The motorcycle doesn t catch fire, and the spark plug doesn t have a spark!!!

Spark plugs for motorcycles.

There is no high-voltage spark that cannot ignite, and it is an ignition system electrical device.

or the fault of the circuit, check whether there is a problem with the spark plug, high-voltage bag, igniter, magneto coil, electric door lock, etc., and whether there is an open circuit or short circuit fault in the line between them. If it is a motorcycle with DC ignition, if the battery is out of power and the rectifier.

Or the charging system line happens to be broken, which will also cause no high-voltage sparks. Some cars also have special stop-off switches and side bracket stop-off switches, so you also have to check whether there are problems with them.

There are many reasons why the motorcycle spark plug does not have high voltage, you can check step by step, it is best to prepare a multimeter in advance, so that it is convenient to measure, first unscrew the high voltage cap on the high voltage line directly to test whether there is high voltage on the cylinder body, if there is high voltage, the spark plug is broken, replace it with a new one to solve the problem, if there is no high voltage can be checked from front to back or from back to front, it is the same, first check whether the high voltage circuit part has poor contact, if there is a reconnection, If not, you can use a multimeter to measure whether the trigger coil is normal, whether the ignition is normal, if it is normal, it means that the high-pressure package is damaged, and it can be replaced.

The motorcycle does not catch fire, the spark plug has no spark, the spark plug is broken, this is the high-voltage coil package burned, and it may be that the battery is losing power, go to the repair shop to test, replace the corresponding accessories, or charge the battery.

In addition to the spark plug itself, there are also wiring problems, ignition high-voltage package problems, magneto coil and trigger problems, etc., which need to be investigated one by one.

Hello. Here's how to check if the spark plug doesn't catch fire. Try it out with a spark plug first.

If the spark plug doesn't jump off the fire. Replace the large wire package and give it a try. If you don't have electricity yet.

Give it a try by replacing another igniter. If none of the above is true. I had to go to a motorcycle shop for repairs.

Hello, this situation is nothing more than a three-pronged problem. One is battery feeding. The second aspect is that the spark plug is malfunctioning. The third aspect is that the high-voltage coil is faulty.

Hello, according to your description, it is recommended to check if the ignition system of the vehicle is faulty, I hope my pair helps, hope, thank you.

Ordinary riders can only replace the spark plug test state, if there is no electricity, you can only find a maintenance worker to repair, circuit failure is not to look at the idea or tutorial will,

Hello, it should be broken, get a new one.

This may be that the battery is out of power, or it may be that the spark plug is broken, you can go to the repair shop and ask the mechanic to overhaul it.

When the motorcycle does not catch fire, check that the spark plug does not have high-voltage electric sparks, which is caused by the failure of various parts of the ignition system, or the wiring between the parts of the ignition system is open or short-circuited, and the wiring plug is loose and virtual, and the contact is poor. If it is an EFI motorcycle, it is also necessary to check whether some sensors, such as inclination sensors, are faulty.

The motorcycle can not ignite because the spark plug does not have a high-voltage electric spark, and it is necessary to check the spark plug, high-voltage package (including high-voltage cap), igniter (or ECU of the electric injection vehicle), magneto stator coil, ignition switch, electric door lock, flame-out switch (if any), etc., and whether there is a broken circuit or short circuit between these parts, as well as the loose virtual connection of the wiring plug and poor contact, etc., the motorcycle does not have high-voltage electricity, which is basically caused by faults in these aspects.

Overhaul motorcycle without high-voltage fault, some electrical devices are best to use the same model of new parts, or confirm the good parts replacement test, some circuits and switches can be detected with a multimeter, find the specific cause of the failure, and then deal with it according to the situation, repair or replace the problematic parts.

The motorcycle does not ignite, and the spark plug does not have a high-voltage electric spark, which is caused by the components of the ignition system, or the faulty wiring between them. In this case, it is necessary to check whether the spark plug, high-voltage bag, igniter, magneto stator coil, ignition switch, electric door lock, flame-out switch (if any), etc. are damaged, and whether the wiring between these components is open or short-circuited, whether the wiring plug is loose and virtually connected, etc., which can cause the spark plug to have no high-voltage electricity, basically these reasons.

