CAUTION:
{
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a flashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the
battery installed in your new vehicle.
But if a battery has filler caps, be sure the
right amount of fluid is there. If it is low,
add water to take care of that first. If you
do not, explosive gas could be present.
Battery fluid contains acid that can
burn you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, flush the place with water and get
medical help immediately.
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 the vehicle has one.
Negative will go to a heavy, unpainted metal
engine part or to a 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.
