Hi C is the Answer I believe
<span>(1) Connect one red clamp to the positive (+) battery post of the "dead" battery.(2) Connect the other red clamp to the positive (+) post of the good battery.(3) Connect one black-end clamp to the negative (-) post of the good battery.(4) Carefully connect the other black-end clamp to some large metallic part of your car's engine block. Never connect it to the negative (-) post of the "dead" battery because this causes sparking which could ignite battery gases.<span>hope this helps </span></span>
