Basically, we are talking about a kind of wire or cable which is a friend
in need and a friend indeed! Have you ever wondered, you are going to
a long drive with your beloved girlfriend through a deep wood. The
roads are calm and quiet as no one can be seen around. At such time
your car engine dies and also there is no possibility to find a mechanic
garage nearby to seek help. Suddenly you see another car coming
through the road, what do you do then? Ask to get a lift from an
unknown person? Nope! If that man or woman is friendly enough, he or
she may just be able to recharge your car and help you pass through
that sudden hazard.
The question is how is that even possible? Your new set of jumper
cables say hello to you! Your car battery died but it can be recharged
from another charged car battery by using these jumper cables. It just
makes the power from the charged battery to jump to the dead one, as
for this it got the name of “jumper cables”. After you carefully attach
the cables to the batteries, power flows from the charged one, to the
dead battery, if you can initiate your engine then, Halleluiah! You’re
saved.
According to Collin’s Dictionary, Jumper Cable is a pair of long, thick,
insulated electrical wires with large, clamp like terminals. It is used to
start a motor vehicle’s engine by connecting its dead battery to a live
battery.
If you want to properly use jumper cables on your vehicle, make sure
that the battery on the good Samaritan’s vehicle has at least as much
voltage as your own. As long as you hook up the cables properly, it
doesn’t matter whether your vehicle has negative ground and the other
vehicle has positive ground, or your vehicle has an alternator and the
other vehicle has a generator.
But there is also a safety precaution for you to follow, if either vehicle
has an electronic ignition system or is an alternatively fueled vehicle,
the use of jumper cables may cause harm to it.
