The whole principle of operation of the starter on an alpha moped

The scooter does not start from the starter - reasons and methods for solving the problem

A common problem is that a scooter or moped starts with a kickstarter, but refuses to start with an electric starter. Let's consider all possible causes and methods for eliminating them. There may be several reasons why a scooter or moped does not start from the starter, both individually and in combination. Let's look at each of them:

Electric starter does not work

The scooter will not start from the starter if the electric starter itself is faulty. Everything is simple here. If the battery is serviceable and charged, the entire electrical circuit works, but when you press the starter button, only a click of the relay is heard, most likely the electric starter is faulty, or the contacts have come loose (oxidized).

It is very easy to check if the starter is working properly. Apply voltage to it directly from the battery, bypassing the starter relay. If the starter turns, then it is normal.

Starter relay does not work

The scooter will not start from the starter if the starter relay is not working. A faulty starter relay cannot start the starter, here everything is also simple and clear. If you do not hear the relay click when you press the starter button, it may be faulty. The relay needs to be replaced.

Starter button doesn't work

A failed electric starter button cannot close the circuit and supply power to the relay and starter, respectively. The button needs to be replaced. Sometimes wd-40 helps.

Brake contact (toad) does not work

As you know, modern scooters cannot be started from an electric starter without pressing the handle of one of the brakes. Each brake lever is equipped with a closing contact that turns on the brake light during braking. It is also responsible for closing the circuit to the electric starter.

Make sure that when you press the brake handle, the brake light is activated.

Contacts have come loose or oxidized

The starter contacts, as well as the starter relay chip, could have oxidized or come off. Inspect the contacts carefully and the quality of their connections. Make sure there is no oxide on the contacts.

Bendix doesn't work

If, when you try to start the scooter with an electric starter, the electric starter itself rotates and does not engage with the crankshaft, most likely the bendix has failed.

Dead battery

The scooter will not start from the starter if the battery is dead. A dead battery cannot crank the crankshaft with the proper force. Sometimes, when the battery is dead, the bendix does not transmit force to the crankshaft and we simply hear the starter twisting, as happens with a faulty bendix. Make sure the battery is charged.

The battery has failed

Over time, the battery capacity decreases, especially when used year-round. Such a battery, even if fully charged, instantly loses capacity under load. Even a fully charged battery, when trying to start it with the starter, can reduce the voltage to 6-8 volts. Starting the scooter with an electric starter in this situation will not work. The battery needs to be replaced.

Fuse blown

The fuse located near the battery could simply have blown.

If the turn signals, brake light and horn work, then everything is in order. If not, change the fuse.

Crankshaft seals are leaking

Check the crankshaft seals. If at least one of them shows signs of leaks, starting the scooter from the starter, especially when cold, will be problematic. Leaky seals need to be replaced.

Low compression

The most common reason for owners of scooters and mopeds to visit a workshop is that the scooter will not start from the starter, although all the electrics and battery are in order.

There is one rule, it’s better to remember - if the scooter starts normally with a kick starter, but doesn’t want to start with an electric starter, although the starter cranks the crankshaft perfectly and with sufficient force, the fault will almost always be low compression.

What does it mean? Most likely, your piston is already running out and you will need to change the piston with rings at best.

At the same time, question number two always arises - why does the scooter start from kickstarter? The answer is that when we rotate the kickstarter with our foot, especially when it is sharp, we turn the crankshaft faster.

A simple and understandable example can be given - remember the old pump with which you wanted to inflate the inner tube of your bicycle or scooter. Often these pumps do not have a sealed cuff that does not fit tightly enough to the walls. If you tried to slowly pump the chamber, all the air simply passed through the leaks in the cuff. And if you pumped quickly and with good effort, everything worked out. It’s the same here.

Types of multimeters and the principle of their design

The most common types of multimeters are analog and digital. Let's look at how they are designed and work below.

Analog

These are old-style testers that look like boxes with a glazed arc-shaped scale and a spring-loaded pointer. Often there is a mirror arc on the scale so that when you look at the arrow you can align the arrow with its reflection. This way, when measuring, you are looking exactly perpendicular to the scale, rather than at an angle, and it will be more difficult for you to make a mistake. The measuring panel has many parallel arc scales for different types of measurements:

Analog multimeter.

