself and free end of 24 inch cable as far away
from battery as possible. Then connect NEGATIVE (BLACK)
charger clip to free end of cable.
WARNING: Do not face battery when making final
connection. Rock clip back and forth to make a good
connection.
5. Select amperage:
6. Follow steps 1-4 in Battery Charger Section.
7. When battery is fully charged, unplug charger from AC
outlet.
WARNING: Do not connect clip to carburetor, fuel lines, or sheet-
metal body parts. NOTE: Attach clips to battery post and twist
or rock back and forth several times to make a good connection.
This tends to keep clips from slipping off terminals and helps to
reduce risk of sparking.
6. Select amperage.
7. Follow steps 1-4 in Battery Charger Section K.
8. When the battery is fully charged, unplug the charger from
the AC power source.
9. Remove charger clips from (1) chassis and (2) battery pole
