The car can not start there are a variety of factors caused, first do not rush to replace the new battery, it is possible that this money will be spent in vain. There will be many reasons for abnormal start-up, such as insufficient battery power, no storage power, problems with the power line, poor corrosion and contact of the battery pile head, engine failure, battery life expiration, etc., these factors may make the car unable to start.
A friend's car start is a bit strange, during the day can start, put a night on the start can not start up, he also thinks that the battery's terminal post is loose, check no problem, there is no corrosion of the situation, this happened for many consecutive days, he did not think much about it to the car battery store to spend more than 500 yuan to replace a new battery. Just use a few days OK, the back will gradually happen with the previous situation without changing, how to start during the day is fine, put a night on the 2nd day can not start up.
The owner of the car changed the battery, spent hundreds of dollars, did not solve any problems, where did the problem occur? In fact, some problems can be fixed for tens of yuan. Today we come to analyze, how to spend 20 yuan to fix this problem, you can refer to it, in the future encounter this situation can avoid the occurrence of pit situation.
What problems usually occur when the car can't hit
The car can not hit, the battery problems, such as battery power is insufficient, the battery has aged and can not store electricity, there is a long time to put, power loss, line corrosion caused by short circuit, battery pile head contact is poor. External factors such as spark plug failure, fuel filter failure, starting motor failure, engine carbon deposition, engine damage, engine water inlet ignition system failure, fuel shortage, etc.
Usually the most common problems are battery power loss, poor contact, insufficient or no engine storage, ignition system failure, starting motor failure, and engine failure.
When the car starts to light, only the click is heard, and it has not been able to fire, and finally the sound of clicking is getting weaker and weaker, which indicates that there is a problem with the battery. There is a time to click the sound is very large, that means that the power is very sufficient, but the engine does not respond, there may be a failure around the engine, the audio-visual ignition sound is normal, this is the ignition device and the gas fire in the cylinder can not be ignited instantly, it may be insufficient oil supply, can not start. There is time to start when you can occasionally hit, there is time is not able to hit, repeatedly, there will be spark plugs of the ignition to make a long time, carbon deposition or burn loss.
Cars can be sent during the day, and there is no reason to send them overnight
Some drivers say that the battery is insufficient, the temperature is high during the day, the residual power of the battery can be sent, and the power is insufficient at night due to the temperature reduction, and the 2nd morning cannot be started, which is also correct.
Some cars will have this situation, the owner of the car suspects that the battery is not working, anxious for five or six hundred yuan for a new battery, after trying for a week this problem still exists. The owner had to find another reputable repair shop to do further inspections to find out where the problem was.
Usually in some repair shops will be made such two choices, in order to make more money, small problems he will give you as a big problem to deal with, like this battery problem, he just did not seriously check the analysis, to find out where the fault is? After a preliminary judgment, it was believed that there was a problem with the battery, so I directly spent 600 yuan for a new one.
After replacing the new battery, after debugging can start normally, this is the battery storage is relatively full, starting the car is no problem, indicating that there will be no problems in the line, oil, spark plug ignition.
The owner drove back for a week, can start normally, after a week is still with the problem before the change. How to open during the day can be, put a night can not hit, the owner of the car believes that the problem has not been dealt with, he does not believe in the repair shop, found another repair to do the inspection.
The car started 600 yuan and was not repaired, and it only cost 20 yuan to repair it
Drive to the repair shop first to check the voltage of the battery, my friend master started the car to measure the voltage is only 11.3V, the normal voltage of the battery is 13 ~ 14V, in the case of not opening the headlights, the power generation voltage is very normal, open the headlight detector on the voltage display on the drop is very serious, to eleven o'clock a few volts. Under normal circumstances, the headlights should not be lowered, and should be maintained at a voltage of 13 ~ 14V.
After detection, the power generation of the headlights is more than 13V, it is normal, the voltage of the headlights is reduced, the power generation is not enough 12V, there is a loss state, it may be that the generator is broken, and it needs to be dismantled to check what problems occur inside.
Engines like this have similarities with brushed engines of electric tricycles, which run with carbon brushes and magnets that produce friction and ignition to generate electricity. Many times this tricycle can not start or do not go, we have to first check these aspects, generally there will be carbon brush wear and tear, can not work properly, thereby affecting its power generation is not enough.
The engine is removed to check the rotor and coil, as well as the bearings are no problem, the carbon brush is taken out of the wear is very small, can not be well contact friction, discharge is affected.
Find a carbon brush or carbon brush box to install it, install the pulley, start it up and test it again. When removing the wire, we should pay attention to removing the main fire wire of the battery and the end of the motor, repair it and then install it to prevent ignition.
After installation, the car starts up to show that it has risen to 14V, which is normal, and then turn on the headlight test, the voltage is stable at 13V, so it is very normal, if the voltage continues to drop below 12V, it means that it is not normal.
This operation is not very simple, only used more than 20 yuan of small accessories, the start of abnormal situation to deal with, is not very cost-effective?
Duo Bin suggested: Car owners will encounter this situation in the future, do not spend a high price directly to replace the battery, too wasteful of money. Often many times the start can not be caused by a variety of factors, first of all, to do a simple troubleshooting step by step, find out the fault problem, in order to deal with it more accurately, so that it saves money and trouble, and does not waste accessories.
I shared this article can give the owner friends a reference, in the future encounter this kind of problem, will not directly come up to spend hundreds of yuan to replace the battery, has not solved the problem, maybe you only spend a few tens of yuan to fix the problem.
