To date, very few drivers know how to check the ignition coil independently, although this knowledge every day get up more and more urgent. After all, due to incorrect or improper operation of this device on the road may occur undesired and unexpected stops. Timer and the ignition coil are the most important nodes because provide a full and uninterrupted operation of the vehicle. Various defects in the device or its breakage can lead to serious disruptions in operation of the vehicle, but sometimes also to absolute engine stop operation.

Tools assistants to verify the ignition coil

To check the ignition coil, you need to equip a multimeter, which has two operating modes - checks for ohms and volts. In addition, the test can be done the old, but rather a common way. To do this, you must identify the spark between the vehicle body and a candle. However, it is not always safe and can lead to the absolute output of the mechanism of action.

Ignition system, how it works

Well, let's see why the ignition system and where it is located in the car. Timer is at the top of the motor, and it receives a low-voltage current. It passes from the battery via the onboard network and transformed into a high-voltage, when placed on the ignition coil. It is in the timer high-voltage current is discharged to the primary wire which is on the spark plug. This happens with the help of contacts and slider on the device cover.

Further, the candle that screwed into all cylinders of the engine, a spark is supplied to the combustion chamber of the fuel composition, and wherein the produced inflammation. In such a situation, the power and quality of the current very much depends. For example, the inflammation does not happen, if the current is not filed on time, and the ignition coil should be responsible for the optimum strength of the current.

If the coil or the entire ignition system is not working properly or is ineffective, the current will not be properly fed. As a result, the engine starts, will not happen, even though the starter is rapidly rotate the crankshaft. Also, in this case, the muffler can be a smell of gasoline, which indicates a problem with the ignition of the air-fuel composition.

Faults in the ignition system, what are the causes, how do you know

Yield element failure may occur for several reasons, however, the main options are the following motifs:

1.Starenie specific node or all elements of the ignition coil.

2.Povrezhdenie device during ignition of a spark at admission to the desired destination.

3.Takzhe, problems can occur if the installed candles or substandard wiring slaughtered.

Check the ignition coil and diagnose problems can be well-known and quite popular method:

1.Neobhodimo reverse voltage wire and one of the candles.

2. After you need to miss a candle in the wiring, which would analyze the spark.

3.Odnovremenno the preceding paragraph is required to start the engine if the spark between the body and slipped a spark - which means that the device is working properly. If the spark is absent, the coil current and does not need to repair or to replace it.

Ordinary drivers who are not really aware of all the details of the ignition system, the engine and other mechanisms, often used by the method described above. However, not everyone knows that you can not check them every tramblernuyu ignition system. There are vehicles that at such a verification fails even working coil. For example, Honda's 2001 issue.

Furthermore, the engine may stall and for other reasons. Therefore, before testing the coil, it is necessary to pay attention to the wires, which can have breakdowns or spark plugs.

Very often, the 'green' motorists because of their inexperience and forgetfulness, check out the candles on the performance or try to replace the coil, although, in fact, the reason that the vehicle will not start, it may be very simple, such as the lack of fuel in the tank. It is said that to carry out such checks in the field is not highly recommended, it is better to do it in his garage.

The ignition coil device and its

If you carefully checked all the elements that are responsible for the power supply, but the result remained the same, it is necessary to inspect the coil. However, for starters, let's look at the details of what it is. Undoubtedly, each unit consisting of housing, not capable of transmitting current. In this situation, it is made of hard rubber - material which is a good electrical insulator, it consists of high - vulcanized rubber with 50% of the sulfur content, it has excellent color and black to machine.

On top of the coil should be cover, wherein the central terminal is located. Another design is within the core, the central spring terminals, the insulating material, screws and so on. Often, the mechanism can be damaged due to any internal damage anything, but there are situations where current can break into the housing.

By operation and ignition coil with a multimeter tramblera

For the competent inspection work of this part, unscrew the clamp and detach the connector harness from tramblera. Next, we take the meter and tune it to the voltmeter mode. After that, it is necessary to connect one end to the vehicle body, that is, to the mass, and the other - at the conclusion of the coil. However, it should be twelve volt voltage. If the voltage is not at all, then breaking in the engine control system or the electrical circuit tramblera.

Next to be checked for open coil primary winding. To do this, you must switch the multimeter in ohmmeter mode and put the reel-to-conclusions: first, A - B, then B - C. As in the first and in the second case, it is not necessary that the resistance would have sunk lower than two ohms. However, if this should happen, then there is a break and have to replace the device.

With regard to the secondary winding of the coil, then it must be checked in the same way as the primary. They differ only in that the ohmmeter reading should not be less than five ohms.

In the end, it is required to check the timer on the closure of the two windings. It is necessary again to an ohmmeter connected mode terminal leads in coil A and to one of the high-voltage outputs. The circuit will be opened in case of resistance to infinity.

Electronic ignition principle and dignity

The principle of operation of this system is the rotation of the magnet, in which the number of poles must match the number of the number of cylinders. Upon rotation of the magnet, an alternating current in the coil a special controller.

This type of ignition system is capable of operating at different temperatures - from -40 to +80 degrees Celsius. On this correctly positioning it in the engine compartment. Installation of the ignition coil and the sensor must be done in the field for a conventional (standard) ignition system. It is said that electronic ignition system is much more efficient than conventional, and their service life is much higher.

Electronic Ignition System Diagnosis

To diagnose the ignition system must be checked breaks in the wires, which are located between the switch and the sensor. Scheme electronic ignition system is arranged so that breakage can also be associated with breakage of wires that connect the coil itself with the switch or circuit breaker.

It is said that the smell of burnt coil may, without any checks indicate to you that it is worthless. A electronic ignition system does not need adjustment and securely perform their duties for a long time.
