The ignition coil of the trimmer for the grass. malfunctions and repair

Motokosi is a popular seasonal tool designed to remove unnecessary vegetation in the house site. Like any other technique, these devices periodically break. Repair of a he ignition coil of a trimmer for grass is one of the popular problems characteristic of gasoline cos. The ignition system itself is designed similarly on two- and four-stroke ICE, so the elimination of the breakdown is carried out almost the same for the tools of different. Huter, Husqvarna or other brand. Ways to restore the performance of the ignition coil or replacing it with a new one. in the material further.

The purpose of the ignition coil is the conversion of rotation energy into a high.voltage discharge and the formation of a spark that ignites the fuel mixture. In the internal combustion engine, this part is called magneto, since in it alternating current is generated from rotation of a constant magnetic rotor or anchor.

Magneto constructively consists of two windings: high and low voltage. The condenser with interrupter contacts are parallel to the latter. Whereas the conclusions of the high.voltage winding are connected to the candle and body. They are both wound on a core between the poles of which a rotating magnet is installed, magnetized longitudinally.

On a note! The whole structure looks like a large coil installed on the P-shaped core.

How the ignition system operates on the trimmer

The ignition system of a two-stroke ICE consists of 2 elements: flywheel and coils (magneto). The figure below shows how they look.

There is a impeller on the flywheel, which works like a engine cooling fan. There are also permanent magnets on one side of the flywheel, the figure is shown by the arrow.

When the flywheel rotates in the coil, an electric current is produced, which serves for a spark on the spark plug. The spark appears at the moment when the magnets are directly under the magneto.

The main problems and malfunctions of the carburetor.

Mesh filter. Only two obstacles often arise with this element:

In order to find out the cause of the breakdown, unscrew the fuel filter lid to remove the strainer. If dirt simply accumulates on it, then rinsing with gasoline or purging will help.

If there is a visible damage to the strain, you must definitely install a new. Fuel supply pipes can also be damaged (during repair, they practice checking this element).

Carburetor starter in most cases does not work as a carcass. For washing, use acetone or the same gasoline.

Blowing parts of a carburetor with clogging compressed air is acceptable and convenient repair practice.

The housing of the throttle, the location of the parts of the carburetor, the intake or output pipeline, all these parts are subject to depressurization. Perhaps you can check the problem area in a simple way with soap foam.

Setting the ignition system.

In most modern models of chainsaws and trimmers, it is not required to set the angle of the ignition. This angle is determined by the position of a special groove on the flywheel for the binding attachment to the crankshaft and the magnets installed on the same flywheel.

It is only necessary to properly set the gap between the flywheel and the ignition coil. How the ignition system works on the chainsaw, what is the advance angle. How to set the ignition on a chainsaw: an algorithm for checking and adjusting. Depending on the model of the tool, the size of the gap can be of different. It usually is 0.2-0.4 mm.

Since the flywheel is round, the usual car probe for these purposes will not work. It would be technically competent to set a gap on a special template. How to set a ignition on a chainsaw? I ignition setting technique for setting up installation. But it is not always possible to purchase it. How to set a ignition on a stihl chainsaw.

Buying such an expensive template for one.time use is unreasonable. Instead of a company template, you can use a strip from a plastic bottle of water. How to adjust the tension of the chain on the chainsaw for elasticity the circuit, how to correctly. Cut a strip from a bottle in a place where there is no embossed embossing.

Further, the actions for the exhibition of Zazaor are approximately the same for both chainsaws and for trimmers:

  • Loosen the ignition fastening bolts.
  • Suppry the magnets on the flywheel to the ignition coil
  • Clutching between the flywheel and the coil of the plate from under the bottle, tighten the fasteners.
  • Remove the strip
  • Scroll the flywheel 360 degrees several times, monitoring that he does not cling to the coil anywhere.

All. The gap between the coil and the flywheel is exhibited.

The repair of the ignition coil is impossible and impractical. The following is a list of ignition coils that can be bought on our website

Backing

Each fisherman must know how to wind a fishing line for a trimmer for a trimmer for grass and what is backing. Backing is a winding on the roller’s ropes. To do this, often use a thread with a diameter of 0.1 to 0.3 mm. If you use a thicker fluorocarbon as a winding, this can lead to uneven and uneven laying of the main fishing line. It is extremely undesirable for backing to use wet materials, this include nylon and cotton threads. They are unable to dry for a long time, which leads to a debate, and replacing the fishing line on the trimmer. These are additional financial costs.

