What is the reason for the ignition phenomenon when the negative electrode of the car battery is con

When connecting the battery, it is normal to have sparks, because when the electrical appliance is in a stop state, there will be a current when the power is turned on, so it is normal to have sparks, and cars and electric vehicles are the same.

When charging the vehicle, it should be done outdoors as much as possible, or the battery should be removed and charged separately. The charging line should choose the appropriate wire diameter, the line laying should be fixed and installed, and the short circuit and leakage protection device should be installed.

Precautions for battery maintenance:

Do not store it without electricity:

When the battery loses power, it is easy to sulfate, and the lead sulfate crystals are attached to the plate, blocking the ion channel, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time, the more serious the damage to the battery.

This is a normal phenomenon, whether it is a positive pole or a negative pole, there will be a spark at the moment of connection, this is because some electrical equipment on the car is not controlled by the electric door, such as anti-theft system, remote control system, clock, etc., they have been using electricity, so when connecting the battery, it is equivalent to closing the switch, there will be an electric spark.

This is a normal phenomenon, indicating that there are electrical devices working when connected, such as the standby part of the computer, etc., even if the vehicle is not started, but the weak current part is working, there is a loop, so this situation will occur.

I think the situation you mentioned should be that the positive level of the battery is not connected.

Summary. Dear is happy to answer for you, dear, it has an impact. The positive and negative poles of this battery are touched together, and the probability of damage to this battery is about 80%.

Sometimes this will not be damaged, sometimes the battery will be damaged at this moment, because after the positive and negative electrodes are touched together, a short circuit will be formed in the battery, and the current generated in an instant is relatively high, if the current generated is particularly high, it will burn out the plate in the battery. Therefore, in this case, the probability of damaging the battery is 80% and 20% likely, and the battery is not damaged, so this is uncertain, and it can only be determined after specific inspection. If you can test the battery after the collision in this vicinity, use the battery tester to test the battery, if the voltage of the battery is normal, and the service life is normal, then there is no problem, then there is no damage.

Dear is happy to answer for you, dear, it has an impact. The positive and negative poles of this battery are touched together, and the probability of damage to this battery is about 80%. Sometimes this will not be damaged, sometimes the battery will be damaged at this moment, because the positive and negative electrodes are laughed at after touching each other, a short circuit is formed in the battery, and the current generated in an instant is relatively high, if the current generated is particularly high, it will burn out the plate inside the battery.

Therefore, in this case, under normal circumstances, the damage to the battery can be touched and modified at 80%, and there is a 20% possibility of clearing, and the battery is not damaged, so this is uncertain, and it can only be determined after specific inspection. If you can test the battery after the collision in this vicinity, use the battery tester to test the battery, if the voltage of the battery is normal, and the service life is normal, then there is no problem, then there is no damage.

About two or three months ago, to a friend car electricity, after the electricity two lap the line accidentally bumped together for 5-6 seconds to clear the loss, at that time the car idle state, I immediately took off the tie talk of the wire, there was no problem, in recent weeks the car idle unstable, sometimes fire, yesterday afternoon the car suddenly did not ignite, the ignition coil has electricity, fuel injector spray, on the answer to the god is not hit, check for a long time did not find the reason, no problem, what is the reason.

Why don't you speak. This can be caused by a problem with the engine's ignition system or air intake system.

Ignition is no problem.

Another problem is that the engine failure light of this car never turns on, and the key industry does not turn on.

Kiss. It's usually a problem with the engine computer board.

The car ran out of power, and the battery was connected to the fire and burned it again, and then the new battery was replaced, and the car instrument did not respond, only flashing the yellow light, what happened.

The computer won't burn out, and if there is a fuse, see if your battery and fuse are damaged.

It's not that serious. It is estimated that the battery is broken, so replace the battery.

The fuse should be burned first, and whether the computer will break or not depends on the character.

In this case, the computer is generally not burned, so check the fuse box first to see if the fuse is burned.

You check the fuse first, just next to the positive electrode, to see if it burns, replace it, and then try it on the power, it shouldn't be a big problem, good luck.

What should I do if BYD S6 is tied to the wrong plus or minus?

1. It may be that the battery is out of power or the battery voltage is insufficient, and the engine cannot be ignited.

2. There may be two reasons why the engine cannot ignite, one is that the starter can be heard rotating but the engine cannot start; One is that there is no sound at all. First of all, it may be a circuit problem: fuse blowing, high-voltage coil breaking, low-voltage circuit breaking, center ignition wire falling off, and splitter head leakage.

Electronic faults are mainly caused by the wide finger of the battery and the problem. At this time, it is necessary to check the battery or battery.

This situation can cause the line to burn out and the fuse to blow out. If you're unlucky, you might burn out some of the appliances that haven't been unplugged.

Other possible reasons for the reversal (smoke):

1. The battery life may be reduced or damaged;

2. The relevant lines are burned;

3. The controller may be short-circuited or burned (or the internal components are burned).

4. The deformation of the internal plate of the battery may accelerate the aging; It may even be reversed.

Generally, there is a "smoke" phenomenon, the problem is more serious, and the owner is not familiar with the situation and it is recommended to send it directly for repair.

A car battery, also known as a battery, is a type of battery, and its working principle is to convert chemical energy into electrical energy. Usually, people refer to batteries as lead-acid batteries. That is, a battery mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution.

<> if you find that the rescue battery is reversed, the first thing to do is to disconnect the wire in time, and then connect the two connectors of the battery, the purpose of which is to release the reverse accumulated electricity.

Then press the correct level to connect, and if everything is fine, it's fine. The correct way to wire is: first turn off the power supply of the rescue vehicle, so as not to cause a short circuit in the vehicle circuit and damage to the vehicle's electronic equipment due to negligence by connecting the positive and negative poles of the battery.

I have heard that some car owners did not turn off the power of the vehicle when taking the power, and connected the positive and negative poles in the opposite direction, which finally caused the vehicle's audio system to fail, so it is best to wait for the wire to confirm that the connection is correct before turning on the power to start the vehicle.

Summary. Hello, happy to answer your <>

The positive and negative poles of the car battery are reversed and cannot catch fire: 1After the positive and negative poles of the battery are reversed, the vehicle can definitely not be started, and it can also affect the damage of the vehicle's electronic components.

2. Most of the electronic components such as relays after the positive and negative poles of the battery are reversed, because they are not sensitive to the direction of the current, and most of them will not burn out if the voltage is not high. The problem that arose was the burnout of the fuse and some of the regulating units. 3. There are diodes in many regulating units, and the characteristics of the diodes are unidirectional, of course, once the reverse voltage is added to affect the breakdown of the diode, then it will cause a short circuit in the positive and negative poles of the battery, and the instantaneous current will be too large and the main fuse will be burned out.

These units were also damaged.

Kiss The positive and negative poles of the battery are reversed, and they can't catch fire.

Now I can't hit it even if I pick it up.

Kiss Check for circuit failures and spark plug carbon deposits and ignition system failures Oh.

The first one was reversed, and there was no fire. Later, when I picked it up, I couldn't hit it, only the sound of the motor. The gauge light is also normal.

You need to check for faults in the circuit. Repair engine failures.
