Video 53 Dạy sửa xe: Phần 4 Mạch Xi Nhan, Mạch Khởi Động Và Các Bệnh Cơ Bản | Motorcycles TV

Hello everyone who is watching MOTO CYCLE TV Today I will continue the electric guide This is the 4th video clip of MOTO CYCLE TV For those who are passionate about motorcycles and want to know more about the field of motorbike repair I will continue the video clip series about the guidance of the three diseases in the electric system of motorbikes In this series, I will go from low to high In videos 1, 2 and 3, I have shown you the basics such as measuring electric clock, wire color And the function of some basic relays such as charging, IC, fire, etc. I have also talked about the first class Now I will go deeper into each circuit Today I will make two circuits The first circuit is the RELAY SIGNAL circuit And the second circuit is the starting circuit of the motorbike Why do I make this series of motorbike repair? There is a deep reason During my time as a motorbike repairman And there are some jobs related to motorbike repair in Vietnam I realized that my colleagues are very good at motorbike repair But they are not very good at motorbike repair Because they are not specialized in electrical engineering They are trained to understand the principles of electrical engineering In the past, I studied electrical engineering I have a passion for automotive mechanics But I didn't pass the exam So I had to learn the second desire, which is electrical engineering Based on my passion for motorbikes I went deeper into the electrical system of motorbikes and motorcycles In the series of motorbike repair, I will continue But after that, I will teach my colleagues about electrical engineering That's the introduction of today's video I would like to remind everyone Currently, Motorcycle TV only uses this YouTube channel To communicate with motorcyclists Share experiences about motorbikes In the future, I will also set up Facebook, Fanpage and Yalo About Motorcycle TV I hope you will support and accompany me In order to bring videos about motorbike repair To the motorbike lovers As well as help some motorcyclists and enthusiasts Get closer to this profession As well as this hobby That's the introduction of today's video Today I will make a clip Talk about the activities of Rele Sinyan and Rele De Don't think that this electric circuit is simple I hope you will watch this video from beginning to end To understand some of the electric circuits As well as the fastest operation to check the circuit Don't have to spend a lot of time I will introduce the circuit to you And then I will go deeper I will guide you to determine the cause of the circuit To understand the circuit Now I will talk about the topic today As you can see on the screen This is the operation of a Rele Sinyan I will simulate a battery and a Sinyan terminal I call it Sinyan terminal Or call it Rele Sinyan Battery and light system I skip the switch system I talk directly to this Rele As you can see When there is an electric current for Rele When I put out a light bulb It will light up slowly I put on a light bulb larger than the previous one This Rele Sinyan will light up faster The signal will be faster You see It will light up faster When I remove the light bulb This Rele will stand This is the Rele Sinyan Jim For Rele Low When a light bulb is lost, it is still bright For Rele Jim When a light bulb is lost, it is still bright Why do we say this This may be due to the fault of the manufacturer And it is very impossible to fix this problem To cover these details Let's talk about the main issue Don't worry, when you go to this power supply chain, you will go straight to FE, BGMF2 I will go straight to I-LINK STOVE and even go to ABS I will guide you from low to high, to the sensors So I have all the power supplies For example, I have ECM, IC, power cables, etc I have everything I need to guide you So don't worry, I have a lot of things to show you So it will be easier for you to understand About the signal As you can see, I have drawn a diagram In the previous clip, I also talked about this diagram This is the signal of Honda and Yamaha For Honda, the battery will be connected to two red and green wires The red wire will go straight to the lock When you close the lock, the signal from the battery will be transmitted to the black wire The black wire will be connected to the relay This is the relay This relay has a black wire and a gray wire This is the relay of Honda The gray wire will be connected to the signal switch In this switch, there are three pins The first pin is gray, the second is orange, and the third is blue The orange pin is on the left, and the blue pin is on the right There is a funny saying to help you remember the Honda's signal The orange pin is on the right, the blue pin is on the left Remember that sentence, you will remember the Honda's signal The electric current will go from the red wire to the black wire The black wire will be connected to the relay When you turn the switch to the left, the gray wire will be connected to the orange wire The orange wire will be connected to the black wire The orange wire will be connected to the relay For the jeans on the car, when we remove a light bulb, it may not light up It means that the relay does not light up Or even when we attach a LED light bulb, the relay does not light up Because it is a mechanical relay If we want to use a LED light bulb, we have to switch to an electronic relay To understand the electric current of the wires and the electric current of the LED light bulb I will talk about some of the bands For example, there is a car coming to the store or at home The car is turned on and off, but the light does not light up First, you have to check First, I will use a VOM meter I will set the meter to 12V 1A My watch is 20V 1A And I will measure the electric current for the black wire And the voltage of the battery is 12V If this wire does not have a 12V signal It means that the signal from the lock of this relay is broken Or the car is broken For some cars with a