you need to use a 12-volt jumper system.
You will damage your starting motor,
ignition system, and other electrical parts if
you connect them to a 24-volt power supply
(either two 12-volt batteries in series or a
24-volt generator set).
*
[RE01300( ALL)03/95]
2. Do not disconnect the battery of the disabled
vehicle. You could damage the vehicle's
electrical system.
*
[RE01400( ALL)04/95]

the positive (+) terminal of the discharged
battery. (You can connect either jumper cable
to the positive (+) terminal, as long as you
use the same cable for both positive
terminals.) Most jumper cables have a red
cable and a black cable. The red cable is
generally used for the positive terminals and
the black for the negative ones.
*
[RE01900( ALL)04/95]
2. Connect the other end of the first cable to
the positive (+) terminal of the booster
battery.
*
[RE02000( ALL)05/95]
3. Connect one end of the second cable to the
negative (-) terminal of the booster battery
Ð NOT to the discharged battery.
*
[RE02100( ALL)04/95]
4. Connect the other end of the second cable to
a good metallic surface on the engine or
frame of the disabled vehicle.

*
[RE04275(BEF )05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.
*
[RE04280(BEF )10/94]
Extended use of other than matching size spare
tires on a Traction-Lok axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.