The amount of thread required for backing can only be determined experimentally. This will require two spools. The required amount of the working fishing line is first wound on one, and then the backing is wound so that two millimeters remain to the edges of the side. After this procedure, a spool with wound fluorocarbon is removed and worn empty, on which the thread is wound, only in the reverse order. first backing, then a nylon worker.

How to set a ignition on a trimmer

Often, owners of gasoline cos are faced with the fact that ignition does not work on their technique. In most cases, the problem is really in this node. To fix it, you need to adjust the ignition on the trimmer. But at the same time, there are frequent cases that the ignition coil is working and a breakdown should be sought elsewhere. The ignition system is arranged equally on four.stroke and two.stroke internal combustion engines, therefore, the correction of the malfunctions of this node is carried out in a similar way. In addition, the technique of different brands has an almost identical design of this most important component of the tool, which means that the process of adjustment will be identical for both the trimmers “Soyuz” or “Prostr”, and for Huter or samples of other brands.

Why the lawn mower is not started? Diagnosis of trimmer faults for grass

In this video clip, we will try to make out the main malfunctions that occur during the operation of the motorcycle.

After several jerks, he will start and stall, which is a common occurrence. Putting the damper to the working position, start the tool again and start working.

There are not only situations when trimmers for grass gasoline

do not start, but cases when after starting they work for a couple of seconds and they stall here. Inspect the spark plug again: if it is “thrown”, while this situation is repeated even after wiping it and drying, run to the “audit” of the air filter.

Most likely, he is quite naked and needs to be replaced. If everything is fine with the filter, it may be so that the ignition coil has failed.

In the case when trimmers for grass are gasoline

do not start, but you have done all of the above, maybe the muffler may be clogged. It must be dismantled, burned on a burner, after which the whole fog can just be shaken out.

And again the carburetor.

Well, even if after such bullying your trimmer does not start for the grass, you can’t do without disassembling the carburetor for you. It may well be that everything is guilty in the needle in it. In any case, the disassembly and washing of this capricious mechanism certainly will not hurt. Adjustment of the lawn mower carburetor can be adjusted with your own hands, like the entire benzo tool for the garden, is not difficult to maintain equipment. Repair, configure without the help of others you can and necessary. For example, adjusting the carburetor of the lawn mower with your own hands. it is 5 minutes. The carburetor from the lawn mower is a node in the power supply system. Idle…

Many trimmers’ owners are faced with inconsistency when the device simply does not start.

One of the circumstances of this may be the lack of a spark

This usually happens when the fuel floods the light of the ignition. In addition, you need to check the candles for serviceability, as this can also lead to a lack of spark.

The first sign of a faulty candle is the presence of a short circuit between its contacts, and in short. there is no spark on the trimmer.

ignition, correctly, device, chainsaw

In addition, the candle is considered faulty if it is covered with a black wet layer.

Such a layer appears from the oil combustion chamber. In such a situation, you have two exits: either clean the candle as it should, or buy a new.

Diagnosis of magneto

Magneto. key node in engine ignition systems. This is a reel with a core, which is surrounded by primary and then secondary windings. If this part is faulty, there is no spark on the spark plug, and the fuel does not ignite.

The first way

You can check the work capacity of the magneto using a tester. To do this, you need to perform such a sequence of actions.

  • Correct the tester correctly: use the resistance measurement function and set 200 Ohms to remove the measurements of the primary winding.
  • The first electrode of the measuring device is sent to the “mass” of magneto, and the second to the output contact. If the primary winding is working, the indicators should be from 0.4 to 2 Ohms.
  • Install the tester switch by 20 kOhm to diagnose the secondary winding. Then send the first probe to the cap of candles, and the second. to the “mass”. If everything is in order, the indicators will vary from 4 to 6 kOhm, depending on the model of the trimmer for the grass, whether it is Patriot 547, Husquarna 128 R or a technique of another brand. If the chain is cut off, the infinity value appears on the tester screen. And if there is a short circuit, zero will be displayed on the display.