signal system I have to check First, if all the signals are off Then I have to check the input of the relay If this input has a signal Then I will check the output signal With a 12V meter You can also measure But this is because it uses a circuit in this It controls the electric current It changes the current If you use a measuring watch, it will be more difficult So I will use a test light I have the equipment to repair the electric car I need a tail light I need to prepare 2 items First is a magnet Second is a tail light like this Let me try the signals I will put one end of the tail light in the gray area And the other end of the tail light in the negative area If I try the tail light here The tail light shines It means that this relay has a power signal Then I will continue to check the power system If you try here The tail light shines Don't rush to conclude that this relay is broken For the relay machine, if you try with one tail light I'm not sure if it works Because the current of a tail light is not enough So that the relay and the inside can understand Understand that it has to turn off So you need 2 or 3 tail lights When you check the gray area I will check the switch I check the middle of the switch Does it have a power signal? If it has a power signal It means that these 2 legs are not connected If these 2 legs have a power signal It means that these 2 lights have to shine Why? If I assume that this tail light is broken It will not shine But the clock light will shine And the right tail light will shine Because if the tail light is broken, it will only be broken on one side If you are logical I will check the circuit If I turn on the signal Signal on the right side Good signal No signal on the left side Then it is broken in this switch This switch is not powered Or this orange signal cable is broken Then I will check the signal line on this side If you turn on the switch on the left side Bright enough The switch on the right side is bright enough But the clock light is not bright So there is a problem with the signal to this clock Then I will check the clock light That is the elimination method And if these 2 lights are bright But the 2 clock lights are not Then the matrix inside the clock is out of signal So the clock light is not bright And if you see the clock light is bright The tail light is bright But the front light is not bright Then maybe the 2 front lights are not bright Then it is out of matrix Because usually the lights like the clock It will use the same matrix The front tail light will use the same matrix The tail tail light will use the same matrix So if you notice Both tail lights are not bright But the tail light is standing It means that the front tail light is standing It is not dead But the tail tail light has no signal It is not bright Then I conclude If the left side is not Then there is a problem with the left side And if both sides are broken Then I conclude that the matrix is broken You guys imagine I explain on the schedule It is like that For the Yamaha fast It will be different in the color of the wire The Yamaha car The matrix of it is no longer green But it is black The signal cable from it is still red But the cable behind the lock is brown And the cable behind this relay Instead of gray like Honda It is white brown In addition, the left signal of it The left side is brown Almost the same as the brown cable behind the lock And the right side is dark green The principle of operation is the same as the Honda signal This is the signal Now I give an example for you to see I give an example for you to see the signal When I attach a relay I attach a relay The black leg is in the frame Then I put the gray leg Put it through the switch Then the switch turns on the signal light If there is only one light The light behind is broken Or the light behind is broken Then it is not dead Not sure if this relay is broken To decide if it is broken or not I will insert another light To show you clearly I will insert a second light Here This is a second light I will use one leg to attach to the mat The other leg attaches to the lamp Then I also have a third light I will use the third lamp Let me show you how it changes the sound. Two light bulbs. I put the gray one in. I connect the power source to the relay. Can you see how it changes the sound? If the signal is here, the light bulb is blinking. If this light bulb is blinking, it means it's on. If this light bulb is on, the two light bulbs change the sound. If there is a light bulb number 3, it will change the sound faster. The electric signal will work faster. If there is no electric signal, the light bulb will not work. In the future, I will try to make it on the board. So that my brothers can observe more clearly. If I do it by hand, I don't have a switch to hold it. Sometimes it's a bit loose. Now I will adjust the light bulb. I will adjust the light bulb of the light bulb number 3. This light bulb has a problem. The light bulb is broken. I will put a light bulb number 3 in here. The light bulb number 3 is here. I connect the power source to the relay. I connect the power source to all three light bulbs. The light bulb is if it is broken. Now I connect the power source to all three light bulbs. The regular one is not enough to connect. This red light is the phone's lightsaber. When I change the light bulb. If I change the signal light back, it will be brighter Now I will put the clock light on I will try to put the clock light on It will blink slowly The two light will blink slowly It will blink very slowly When I put the clock light on It will blink faster Can you see it? So I have talked about the signal light From now on you can use your brain To find out how the broken signal light works You can figure it out Next I will talk about the relay light The relay light In the last lecture It has many applications It can be used in a lot of applications, such as turning off the machine, turning on the lights, and so on. People can use this relay to connect a xenon light bulb, or people can use this relay