6. Connect the red positive (+)
cable to the positive (+) terminal
of the dead battery. Use a
remote positive (+) terminal if the
vehicle has one. 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.
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.
Notice: Your vehicle uses the
unpainted radio antenna bracket
as a remote negative ( ) terminal.
Move the antenna coax 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
your vehicle. The repairs would
not be covered by the 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.