It's so simple that no one has judged the failure. A motorcycle engine needs three prerequisites for a normal start, namely an accurate and strong high-pressure spark, good compression, and an appropriately concentrated mixture. As long as these three conditions are met, the engine can be started.

When checking, you can choose to remove the spark plug, it is pressed on the spark plug cap, the metal part of the spark plug is attached to the engine cylinder head radiator, and then press the start button to observe whether there is a strong high voltage, if not, there is a problem with the ignition system. If there is a strong electric spark, you can use your fingers to press the spark plug hole, and then quickly press the starting lever or press the start button to feel whether there is a strong air pressure impact at the fingers. Finally, observe the removed spark plug, if it starts for a long time without ignition, the spark plug should be wet, otherwise it may be due to the carburetor blockage and other reasons that cause the oil supply to be ineffective.

There are many reasons for the failure of the engine to catch fire, if it cannot be solved after simple treatment and inspection, it is better to find someone who repairs the motorcycle, not all faults can be dealt with by yourself.

There are many reasons why the motorcycle can not start, if the spark plug and high-voltage electric ignition are normal, you can check whether the carburetor is blocked or improperly debugged, whether the intake pipe and other hoses related to the engine and carburetor are slightly leaking, whether the valve clearance is too small or not tightly closed, whether the cylinder pressure is insufficient, whether the valve timing is wrong, whether the exhaust pipe is blocked, whether the gasoline is not good, etc., these are also the more common reasons that cause the motorcycle to have high voltage but cannot start.

Hello. There are many reasons why the motorcycle does not ignite, the spark plug is normal, look at the carburetor needs to be cleaned, if there is garbage blocking the oil pump on it, you press a few times on a plastic cap pump pump on the carburetor to try it, and then consider how long the oil and air filter have not been replaced, generally after such maintenance can work normally.

The spark plug of the motorcycle ignition system ignites the combustible mixture in the cylinder, and it is necessary to ensure a certain value of high voltage and an accurate and stable high voltage electric field, otherwise it will cause irregular combustion and early damage to the spark plug, the main reasons are as follows:

1. The flywheel magnet of the motorcycle generator is demagnetized. The magnetic field of the generator of most motorcycle engines is composed of more than two sets of sub-magnetic fields, and when the magnet is demagnetized, the magnetic force of each sub-magnetic field is different, which will make the strength of the adjacent magnetic fields asymmetrical, and the current emitted will fluctuate greatly. In addition, the degree of insulation of the ignition power supply coil decreases, resulting in leakage or local false short circuit, which will also make the output current fluctuate greatly, so that the stability of establishing a high-voltage electric field will be worse.

2. The voltage of the motorcycle spark plug is unstable. The false short circuit inside the ignition coil and the electronic ignition of the motorcycle will cause the ignition coil to be a primary false tie iron, and the high-voltage output is extremely unstable, so that the ignition voltage of the spark plug is out of control.

3. The ignition wire of the motorcycle is in poor contact with the generator. The loose wire connection between the output end of the motorcycle generator and the input end of the ignition coil is easy to cause poor contact at the wire connection, so that the conduction of the current produces "beating" fluctuations, and the disordered current will seriously interfere with the normal ignition function of the spark plug.

How to repair a motorcycle spark plug without ignition? The mechanic teaches you to connect a wire directly and get immediate results.

Either the high-voltage package failed or the copper coil in the generator was reimbursed, and I was reimbursed for the coil that time, so let's replace it. The power supply of the spark plug is through: generator - copper coil - high voltage package - spark plug, these programs work....

A second-hand motorcycle can't catch fire, take out the spark plug and simply repair it can still be used, good.

The nozzle is broken (click if it helps you.)"It works"Thank you! )

The reasons why the spark plug of a motorcycle does not catch fire are:

1. The spark plug is seriously ablated and the carbon deposit is excessive, which may cause the spark to leak and cannot work normally.