One of the main advantages of an analog multimeter is its low price and measurement accuracy that is quite sufficient for everyday purposes. Moreover, most analog multimeters have a built-in special resistor to adjust the position of the arrow exactly to “0”. For adjustment, a resistor head is used, similar to a screw slot, located below the measuring scale approximately at the point where the arrow is attached.

Digital

These multimeters are more modern and look like oblong black boxes with a large liquid crystal display for digital readings. These devices got their name because the analog signals entering the device are converted into digital form in an analog-to-digital converter (ADC). Such devices are more expensive than analog ones, but their size and weight are somewhat smaller, and it is more convenient and faster to work with them.

Some models are well suited for working in complete darkness due to the ability to illuminate the indicator panel (and electricians often have to work in dark rooms). You simply press a button and the panel lights up. In addition, you can find a model with the ability to record the readings taken into the device’s memory and subsequently transfer this data to a computer for further analysis. To do this, just press a special button. Typically, digital devices are used by professional electricians, electronics engineers and engineers.

Digital multimeter.

The measurement kit includes two wires with terminals and pointed probes:

• one black wire – “minus”, “ground”, “com” (common);
• the second red wire is positive or “measuring”.

It will be interesting How to check a resistor with a multimeter

The black probe is usually applied to the body of the electrical appliance (common busbar) or attached with a special clip - an “alligator clip”. The red probe is most often taken in the right hand and applied to different places in the circuit. The probes included in the digital multimeter are the same as those in the analog multimeter. Often the sockets are color-coded - red and black frames, so as not to accidentally confuse which probe is inserted where.

Sometimes the multimeter is a built-in part of another device, such as a digital clamp meter. Due to the need to be large, such devices have a large amount of free space in their housing, where the multimeter is built in.

ELECTRONICS OF ALPHA AND DELTA MOPEDS

Due to the fact that more and more owners of devices with engines of the 139FMB type and lights at recess are faced with six-coil generators (replacing the motor or preferably a more powerful generator), there is a need to write this article. First, let's figure out what the differences are. The picture shows a diagram

The electrical equipment of the mopeds under consideration consists of a source and consumers of electronic energy, auxiliary devices and an electronic network. Electrical equipment ensures timely ignition of the working mixture in the engine cylinder, operation of lighting devices and

Setting up and testing the scooter

Check the power interrupt switch. This safety feature "interrupts" engine power when you apply the brakes. If your scooter does not work after adjusting the brakes, then the problem lies in this unit.

Adjustment procedures may vary depending on the scooter model. You can usually loosen the brake adjustment tension by turning the brake adjuster built into the handle toward the lever. This releases the tension on the adjustment and safety switch. Check the owner's manual or contact the motor manufacturer.

If this setup doesn't work, there is an easy way to test the generator. Disconnect it from the controller, then try to start the scooter. If the problem is with the switch, then the scooter will only work when the brake lever switch is disabled. Make sure the power switch is turned on.

How to check the starter relay on a scooter

Main relay problems. Problems with the electric starter itself are not considered

Why is the pipe shit?

I disassembled my relay, unwinded the entire winding, re-wound it, cleaned the contacts, and now for the 5th year everything has been fine with the relay, my brain doesn’t work at all, there’s just no point in buying a new one, because there’s no guarantee of how long it will last enough again...

Tell me, I have a Honda Lead 90, the problem occurs when I start the scooter with the starter, I changed the bendex, weakened the spring on the bendex, revised the starter, it turns out that when I start the starter, the bendex engages the gear, I turned the crankshaft 2 times and after that the bendex goes to its original position and spins, but without rotating the crankshaft 

I have a Skymoto Spider 50 scooter and this is bullshit, the relay clicks but the starter doesn’t turn. If you connect the direct wire from the battery, the starter turns. I already changed the relay. What could be the reason. 

