it to the positive (+) terminal of
the good battery. Use a remote
positive (+) terminal if the vehicle
has one.
7. 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 a remote negative ( ) terminal
on the vehicle with the dead
battery. On your van, use the
unpainted radio antenna bracket
as a remote negative ( )
terminal.
8. Connect the other end of the
negative ( ) cable to the
negative ( ) terminal location on
the vehicle with the dead battery.
On your van, use the unpainted
radio antenna bracket as a
remote negative ( ) terminal.
Vehicle Care
Caution
The vehicle uses the unpainted
radio antenna bracket as a
remote negative (-) terminal.
Move the antenna coaxial cable
out of the way before clamping
the negative jumper cable to the
fixed antenna bracket. Avoid
touching the negative cable clamp
to the air conditioning line. Failure
to do either of these could
damage the vehicle. The repairs
would not be covered by the
vehicle warranty.
9. Now start the vehicle with the
good battery and run the engine
for a while.
10. Try to start the vehicle that had
the dead battery. If it will not
start after a few tries, it
probably needs service.