2. The motorcycle mixture is too thick, and the valve clearance is improper.

3. The ignition of the spark plug is too early.

MotorcyclesSpark plugsThe reasons for not igniting are:

Motorcycle generator flywheel magnet loses magnetism; The spark plug voltage of the motorcycle is unstable; Poor contact between the motorcycle ignition wire and the generator; quality problems with the spark plug itself; ignition failure; high-voltage packet failure; Magneto coil failure; Ignition switch dust lock tank failure; Poor contact between the ignition wire and the generator; Generators, flywheels, magnets, demagnetization, etc.

Common species

According to the calorific value. There are cold and hot types; According to the electrode material, there are nickel alloys, silver alloys and platinum alloys; If you are more professional, the types of spark plugs are generally as follows:

1. Quasi-type spark pie Chuntong plug: its insulator skirt is slightly retracted into the end face of the shell, and the side electrode is outside the end face of the shell, which is the most widely used.

2. Spark plug with protruding edge: the skirt of the insulator is long, protruding beyond the end face of the shell. It has the advantages of large heat absorption, good anti-fouling ability, etc., and can be directly cooled by the intake air to reduce the temperature, so it is not easy to cause hot spot fire, so the thermal adaptation range is wide.

3. Electrode spark plug: its electrode is very thin, characterized by strong sparks, good ignition ability, and can ensure that the engine forest model can start quickly and reliably in the cold season, with a wide thermal range, which can meet a variety of purposes.

Motorcycle sparks and tongsai do not ignite, yesIt is caused by the failure of the parts of the ignition system, or the circuit between the parts of the ignition system is open or short-circuited, and the wiring plug and switch are loose, virtual, or poorly contacted. It is necessary to check whether there are problems with the relevant parts and wiring of these ignition systems separately, find the specific cause of the fault first, and then repair it according to the situation.

Motorcycle spark plugs do not ignite,First of all, you can try a suitable model of spark plugThe spark plug itself is a wearing part and a consumable part, and it is relatively easy to be damaged. If the spark plug can be ignited after replacing it, it means that the spark plug is the problem. If the spark plug is often damaged and needs to be replaced, the general reason is that the spark plug itself is of poor quality, or the calorific value of the model is not suitable, the engine has a failure to burn oil, the gasoline oil quality is not good, the high voltage is weak, etc., which may cause the spark plug to be easily damaged.

If the spark plug is still not ignited after replacing it, check it separatelyHigh-voltage packs, igniters, magneto coils, ignition switches, electric door locks, and flame-out switchesand whether there is any open circuit or short circuit fault between the sheds of these ignition system components. If it is a motorcycle with EFI, also check the sensors related to the ignition system and whether there is a problem with their wiring. The reason for the failure of the motorcycle without high voltage is in the ignition system parts and their wiring, as long as the qualified parts and lines are checked respectively, it is not difficult to check out the specific problem.

There are many reasons why the spark plug of a motorcycle is not ignited, including the quality of the spark plug itself, the failure of the igniter, the failure of the high-voltage pack, the failure of the magneto coil, the failure of the ignition switch lock, the poor contact between the ignition wire and the generator, and the loss of magnetism of the generator flywheel magnet1. The most common causes are the quality of the spark plug itself, faulty igniters and faulty high-pressure packs. If you encounter this situation, you need to check whether the above parts are normal and replace or repair them in time.

The spark plug is the terminal of the ignition circuit. Ignition coil, trigger, ignition control unit (including electric door lock, flame-off switch), high voltage pack, high voltage cap and finally spark plug. If the spark plug is not ignited, there may be problems in each of the above places, and they should be investigated one by one.

Eliminate the spark plug first, and aim the ignition high-voltage wire directly at the cylinder block or sell the heat sink, if there is a fire, it is a spark plug problem. If there is no fire, check the high-voltage pack inlet line (the input line from the ignition controller to the high-voltage pack) with a multimeter, and if there is no voltage or the voltage is too low, check the ignition front-end voltage (igniter power line and pulse signaling line). If there is no voltage in the power line and pulse signal line or the voltage is too low, the generator part is faulty.

Usually the wire is broken or the trigger is damaged. The coil and magneto are generally not easy to be damaged, and the most likely to break the ignition line of the dipstick is the high-voltage bag and igniter. Of course, any one place, including short circuits and open circuits of wires, is possible.