Tell me, my starter turns but doesn’t turn, I can take a video and post it, what should I do? battery is charged 

Thanks man, everything was explained clearly!

what to do if the relay clicks and the spark disappears?

the scooter does not charge the battery how to find out the reason

On Glushak Shit Pipe!))) Well, you need to buy a multimeter.

But what if the battery is charged, and the starter is on the button (as you say whack-whack), even if you bridge the contacts, the same sound zhik-zhik, I checked the battery with a multimeter and the charging of the battery while the engine is running, everything works, the Alpha Sabur 107cc moped is like written on the cylinder. 

I have such a problem, the scooter racer is generally Chinese, it won’t start from the starter, I took it apart and got to the relay, in general there is a spark, but there is no “whack, whack”, the battery is charged, what could be the problem?

Thank you Krasava helped. 

If all the wiring is intact, but this relay does not receive power, where to look? There's a diode in the wiring, maybe it's screwed up? 

I have the following question: when you press the starter button, the relay just clicks once and the starter doesn’t turn, this happened rarely before, but now I just can’t start it from the starter; I measured the voltage on the battery at 13.1 volts, but with the starter kick it starts normally. 

Teska! Both by first and last name! 

please tell me what should I do, I got into the wiring now the scooter is always turned on, even if you turn the key wherever you want, it still won’t turn off the ignition, what should I do or where to buy new wiring for the QM50QT-3M-Legend scooter

Folks, such a problem, I was riding a scooter (Viper Storm 50) and basically stopped, turned it off, put it on, after a few minutes I turn the ignition and nothing happens, no stops at all, nothing, the battery is charged!

Viktor Sokolov 4 months ago What if the battery is charged and the starter is on the button (as you say whack-whack), even if you bridge the contacts, the same sound zhik-zhik, I checked the battery with a multimeter and the charging of the battery while the engine is running, everything works, moped alpha sabur 107cc as written on the cylinder. 

Hello. Could there be a problem with my switch? I turn on the ignition, press the start button - the engine oils, but not enough. It starts from the claw. When it started there were no problems. The carburetor and piston are fine. 

“We specifically removed the battery right now. ” 4:30. And how does the relay operate when you shave it with a screwdriver if it is disconnected from the power supply? 

Does the starter relay affect the kickstarter?

Can problems arise due to the fact that you start the scooter using the battery from the car?

I didn’t understand at the end, if it’s okay, then the relay needs to be changed or changed when the starter turns normally. 

But what if it’s cold, zhi-zhi-zhi-zhi, but the engine doesn’t start? I start it with the kick and it’s fine, but with the starter it’s fine. Zhi-zhi-zhi-zhiiii. what to do ? 

Max, will the option not work if you install a 12Volt relay on a Honda according to the collective farm, changing the chips?

Mknya has no squeak squeak, it just doesn’t turn the button, but when I close it it starts. what should I do and why is this crap. 

I have this problem on a Viper 125cc, is it killing the battery? I’ve been riding for about a month now, and I’m already changing my 4th battery, what does this mean, can you tell me?? 

Maxim, hello buddy) please tell me, such a problem appeared on Tact 51 - I had a non-working starter relay, I removed the relay to take as a sample to the seller, now my stopak, turn signal and fuel sensor have stopped working, although the headlight and tail light have stopped working All contacts on the chips are lit, checked, everything is fine. what to do? what to check? Could something have burned out because I started the scooter without a starter relay? 

Method for checking the voltage regulator of a scooter

Chinese scooters are designed in such a way that their relay-regulator, which is also called a voltage regulator, often burns out. The voltage regulator is an electrical circuit with 4 terminals for connecting to the scooter's electrical network.

A malfunction of the voltage regulator leads to very disastrous consequences:

At first, the instrument panel backlight lamps and the central low/high beam lamp burn out. This happens due to the fact that the voltage from the generator is not limited to 12 volts, which leads to the lamps receiving an increased voltage of 16 to 27 volts and higher. The voltage supplied to the lamps fluctuates and depends on the engine speed. Even at idle, the lamps shine so much that they blind, although they should shine at half their maximum brightness.

