Probably every driver has faced such a problem as a dead battery. This is especially true in winter cold. In this case, the problem is most often solved by "lighting up" from another car. What do I need to do? How to light a car from a car?

Is the battery really dead?

Before you start to “light up” the car, you should find out for sure that the reason for the non-working state lies precisely in it. Signs of a dead battery are a weak glow of the headlights or its complete absence, a dull sound of a horn, a howl of an alarm. In this case, the starter does not work. When various energy consumers are turned on, a slight crackling sound is heard (for example, when turn signals, emergency lights are turned on).

Sometimes almost the same symptoms are observed when the power terminals of the battery, body or engine are poorly connected. But, as a rule, the cause is a dead battery. In this case, you should look for a "live" car to "light up".

Whatneeded?

How to “light up” a car from a car, what is needed for this? Well, of course, firstly, a car with a charged battery, from which you will have to start. Secondly, special wires are needed. Some drivers sometimes use some kind of handy wires, which, in general, are not intended for this. Is it possible to light a car in this case? It is possible, but it is still recommended to buy a specially designed cable, which is equipped with terminals at the ends. Using this wire is safer and easier.

Safety

How to light up a car? Safety precautions must be followed. Otherwise, you may damage the machine or injure yourself.

First you need to turn off the car and turn off all electrical appliances. Otherwise, the generator may fail. Cars should be as close to each other as possible, but in no case should they touch. When connecting the batteries, it is necessary to act in strict sequence, observing the polarity. This will eliminate the possible occurrence of a short circuit. Also, in strict sequence, you need to act when disconnecting the wires.

It is not recommended to use a small car to “light up” a large car, as the “donor” may itself be discharged as a result. Also, you can not use a gasoline engine to start a diesel engine, becauseas in this case, the forces are also unequal.

To connect, you must use whole wires, without damage, kinks. The terminals must be made in the form of "crocodiles" to ensure a reliable and high-quality connection.

Is it harmful to "light up" a car? No, if you follow safety precautions and all precautions.

Sequence of actions

How to "light up" from another car? Proceed as follows:

• Cars are placed with hoods to each other as close as possible, the engine of a running car must then be turned off.



• Batteries are connected using wires.
• Launch of a donor car. It should idle for about five minutes, after which the car starts with a dead battery. The second car should run at medium speed for about 5-10 minutes.
• Disconnect wires. In this case, you need to act in strict sequence. It is also recommended to turn on any electrical device in a charged car (for example, radio, heated rear window, etc., but not headlights, the bulbs in them may be damaged) to prevent a power surge.
• The machine must run for at least another 20 minutes to fully charge the battery. Therefore, you should make a long trip at high speed (2000 rpm).

During the process, it is recommended to remove the key from the ignition and close all doors. This is done becausewhen charging, an alarm may sound. As a result, the doors may close. And if you keep them open, then a failure in the alarm system is possible. Now it became clear how to “light up” a car from a battery?

Sequence of connecting and disconnecting wires

It is very important to connect the wires correctly when lighting up cars. You need to act in strict sequence:

• The first wire must be connected to the positive terminals of the machines.
• The second cable connects the negative terminal of the donor car and any mass (eg, cylinder block, engine). It is impossible to connect the wire to the battery minus of a discharged car, since all the energy will go to the starter, and not to the battery. And then the whole process will go to waste. When connecting, you must act carefully, you can not touch the positive terminal with the negative terminal. Otherwise, a short circuit may occur.

After the car is recharged, disconnect the wires. You also need to act in strict sequence, the reverse of the connection. First, the negative terminals are disconnected, then the positive ones.

It is important to remember that cars can have different wiring patterns. Therefore, it is recommended that you first read the operating instructions for the equipment. As a rule, the manufacturer mentions in it the nuances of this process.

"Lighting" from the injector and machine

Is it possible to "light up" from an injection car? Will the "donor" or "patient" be harmed? Answer: "You can."The main thing is to know how to properly “light up” an injection car. But at the same time, precautions must be taken. If you follow them, then the whole process will go right and the "iron horse" will be back in service.

The process is similar to "lighting up" cars with a carburetor engine. At the same time, safety measures must be observed to prevent a short circuit and injury.

Also, many are interested in the question - is it possible to give a "light" to a car with an automatic transmission? It should be noted that the type of gearbox in no way affects the ability of the machine to charge the battery of other equipment. Actions are carried out according to the general principle of "lighting up" the battery.

When "lighting" a modern car, it is also worth considering that if you do not turn off the engine of the "donor", then this threatens not only with a breakdown of the generator. This can also lead to a failure of electronic systems, which are stuffed with cars with an injector and an automatic machine.

Why is my battery draining

The reasons may be different. Often the battery is discharged due to excess energy consumption by various elements. This can be, for example, headlights on, heated seats and rear windows, and so on. As a result, the car may not start.

The battery can be discharged from severe and prolonged cold. This is especially true for old batteries, the resource of which has already been significantly reduced. For them, sometimes temperatures below -15 degrees are enough, and in the morning the car will not start. The following may also cause discharge.situations:

• poor wiring insulation;
• bad battery;
• faulty alternator to recharge;
• faulty alarm operation;
• connection of non-standard electrical equipment.

To diagnose a battery charging problem, close all doors and turn off all electrical appliances. After that, an ammeter is connected to the battery circuit and the current value is measured. The indicator should be no more than 50 mA. If the value is greater, then you should look for a malfunction. To do this, turn off the fuses one by one. When the current value drops, a leak should be looked for in that circuit.

Charging the battery

We have considered how to “light up” a car correctly. But you can completely exclude this situation. To maintain a he althy state of the battery during its operation, it is necessary to be guided by the recommendations from the manufacturer. You can also charge the battery, which many drivers do. This process can be done without removing the battery from the car. This is done, as a rule, in the garage, where there is access to a 220 V network. It is from it that the charger is powered. At the same time, precautions should also be taken. Before charging, be sure to remove the terminals from the battery. If during the process the battery becomes very hot, then it is necessary to disconnect it from the power source.

At negative temperatures, the process progresses very slowly. As a result, the battery maydo not charge. Therefore, it is recommended to connect the battery to a power source at positive air temperatures.

The nuances of "lighting up"

There are also situations when there are difficulties when "lighting up" the car. For example, in some cars, the battery is located in an unusual place for everyone: in the trunk, under the chair, under the floor, etc. How to “light up” the car from the car in this case? Such machines usually have special terminals located under the hood and marked with a “+” symbol or the inscription POS, or a “-” or NEG.

In some cases, the "iron horse" stands in a place that is very difficult or impossible to reach. How to “light up” an injection car in this situation? You can save the car if you roll it a little in one direction or another for the entrance of another vehicle. You can drive the car in tow to another, more convenient place. And another option is to use several sets of wires (as a rule, they are short). In the latter case, you should be especially careful not to allow the cable to come into contact with other elements and with each other. It is best to use electrical tape to connect the wires.

Violation of traffic rules

One more situation needs to be taken into account. If a non-working car is on the road, then the second car will have to stand in front of the movement. This can be regarded as a violation of traffic rules, which may threaten the deprivation of a driver's license. Of course, traffic police officers withunderstanding will treat the assistance provided, but still. To avoid an unpleasant situation, you need to set an emergency stop sign, pre-record all maneuvers on cameras (if possible).

Thus, it is clear how to “light up” a car from a car, what is needed for this and what precautions need to be taken.
