6. Connect the red
positive (+) cable to the
positive (+) terminal of
the vehicle with the
dead battery. Use a
remote positive (+)
terminal if the vehicle
has one.
7. Do not let the other end touch metal. Connect it
to the positive (+) terminal of the good battery.
Use a remote positive (+) terminal if the vehicle
has one.
8. Now connect the black negative ( − ) cable to the
negative ( − ) terminal of the good battery. Use a
remote negative ( − ) terminal if the vehicle has one.
Do not let the other end touch anything until the
next step. The other end of the negative (
− ) cable
does not go to the dead battery. It goes to a heavy,
unpainted metal engine part or to the remote
negative (
− ) terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative ( − ) cable to
the remote negative ( − ) terminal, on the vehicle
with the dead battery.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably
needs service.
