10-58 Vehicle Care
5. Check that the jumper cables do
not have loose or missing
insulation. If they do, you could
get a shock. The vehicles could
be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if equipped.
Negative ( ) will go to an
unpainted metal part or to a
remote negative ( ) terminal if
equipped.
Do not connect positive (+) to
negative ( ) or you will get a
short that would damage the
battery and possibly other parts
too. Do not connect the
negative ( ) cable to the
negative ( ) terminal on the dead
battery because this can cause
sparks.
6. Connect the red positive (+)
cable to the positive (+)
terminal (1) of the dead battery.
Use a remote positive (+)
terminal if equipped. Do not let
the other end touch metal.
Connect it to the positive (+)
terminal (4) of the good battery.
Use a remote positive (+)
terminal if equipped.
7. Connect the black negative ( )
cable to the negative ( )
terminal (3) of the good battery.
Use a remote negative ( )
terminal if equipped.
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 the shock
tower, or to a remote
negative ( ) terminal on the
vehicle with the dead battery.
8. Connect the other end of the
negative ( ) cable to the
negative ( ) grounding point (2)
on the shock tower of the vehicle
with the dead battery.
Caution
Make sure the jumper cables do
not touch moving parts in the
engine compartment and that the
cable clamps do not contact any
other metal.
9. Start the vehicle with the good
battery and run the engine for a
few minutes.
10. Keep the engine speed of the
booster vehicle at about
2,000 rpm, and start the engine
of the vehicle being jump
started.
Caution
Do not keep the starter motor
engaged for more than
10 seconds. If the engine does
not start right away, turn the key
off and wait three to four seconds
before trying again.
