For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the battery
charger to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect the
NEGATIVE (BLACK) clip to the vehicle chassis or engine block away from the battery. Do
not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a
heavy gauge metal part of the frame or engine block.
6.6
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery
charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the
POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do
not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a
heavy gauge metal part of the frame or engine block.
6.7
When disconnecting the charger, turn all switches to off, disconnect the AC cord, remove
the clip from the vehicle chassis and then remove the clip from the battery terminal.
6.8
See CALCULATING CHARGE TIME for length of charge information.
7. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE
WARNING: A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
7.1
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually
has a larger diameter than the NEGATIVE (NEG, N, -) post.
7.2
Attach at least a 24-inch long 6-gauge (AWG) insulated battery cable to the NEGATIVE
(NEG, N, -) battery post.
7.3
Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post of the battery.
7.4
Position yourself and the free end of the cable you previously attached to the NEGATIVE
(NEG, N, -) battery post as far away from the battery as possible – then connect the
NEGATIVE (BLACK) charger clip to the free end of the cable.
7.5
Do not face the battery when making the final connection.
7.6
When disconnecting the charger, always do so in the reverse order of the connecting
procedure and break the first connection while as far away from the battery as practical.
7.7
A marine (boat) battery must be removed and charged on shore. To charge it onboard
requires equipment specially designed for marine use.
8. BATTERY CHARGING - AC CONNECTIONS
8.1
This battery charger is for use on nominal 100 - 240 volt circuits.
DANGER
– Never alter AC cord or plug provided – if it does not fit the outlet, have proper
outlet installed by a qualified electrician. Improper connection can result in a risk of an
electric shock.
8.2 Recommended minimum AWG size for extension cords for battery chargers:
AC input rating, amperes*
AWG size of cord / length of cord, feet (m)
At least

*If the input rating of a charger is given in watts rather than in amperes, the corresponding
ampere rating is to be determined by dividing the wattage rating by the voltage rating.
For example: 1250 watts/125 volts = 10 amperes