If you do not remove the malfunction of the voltage regulator and leave everything as is (many do this - they just drive without lights), then over time the battery will fail because its charging voltage exceeds the permissible one. If the voltage regulator is faulty, the battery receives a voltage of more than 15 volts, while the standard charging voltage should be between 13.5 - 14.8 volts. All this leads to the fact that the battery begins to leak - acid begins to penetrate through the valves. This is noticeable to the naked eye. And although when the normal charging mode is restored, the battery restores its operation, its service life is sharply reduced.

Also, if the voltage regulator is faulty, the battery stops charging correctly and loses its capacity. Therefore, it is not possible to start the scooter with the button. You have to start it from kickstarter.

I think it’s now clear how important it is to change a faulty voltage regulator on a Chinese scooter.

How to check the voltage regulator on a scooter? It is best (and most reliable) to do this without dismantling the voltage regulator itself. We will need at least some kind of multimeter with a voltmeter function. Any ordinary DT-830 or similar will do. What should be done? It is necessary to measure the voltage at the output of the voltage regulator.

How to check if the relay regulator on a motorcycle is working?

How to check

Is the bike's alternator working? — .

All measurements were carried out on a Chinese scooter ABM Storm L ZW50QT-16.

To get to the relay-regulator, unscrew the front fairing in which the central headlight is installed. We find there on the frame a box with 4 terminals: red, green, yellow and white.

We put the scooter on the stand and start it. After some time, the engine operation stabilizes at idle. Next, measure the voltage between the green and red wires. We set the multimeter in DC voltage measurement mode to the limit of 20V. Here's a look at how you can do it.

The display should display a voltage of about 14.6 - 14.8 volts, as in the photo. This is normal, standard voltage.

Then we need to measure the voltage that goes to the lighting lamps. The voltage to the central high/low beam lamp is not constant, but alternating (pulsating), so we switch the multimeter to the 20V alternating voltage measurement mode. On the multimeter that I used (Victor VC9805A+), you need to press the DC/AC (Alternating Current) button to do this. After this, we measure the voltage between the green and yellow wires. We simply move the probe from the red to the yellow wire, since the green wire is the common wire in the scooter’s electrical network.

The multimeter display should show a voltage of around 12 volts. It showed 11.4 - 11.6 volts. This is normal as the scooter is idling. If you have an assistant, you can ask him to accelerate a little to increase the engine speed and, consequently, the voltage from the generator. In any case, the voltage should not change much and should be around 12 volts.

This was a voltage measurement at the output of a working voltage regulator (relay regulator).

Now let’s see what a voltmeter shows when measuring the voltage at the output of a faulty scooter voltage regulator.

Do-it-yourself voltage regulator for a scooter

You can make a relay regulator yourself; this requires a little knowledge and a scooter voltage regulator circuit. We will make a voltage regulator for a Chinese scooter with our own hands. The cheapest option is to use a shunt voltage regulator. The caveat is that for proper operation you need to disassemble the generator and remove the wire from ground with a separate wire.

It was decided to make a voltage regulator with your own hands for the reason that the Chinese analogues are so lousy that there are simply no words. Look at the photo of the Chinese voltage regulator circuit:

We will assemble a single-phase generator according to this circuit:

In order to make a relay regulator, you must first disassemble the generator and remove the stator from the engine. Now we see this picture:

The photo shows a mass that needs to be unsoldered, and to it we need to solder a separate wire to the winding. After which it needs to be taken outside. This wire will be one end of the winding. The other end is the white wire.

After this, carefully reassemble the generator in reverse order. Why was all this going on?! We now have 2 wires coming out of the generator, which we will use (there are 3 wires in total). All the changes that have occurred can be seen in the photo below:. The voltage regulator connection is shown in this scooter voltage regulator diagram:

The voltage regulator connection is shown in this scooter voltage regulator diagram:

OK it's all over Now. Our DIY scooter voltage regulator is almost finished. Now you need to connect the yellow wire from our old relay regulator to the “+” terminal of the scooter battery.

With the development of trade relations between Russia and China, in addition to traditional knitted goods and consumer electronics, various auto and motorcycle equipment began to be imported en masse to our country. And since the domestic motorcycle industry was experiencing a decline, the new items were to the taste of motorcyclists and began to be purchased en masse for their own needs.