The second method

If you use the tester, there is no other way to check. At the same time, it is important not to touch the cylinder electrode, otherwise the coil will be damaged.

  • It is necessary to remove the cap from the spark plug. You should not unscrew the candle, as this will save compression.
  • Then you need to choose a nail with a remote hat and tightly insert it into the cap.
  • Further, the cap with a nail should be reliably tied to the cylinder by the dielectric. In this case, the electrode should be at a distance of 5.5-7 mm from the cylinder body, but do not touch the mass.
  • Then the starter needs to simulate the start of the motor with the ignition button. In this case, it is required to carefully monitor whether the spark will appear, and try to determine its color.

Important! A strong spark of white or with a blue shade indicates in favor of the serviceability of magneto. If it is weak, as well as orange or yellow, magneto is damaged.

There is one important point that needs to be taken into account when diagnostics: uninhabited magneto in any state can form a powerful spark. However, if it is faulty, then, heated, stops creating a current, and the trimmer does not start for the grass. Later, cooing, the coil again returns to the working level, the unoic tractor turns on and for some time works at idle or under load, until the magneto temperature rises again. In this case, the part needs to be changed for a new.

On a note! In a number of situations, the problem with heating does not occur due to the fault of the coil, but due to the spark plug. This means that the test must be subjected to both parts.

The spring may interfere

My first attempt to adjust the gas mowing carburetor did not give anything, since the spring of the fuel mixture adjustment propeller prevented. The factory spring turned out to be too thick in a compressed state and did not make it possible to reduce the supply of fuel to the required level. I had to choose another spring and continue the adjustment after its replacement.

Settling of the ignition on the trimmer. How to set a ignition on a benzoca

On gasoline trimmers, both two.stroke internal combustion engines (ICE) and four.stroke. But the ignition system there is no different from each other, so the repair and configuration of this complex of accounting programs for ignition of fuel will be identical to different types of internal combustion engine.

The ignition system of a two-stroke ICE consists of 2 parts: flywheel and coils (magneto). The figure below shows how they look.

There is a impeller on the flywheel, which works like a fan for cooling a motor. There are also permanent magnets on one side of the flywheel, the figure is shown by the arrow.

When the flywheel rotates in the coil, an electric current is produced, which serves for a spark on the spark plug. The spark appears at the moment when the magnets are directly under the magneto.

From time to time when the engine does not start, the ignition adjustment will be necessary. Naturally, first you need to check the serviceability of a candle and a high.voltage cable with a cap.

It is necessary to adjust the ignition on a two.stroke engine to ensure timely ignition of fuel in the combustion chamber of the motor. Below is a scheme, you can understand the principle of operation of the internal combustion engine.

The spark in the candle should appear at the time of compression of the fuel piston, when it does not reach the top of the upper dead point (VMT) more than the best. When the piston passes through the VMT, the fuel mixture is ignited, under the influence of which the piston goes down under the action of the energy of the explosion.

If for at least any reasons (to a greater extent this is due to the shift of the flywheel to the shaft relative to its starting position), the fire of fuel occurs earlier than the piston passes, then it will come back, and the crankshaft scrolls in the opposite direction. Such a movement can damage the starter knot, cut off the launch cord, etc.D. Then there is an early ignition of fuel.

Also, you will like a later ignition on the trimmer more for you: the piston after compressing the fuel, which did not ignite, goes down, and in this case there is a spark. Then the engine will either not be launched or significantly lose power and will be poorly gaining momentum.

But such tasks with early or late ignition on two.stroke ICE are quite found from time to time, because the flywheel with magnets is already established in the correct position, which is completely synchronized with the movement of the piston. In addition, the flywheel is fixed on the shaft using a key and nut. Therefore, the wrong installation of the part is excluded.

For the most part, the ignition adjustment is to set the correct gap between the magneto and the flywheel.

Magneto is the main detail in the ignition system of the motor and is a coil with primary and secondary windings located around the core. Often, due to the malfunction of the magneto, the spark on the spark plug disappears, and the fuel ignition does not occur. To check the coil, it will be necessary to use the tester, and fulfill the following acts.