to connect a led light bulb. That's normal if you need to charge a lot of electricity. This is the structure of a relay. I drew it on the map. As I told you before, a relay has 4 legs. The 2 main legs are for receiving signals from the battery. The 2nd leg is for the device. Why do people use this 4-legged relay? For devices that consume a lot of electricity, such as xenon lights and motor devices, when we use it, it will generate a lot of current. So if we use it directly, it will easily heat up the wires. That's why most of the wires that come to the device are large cables. In this relay, these 2 cables are always big. The hole is very big. It's much bigger than these 2 signal cables. These 2 cables are a red cable. This red cable is for the battery. The white red cable is for the motor device. These 2 red cables are always charged. The white red cable is not charged. In this relay, there is always a cool source. It's always cool. The wires are always cool. Or it's always connected to the signal. But most people will always let it cool down. Why? If the wires are always connected to the signal, it's like a long light bulb at home. If we have a cold switch, and we put a hot wire directly into the light bulb, the electricity will be reduced. So no one does the job of connecting a hot wire to the wire of this relay. Because when you do that, it will reduce the age of this relay. So people will always let this relay cool down. And the signal will be separated by the switch. The switch is controlled by the red wire to the switch. The switch will connect the signal to the black wire. For the Yamaha motor, the signal is to the brown wire. And then this electricity signal, when it passes through the switch, it will go to the yellow-red wire. This yellow-red wire sends a square signal to the wire inside the relay. Helps keep this relay cool. When the switch is closed, the motor is always connected to the motor frame. The motor will rotate. And when the switch is released, the motor will lose the signal. Because the wire stops working, and the switch returns to its original position. So now, for this relay, how do I do it? Before going into the details of the relay, let me go through this document. I will show you the operation of the relay. Now, let's assume this is the motor relay. This is the motor relay. It has a swing and a swing. The swing is the orange wire. The swing is the blue wire. The swing signal is taken from the red-white wire. I take it from the red-white wire. The swing signal is connected directly to the motor frame. On this relay, there is a black wire. I will connect it to this green wire. I send a signal to it, to the motor frame. To the motor frame. I send a signal to the motor frame. Then, the swing signal will be taken directly from the motor frame. That means it always has a swing signal to the relay. That's why this relay is usually placed near the motor frame. This relay is always near the motor frame. The position is like this. Then, when the switch is connected to the motor frame, the light will be on. The light will be on, right? Now, let's try to use a broken relay. This is the inside of the relay. Actually, this is the four-legged relay. Let's open the relay. It looks like this. This is the inside. There is a metal clip inside the rubber. It is actually the four-legged relay. Can you see it? It's just a four-legged relay. This is a broken relay. Let's open it. Now, let's try to plug in the broken relay. Come here. Let's plug in the broken relay. Okay. Let's plug in the broken relay. When I plug in the power, the light is not on. The relay is not closed. That means the wire inside the four-legged relay is broken. Okay. Here, I also have another type of relay, which is a circular relay. For the old generation of I will show you an example. It works like this. These two main poles are directly connected. I will connect the signal of the circuit of the device directly to this pole. Okay. This is the signal of the device. The signal of the circuit of the four-legged relay. I will connect it to the device. I will plug it into the battery. Okay. This is the signal of the circuit. The yellow wire is the signal of the circuit. I will find a short-circuit wire. I have a short-circuit wire. This is the signal of the circuit. The signal of the circuit of the relay. Right? The signal of the circuit of the relay is connected to the battery. It's connected. The yellow wire will get a pole of the relay. Okay. The rest of the wires will be directly connected to the battery. But in order for this relay to work, the signal receiving pin has to receive the signal Can you hear it? But because it doesn't have a power supply here, the light is not bright enough Let me show you It's receiving the signal It's receiving the signal but it's not bright enough What does it mean? Even though this relay is still working, but the two contacts inside this relay are oxidized So it can't communicate This relay is also damaged We don't use a VOM watch to determine if this relay is alive or dead For example, let's measure the voltage I'm measuring the voltage I'm going to measure the voltage of the cable This signal cable is 168.9 ohms Now I'm going to measure the signal of this round relay This round relay is the damaged relay I'm measuring the signal of the cable There's almost no signal So this round relay is damaged But I don't know how it's damaged When I tested it, there was still a sound of electricity jumping inside the relay I have to know the cause of the sound of the relay so I can measure the voltage It's still jumping But when I measure the voltage, there's no voltage value So this relay is also a damaged relay In such a complicated situation, the relay still jumps I don't know why the relay is damaged So what should I do? To fix the problem when the motorcycle is out of order I have to press the stop button The motorcycle can't stop, the motor won't start In high-end motorcycles, the motor will start from this side For example, this cable will go through the stop button And