Of particular interest is the ALPHA moped with an air-cooled engine, which is sold in the Russian Federation as “Alpha 110cc” or “Alpha 49”. The numbers in the name indicate the engine displacement:

1. 49 cc four-stroke air-cooled engine. cm, power 4.5 hp;
2. 110 cc four-stroke air-cooled engine. cm, power 7 hp.

Mopeds, due to their external resemblance to motorcycles, differ from scooters, although they represent a separate class. However, the combination of technical parameters, ease of do-it-yourself maintenance and low operating cost have made this moped a sales leader on the Russian motorcycle market.

For reference: in China, several manufacturers assemble the ALPHA model. Among them are Horse, Chong Qing Bull, WONJAN, Omaks and a number of others. Companies such as AVM and SMoto also assemble mopeds in Russia. At the same time, the wiring diagram of the Alpha moped is identical, regardless of the location of assembly.

What is a voltage regulator used for?

The relay regulator stabilizes the voltage of the scooter generator at the required level, not allowing it to increase or decrease the value above or below the norm. This prevents on-board voltage surges from going beyond the established limits (depending on the boards this is 12-14 V) and ruining the work of consumers whose service life is designed to be no more than 13 V.

That is, this part takes on the impulses that arise during the operation of the scooter (turning on the headlights, the starter button) and transfers the resulting thermal shock to itself. In this case, all the heat that could settle on the contacts is generated in it and removed through the device.

Moped manufacturers install charging relays with different parameters on scooters and select them individually for each. Depending on the regulator circuit, the connectors also differ. Chinese models usually have 5 terminals (male), while Japanese models have 4.

Service Features

Unfortunately, suppliers of motorcycle equipment do not always take into account the specific features of a particular type of vehicle, assuming that low price is more important. In particular, the majority of mopeds supplied to Russia under the ALPHA brand are not designed for our climatic and road conditions.

This manifests itself in the following:

1. Most mopeds are used off-road (in rural areas, for trips to nature, fishing, etc.). And factory tires, alloy rims, springs and shock absorbers are not designed for such loads;
2. The quality of gasoline and oil is also far from ideal, which affects the performance parameters of the moped;
3. The moped is not intended for operation at sub-zero temperatures.

Advice: The wiring of the Alpha moped especially suffers from harsh climates, since its insulation is made of cheap plastic. At sub-zero temperatures it becomes brittle and breaks down. Experienced owners, after purchase, replace it with rubber-insulated wiring.

In the same way as wiring for an Alpha moped, other “diseases” of Alpha mopeds can be cured with the help of replacement. In particular:

1. Factory tires are replaced with more wear-resistant ones;
2. Alloy wheels are replaced by traditional spoked rims;
3. Shock absorbers are reinstalled from domestic motorcycles.

Checking the VAZ 2107 regulator

Until 1996, classic VAZ 2107 cars with a cipher generator 37.3701 were equipped with an old-style voltage regulator (17.3702). If such a relay is installed, then it should be checked as on the top ten (discussed above).

After 1996, they began to install a new generator of the G-222 brand (there is an integrated regulator RN Ya112V (B1).

Checking the regulator separately

• 1 - battery;
• 2 - voltage regulator;
• 3 - control lamp.

To check, you need to assemble the circuit shown in the figure. At a normal operating voltage of 12 V, the light bulb should just glow. If the voltage reaches 14.5 Volts, then the light should go out, and when it drops, it should light up again.

Checking relay type 591.3702-01

Relay test diagram:

Such old relay models are sometimes installed on the classic VAZ 2101-VAZ 2107, on GAZ, Volga, Moskvich cars.

The relay is mounted on the body. It is checked according to the same scheme as the previous ones. But, you need to know the contact markings:

• “67” is the minus (-) contact.
• "15" is a plus.

The verification process is the same. At normal voltage, 12 Volts and up to 14 V, the light should light. If lower or higher, the light should go out.