  • On the tester, going into the resistance measurement mode, you need to set 200 Ohms. In this way, the primary winding will be checked.
  • Connect one tester electrode to the “mass” of the coil, and the 2nd-to the contact emerging from the magneto. Normally, the resistance will be from 0.4 to 2.7 Ohm.
  • To check the secondary winding, it will be necessary to install the device switch by 20 kOhm. Further, one probe of the device is inserted into the cap of the candle, and the 2nd-is connected to the “mass”. Normally, the properties of resistance should be in the range from 4-6 kOhm and above (depending on the model).

When a circuit is broken, the device will show infinity, and when close. 0 (zero).

The first way

You can check the work capacity of the magneto using a tester. To do this, you need to perform such a sequence of actions.

  • True tester: use the resistance measurement function and set 200 Ohms to remove measurements of the primary winding.
  • The 1st electrode of the measuring device is put on the “mass” of the magneto, and the 2nd-to the output contact. If the primary winding is working, the characteristics should be from 0.4 to 2 Ohms.
  • Install the tester switch by 20 kOhm to diagnose the secondary winding. Then bring the 1st probe into the cap of candles, and the 2nd-to the “mass”. If everything is in order, the characteristics will diversify from 4 to 6 kOhm, depending on the model of the trimmer for the grass, whether it is Patriot 547, Husquarna 128 R or a technique of another brand. If the chain is cut off, the infinity value appears on the tester display. And if there is a short circuit, zero will be displayed on the screen.

If they are not confident in their abilities, or do not agree with the warranty conditions, then the request to refrain from buying.

System of contactless electronic ignition ants, Tula.

The optimal solution for high.quality engine operation is the use of the so.called contactless electronic ignition systems (BESZ).

The most important advantage of the contactless ignition system, compared with the contact, is the supply of much greater energy to the spark plug, which significantly increases the spark so necessary for combustion of fuel. Thus, the combustion of the fuel mixture improves, which affects the engine power.

No less important is the fact that the shape and stability of impulses in all range of engine operation improves significantly. This is achieved by the fact that instead of the contact system of the ignition, an optical sensor is used, which is needed to form the control pulses to the electronic switch. Thus, not only the power and acceptance of the engine improves, but also the fuel consumption is reduced.

The third advantage and advantage of the contactless ignition system is its unpretentiousness and low need for maintenance. It must be configured once and that’s it. While the contact system is demanding on maintenance and configuration.

Prevention of problems

The ignition coil failures are often associated with a short or open winding and mechanical damage to the magnetic case. This is due to strong blows, liquid and oxidation, as well as overheating. If you avoid such cases, you do not need to worry about the integrity of the ignition coil.

One of the components of Magneto, which regularly suffers during use, is high.voltage wires, along which the current is supplied to the spark plugs from the ignition module. They have a long service life, but users themselves harm them due to irrational behavior when replacing the spark plugs, unintentively pulling the wire, and not the tip. Another problem that can happen to them. It is moisture, oxidation or insulation damage. These problems can be avoided by gently removed the spark plug and avoiding liquid entering the device.

Therefore, the repair of the ignition coil is not very complicated and can be performed by the user himself, but subject to the above procedure for disassembling and replacing the magnet or contacts of the switch.

How to install Magneto on a scooter ant and whether it is necessary?

Ant is a universal scooter that is used by rural and urban residents as a means of transportation, truck and even tractor. Each owner of the ant sooner or later thinks over the installation of a magneto or a contactless ignition. details, why put Magneto on an ant and how to fulfill this task, you can find out from this material.

Before putting and setting Magneto on a scooter, think about whether there is a sense? The device will not solve the problem with the ignition system on the motorcycle, in fact the owner of the vehicle will encounter other troubles.

  • After installing and adjusting the magneto, motorcycle owners are faced with the problem of wear of the rubber coupling. It is constantly strayed, as a result of which the ignition is also lost. And this leads to the appearance of detonation, a decrease in engine power, its overheating. As a result of installation, you can encounter increased fuel consumption.
  • After the installation of Magneto, the owners of the scooters cease to monitor the operability of the dynostarter, believing that this no longer needs to be done. If the dynostarter will work without a battery, this will lead to its inoperability, as a result, the electrical scooter is left without power. What operation of the vehicle can be discussed if there is no voltage source in it?
  • It should be borne in mind that alteration of this kind will contribute to the fact that the axes in which the rotors of the dystarter and magneto rotate will diverge within large. Ultimately, the elements of these nodes will function with axial distortion, and this will lead to a regular break in the output shaft of the rotor. The same problem can cause accelerated wear of bearing devices.
  • Before installing Magneto, keep in mind that the node is not designed for long.term operation, if we are talking about the functioning in the conditions of the axis distortion. As a result of distortion, the radial load on the rotary part will be a higher.
  • Another nuance is that the cost of Magneto is not low today, so not everyone can afford such a “luxury”.