the motorcycle will go through the stop button It will start from this side Let's talk about the motorcycle When you can't stop the motorcycle First, you have to check if the relay is jumping When you press the stop button, you can hear the sound of the relay Is it jammed? It's jammed like this For example, I put a good relay in The signal is jammed, it sounds very clear It sounds like this For example, I press the stop button, but I can hear the sound of the relay It means that the signal from the stop button to the relay is jammed So why is the motor not running? Then you have to decide You will use a small pliers to pierce these two legs Or you can use a stick or something But don't touch it Because the electric current goes through the relay If you touch it directly, it will be pierced So you will stick these two legs See if the stop button is running If you stick these two legs in, the stop button will run So the decision is to damage this relay If you press the stop button, but there is no signal Then you have to check if the relay is jammed Is the signal from the stop button to the relay jammed? Is the stop button running? If you hear the sound of the stop button We will connect these two legs directly to see if the stop button is running You can use a small pliers to pierce these two legs Or you can use a stick But don't touch it Because the wire is very hot It is easy to burn your fingers When you pierce it like this, the stop button will run The stop button will run means that this relay is damaged Then you just have to replace the stop button If you pierce it directly like this There is power to the stop button But the stop button does not run So the first reason is that the wire to the stop button may be broken It is jammed I will measure and see if the signal from the stop button to the stop button is clear If it is still clear, then I conclude that the stop button is out of power Then I will replace the stop button or the stop button is burned Those are some of the problems in today's video clip I want to send to you Today's video clip is mainly about measuring the transmission Actually, the value of these relays is nothing to measure Mainly, we measure the transmission of the wire In the next video clip I will talk about the charging system of the motorbike Basic charging as well as high-voltage charging Charging of Honda This is the charging of Honda Green tail charging Green tail charging is the charging signal of the 1-phase bridge Green tail charging is the charging signal of Yamaha 1-phase bridge charging is the charging signal of Honda I still know by 2 chargers I know it by Honda and Yamaha 2-phase bridge charging is the charging signal of the old Atilla 2-phase bridge charging is the charging signal of the new Atilla SWM New Yamaha or Exciter Some motorbikes use 3-phase bridge charging I will talk about measuring the charging signals I will guide you on charging For those of you who are really passionate I should look up this topic Because this is the first step, just like when we are sick, when we know how to prevent the disease, for example, we cough, why do we cough? We can tell the doctor, because yesterday I ate hot food, or I drank a lot of ice water, I coughed. The doctor knows the cause, they will find the correct treatment. When we understand this principle, we know exactly the disease, then we can contribute to the hospital, help them fix the car faster, or we take care of the operating principle, then we will solve the problem of the car disease faster. For example, you understand, you solve that problem in 5 minutes, and those who don't understand, just keep on coughing, coughing, that line of coughing, sometimes it takes a whole day, but instead of having a taxi, you only have 35,000, 30,000, or 50,000, fix it in a whole day, it's a pity for your job. Actually, I really advise you, if you are really passionate about your job, you should spend time to learn to improve, learn more, for example, painting, I know a little, electricity, I also know the basics, engine, convenience, wiring, the type of goods I cut, I should know, so that if the convenience store is closed, or something has a problem, then I can also interfere with the problems quickly and quickly, to make my job more convenient. As for if you are really passionate about your job, you should invest in it a little, but if you are conservative, I can do it, then I don't teach, then I only advise sincerely, if you are a teacher, you should temporarily learn, learn online is fine, learn online, apply is fine, should learn, learn knowledge, so that I can improve my job. Today's video clip, I only have a few problems, so I hope you will continue to follow this chain of electricity, because you don't have to comment that I guide, guide the super high, such as Islington, APS, because I will go in order, from low to high, and I also have clips, when I hit the road with some cars, I will also film, I will post it for you, but I advise you to go in this order, hold the basics, when it comes to higher levels, I will understand, and now I will go in, review the last time I went in, about the ICFE, I just said it simply, the IC of the old Clip Airblade, 22 feet, this IC is 22 feet, now I suddenly review the last time I went in, I said about this IC, for sure some basic people don't understand, or the IC of Exciter, this Exciter has 12 feet, you see, 12 feet, now I review the last time I went in, I said about this IC, I gave up, so I will go basic, so please sympathize, if you know, I will refer to fun, then what I am wrong, you can comment below, contribute your opinion, so that in the new clips, I can correct, I update directly, for those who are passionate, people understand, we share experiences, and those who do not know, I will find out more, thank you for always accompanying, and support Motorcycle TV, see you in the next clip, because now I have a job, I will update this video regularly, maybe a few videos a week, for you to update continuously, hello and see you in the next clip, thank you.
