For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the 

6.6 

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.
When disconnecting the charger, turn all switches to off, disconnect the AC 

6.7 

cord, remove the clip from the vehicle chassis and then remove the clip from 

the battery terminal.
See CALCULATING CHARGE TIME for length of charge information.

FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE.

7.

A spark near the battery may 

cause a battery explosion. To 

reduce the risk of a spark near the 

battery:

Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post 

7.1 

usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
Attach at least a 24-inch (61 cm) long 6-gauge (AWG) insulated battery cable 

7.2 

to the NEGATIVE (NEG, N, -) battery post.
Connect the POSITIVE (RED) charger clip to the POSITIVE (POS, P, +) post 

7.3 

of the battery.
Position yourself and the free end of the cable you previously attached to the 

7.4 

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.

Do not face the battery when making the final connection.

7.5 

When disconnecting the charger, always do so in the reverse order of the 

7.6 

connecting procedure and break the first connection while as far away from the 

battery as practical.
A marine (boat) battery must be removed and charged on shore. To charge it 

7.7 

onboard requires equipment specially designed for marine use.

BATTERY CHARGING – AC CONNECTIONS

8.

Risk of electric shock or fire.

This battery charger is for use on a nominal 120-volt 

8.1 

circuit and has a grounded plug that looks like the plug 

illustrated. The charger must be grounded to reduce 

the risk of electric shock. The plug must be plugged 

into an outlet that is properly installed and grounded in 

accordance with all local codes and ordinances. The 

plug pins must fit the receptacle (outlet). Do not use with 

an ungrounded system.

DANGER

 – Never alter AC cord or plug provided – if it does not fit the outlet, 

have proper grounded outlet installed by a qualified electrician. Improper 

connection can result in a risk of an electric shock or electrocution.