Magneto installation manual

If you decide to install Magneto, then we cannot dissuade you from this.

Detailed installation instructions are presented below:

This can be done on top of the fans. Fix the coupling on the rotor using four secret bolts, this is one of the reliable options and is preferable than the use of traditional screws.

  • Dismate the protective grill located in the cooling snail. It can be broken.
  • Having performed these actions, you will need to leve this snail from the inside. It is required to trim it so that a spacer can enter it, for this use a round file.
  • Install the spacer in a snail. On the eyes to fix the element, apply marks for future holes.
  • When all the holes are marked, drill them using a drill.

In the holes, you need to cut the thread so that you can tighten M6 bolts.

Setting the ignition system.

In most modern models of chainsaws and trimmers, it is not required to set the angle of the ignition. This angle is determined by the position of a special groove on the flywheel for the binding attachment to the crankshaft and the magnets installed on the same flywheel.

It is only necessary to properly set the gap between the flywheel and the ignition coil. How the ignition system works on the chainsaw, what is the advance angle. How to set the ignition on a chainsaw: an algorithm for checking and adjusting. Depending on the model of the tool, the size of the gap can be of different. It usually is 0.2-0.4 mm.

Since the flywheel is round, the usual car probe for these purposes will not work. It would be technically competent to set a gap on a special template. How to set a ignition on a chainsaw? I ignition setting technique for setting up installation. But it is not always possible to purchase it. How to set a ignition on a stihl chainsaw.

Buying such an expensive template for one.time use is unreasonable. Instead of a company template, you can use a strip from a plastic bottle of water. How to adjust the tension of the chain on the chainsaw for elasticity the circuit, how to correctly. Cut a strip from a bottle in a place where there is no embossed embossing.

Further, the actions for the exhibition of Zazaor are approximately the same for both chainsaws and for trimmers:

  • Loosen the ignition fastening bolts.
  • Suppry the magnets on the flywheel to the ignition coil
  • Clutching between the flywheel and the coil of the plate from under the bottle, tighten the fasteners.
  • Remove the strip
  • Scroll the flywheel 360 degrees several times, monitoring that he does not cling to the coil anywhere.

All. The gap between the coil and the flywheel is exhibited.

The repair of the ignition coil is impossible and impractical. The following is a list of ignition coils that can be bought on our website

When you need adjustment

It is necessary to adjust the ignition system so that the fuel is ignited at the right time in the combustion chamber.

Important! Когда поршень сжимает горючее и практически достигает мертвой точки сверху, в свече возникает искра. Further, when it passes the maximum upper point, the fuel is lit up, as a result of the explosion, energy forms and directs the piston down.

If the flywheel is shifted to the shaft relative to its original position, the fuel is ignited faster than the piston overcomes the upper dead point. As a result of this, the piston moves back, and the crankshaft rotates in the opposite direction. You can determine the early fire of the fuel by a broken launch cord, a broken starter node or other breakdowns.

Sometimes ignition is late. The piston compresses the irreparable fuel, and then goes down, and only then the spark forms. As a result, the engine either does not work or its power is reduced, and the speed is gaining much slower.

Typically, a flywheel with magnets is installed in an ideal position, as if coordinated with the operation of the piston, and in order to avoid displacement, it is carefully fixed. This allows us to say that an incorrect installation of a part is impossible. But if the shift of the flywheel is a confirmed fact, then it is a failure or accident. Thus, the installation of the moment of the ignition is not required, since problems with early or late ignition of fuel happen very rarely.

Important! It is very simple to regulate the ignition system. There is no need to calculate the ignition angle angle. The maximum that you need to do is to properly set the gap between the flywheel and the reel.