PP-380

The RR-380 brand regulator was installed on VAZ 2101 and VAZ 2102 cars. Adjustable voltage at the temperature of the regulator and the environment (50±3) ° C, V:

• at the first stage no more than 0.7
• at the second stage 14.2 ± 0.3
• Resistance between plug “15” and ground, Ohm 17.7 ± 2
• Resistance between plug “15” and plug “67” with open contacts, Ohm 5.65 ± 0.3
• Air gap between armature and core, mm 1.4 ± 0.07
• Distance between contacts of the second stage, mm 0.45 ± 0.1.

Testing a three-level relay

As the name suggests, such relays have three voltage levels. This is a more advanced option. The voltage levels at which the battery will be disconnected from the voltage regulator can be set manually, for example: 13.7 V, 14.2 V, 14.7 V.

How to check the generator

To check functionality, you need to:

1. Disconnect the wires going to terminals 67 and 15 of the regulator.
2. Connect a light bulb to the wires. Bypassing the relay.
3. Disconnect the positive terminal of the battery.

If the car does not stall, then the generator is working.

Features of electrical equipment

Unlike domestic motorcycles and mopeds, Alfa already in its basic version has a number of advantages:

1. Electronic 12V ignition;
2. Electric starter;
3. Electronic tachometer on the instrument panel.

For reference: electronic ignition ensures trouble-free engine starting and stable operation in all operating modes. A simple circuit and the ease of replacing failed components with your own hands greatly simplifies the use of the vehicle.

Energy sources

The moped uses a circuit with a battery power source. The manufacturer does not recommend its operation without a battery, and the wiring diagram for the Alpha moped is additionally equipped with a relay regulator (see also the wiring diagram for UAZ 31512).

The six-coil generator also copes well with its duties:

1. Maintains voltage throughout the entire engine speed range;
2. Ensures that the headlights and headlights work while driving.

For reference: the factory instructions do not allow the installation of additional lighting fixtures. It is also prohibited to use headlight lamps on a moped that exceed the power specified in the technical documentation.

Control and management bodies

The presence of informative devices makes the operation of the moped quite simple, which attracts many buyers. Moreover, which is typical, a fairly large number of beginners decide to buy a two-wheeled vehicle, choosing Alpha mopeds.

The equally simple operation of the moped also contributes to its popularity. All the main functions of the vehicle are displayed on the steering wheel, and their status is displayed on the instrument panel:

1. Speed ​​mode;
2. Engine speed;
3. Battery charge state;
4. Daily and total mileage (see also Ural motorcycle wiring diagram).

Scheme and principle of operation

The operation of the stabilizer for all models is almost the same and consists in distributing the current supplied from the generator to stabilize it and further distribute it to consumers.

The main peripheral consumers of the scooter include:

• battery;
• indicators;
• light bulbs;
• sensors;
• enrichment agent;
• other nodes;
• starting enrichment.

How does the stabilizer work? The main principle of its operation is to act as a transformer, which lowers the voltage to an optimal level acceptable for the operation of electrical appliances, and also stabilizes the network and prevents unexpected power surges.

To avoid these problems and their undesirable consequences, you should know the basics of the correct operation of the electrical circuit and voltage components of the scooter (Figure 1).

The pinout of the relay regulator is standard for all models of Chinese-made scooters.

The stabilizer has an aluminum body and plastic contacts, each of which has its own wire. Each contact has its own wire color. This makes it convenient to connect the device to the wires if the plastic connector is worn out. The wires must be connected to the contacts according to the electrical diagram (Figure 3).

Moped maintenance

Like any vehicle, Alpha mopeds require routine maintenance, the essence of which boils down to:

1. Replacement of parts and assemblies whose service life has expired;
2. Setting up and restoring the factory parameters of the main components and assemblies;
3. Visual inspection of the moped to identify damage.

Chinese engines quite confidently “maintain” 20,000 km on our domestic fuels and lubricants without breakdowns or overhaul of the piston group. The main thing is to change the oil in a timely manner, especially during the break-in period.

If you do not operate the moped in harsh conditions (winter, cross-country racing, etc.), then all oil seals and rubber seals will also last a long time.

Tip: Change your air filter often. This will save the carburetor and make it easier to start the engine in all operating modes.
