remote negative ( ) terminal if
the vehicle has one.
Do not connect positive (+) to
negative ( ) or you will get a
short that would damage the
battery and maybe other parts
too. And do not connect the
negative ( ) cable to the
negative ( ) terminal on the
dead battery because this can
cause sparks.

cable to the positive (+)
terminal of the vehicle with the
dead battery.

good battery. Use a remote

vehicle has one.

terminal of the good battery.
Use a remote negative ( )

negative ( ) cable to the metal
bracket that is bolted to the
engine and supports the
resonator, on the vehicle with
the dead battery.
10. 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.

connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
