Connecting The Jumper Cables - Lincoln 1997 Town Car Owner's Manual

Connecting the jumper cables

1. Connect one end of the first jumper cable to
the positive (+) terminal of the discharged
battery. (You can connect either jumper cable
to the positive (+) terminal, as long as you use
the same cable for both positive terminals.)
Most jumper cables have a red cable and a
black cable. The red cable is generally used for
the positive terminals and the black for the
negative ones.
2. Connect the other end of the first cable to the
positive (+) terminal of the booster battery.
3. Connect one end of the second cable to the
negative ( ) terminal of the booster battery —
NOT to the discharged battery.
4. Connect the other end of the second cable to a
good metallic surface on the engine or frame of
the disabled vehicle.
