Attach the output cables to the battery and chassis as indicated below. Never 

3.1 

allow the output clips to touch each other.
Position the dC cables to reduce the risk of damage by the hood, door and 

3.2 

moving or hot engine parts. NOTE: If it is necessary to close the hood during 

the charging process, ensure that the hood does not touch the metal part of 

the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.

3.3 

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

3.4 

usually has a larger diameter then the NEgATIvE (NEg, N, -) post.
determine which post of the battery is grounded (connected) to the chassis. 

3.5 

If the negative post is grounded to the chassis (as in most vehicles), see step 

3.6. If the positive post is grounded to the chassis, see step 3.7.
For a negative-grounded vehicle, connect the POSITIvE (REd) clip from the 

3.6 

jump starter 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.
For a positive-grounded vehicle, connect the NEgATIvE (BLACK) clip from 

3.7 

the jump starter 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 jump starter, turn all switches to off (if applicable), 

3.8 

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

battery terminal.
