Just about the complex: Delta moped wiring diagram

What does a city dweller need to feel free and escape from the bustle of the city into nature? That's right, a two-wheeled friend that can take the owner not only on asphalt roads, but also over rough terrain. And best of all, Delta mopeds from China cope with this role, which delight with their bright design and ease of maintenance.

This appearance immediately attracts everyone's interest

Chinese mopeds

Single platform models

Today's realities are such that you can no longer see domestic models on public roads.

Times are changing, and the weakened banner of freedom from the hands of the domestic “Carpathians” and “Verkhovyna” was picked up by Chinese mopeds of the following series:

Let us state a fact: products from China have become widespread in the domestic motorcycle market.

Alpha;
Delta (DELTA);
Dino;
Irbis;
Viper (VIPER);
Zip Star;
Leader;
Mustang;
Breeze;
Dingo;

and other similar models, equipped with everything necessary for travel. These are all Delta “co-platforms” produced by the Chinese manufacturer Chongqing Wonjan motorcycle and the companies that bought a license from it.

For reference: It should be noted that Chinese technology has significantly displaced the products of domestic motorcycle manufacturers on the Russian market. This is noticeable not only in the form of finished products, but also in all kinds of components. For example, the Kovrov Motor Plant abandoned its own production of power units and installed the Lifan engine on its models.

Similarity of design

It is noteworthy that the electrical wiring of the Delta moped is similar to other models, which facilitates maintenance and increases the popularity of the vehicles.

Although seemingly complex at first glance, the electrical connection diagram is quite traditional.

Note! The photo above shows the wiring diagram for a Delta moped that does not have a tachometer on the instrument panel. It is identical for all models of this manufacturer, and differs only in the control of the semi-automatic transmission (Delta Racer model).

The video in this article will provide information regarding maintenance of similar models. For products with an instrument panel containing a tachometer, we publish part of the diagram, which also has differences in the controls. In this case, the wiring for the Delta moped is supplemented with several elements for connection.

Delta moped - review, repair, tuning

Many of us still have it in the garage, and it’s even usable. I note that this moped has absolutely nothing to do with modern Chinese-made models. And we will also look at the main differences.

First, let's test the first option, and then the new four-stroke Delta moped made in China. So, here it is, the pride of Soviet youth and one of the most popular mopeds of former socialism, the Delta moped made in the USSR:

In the village, he was an indispensable assistant and a kind of designer, because he broke down more often than he drove, and the developers are to blame for this, of course. But skillful hands always found a way out.

As additional styling on the delta moped, a windshield, arches, wind protection and simply a headlight frame were often used.

Tuning a Delta moped made in the USSR

Tuning a Delta moped consists only of replacing the rear sprocket, but this is not recommended, and without this the weak dynamics disappear completely, and you will have to work with your legs at the start, but this also has a plus, your legs will always be subject to physical stress. Although this cannot be ruled out in the other option, you will also often have to start the delta moped from the “pusher”, and this was normal at one time. But in return, if your piston is not worn out, you will probably get an increase of 10 km per hour, which is very little.

Engine tuning can be eliminated altogether; practically no one has done this due to its inexpediency. With proper running-in, a delta moped can be accelerated to 60 kilometers per hour, sometimes up to 65, but this happens extremely rarely. Two gears frankly do not cope with their task, and the device feels insecure throughout the entire acceleration, and it can be a stretch to call it acceleration; it is a sluggish increase in speed.

At one time, it was fashionable to raise the front fender, while the moped somehow resembled cross-country motorcycles, and it was cool, young people felt like real bikers, and frankly speaking, this was enough for many, since mopedists of that time were not spoiled by the technology that we can observe now, with a maximum speed of one hundred kilometers per hour.

Tuning can also include replacing the original tires with studded ones like this.

These tires hold up well in dirt and are suitable for use in the winter.

I advise you to forget and not remember about the rest of the tuning, you will only waste time, money, nerves, and then the moped will soon simply not want to work, without showing you an increase in dynamics and speed.

Repair of Delta moped made in the USSR

The basis of all the repairs of this device, of course, was the engine, it broke down very often, these were the rings, the piston, the clutch and much more. The owners of these mopeds fixed any malfunctions almost every day and ideally knew every bolt, of course there are positive aspects to this, you learned how to repair yourself.

The V-50 engine that was on the Karpaty moped was installed here, absolutely identical. Since I published the entire process of repairing such an engine in the article “Repairing a moped in the Carpathians,” I see no point in repeating it in this article.

Technical characteristics of the old-style Delta moped

— Displacement: 49.8 cm — Maximum power: 1.8 hp — Weight: 55 kg — Load: no more than 100 kg — Maximum speed: 60 km/h — Tank volume: 5 liters — Electronic ignition

At one time, the production of the Delta Afra moped was also established based on the old copy, but with more modern characteristics. This moped never gained popularity for a number of reasons and production was discontinued.

The new product had an elegant appearance and some semblance of a plastic cladding, new fenders, a headlight fairing, and a muffler. The trunk was cut down. An important difference was the snow-white alloy wheels.

What is interesting to the consumer

Why are city residents interested in the Delta?

The popularity of this model should be sought in the technical characteristics of the vehicle:

Electric starter;
More than moderate appetite - 2.5 l/100 km;
Four-speed semi-automatic (for Delta Racer model);
Load capacity 100 kg;
Easy to maintain with your own hands;
More than reasonable price for the model itself and spare parts.

Another electrical connection diagram from the spare parts catalog for Delta

Green, pink, yellow, blue and black-red wires

Please note that this wiring diagram is suitable for the vast majority of mopeds from Chinese brands. Moreover, it does not matter where exactly the vehicle was assembled. The same "Alpha" is assembled at 4 - 5 factories in the People's Republic of China and at a couple more enterprises in the Russian Federation. However, the design of Alpha motorcycle equipment produced at different production facilities will not differ.

All wires (pink, yellow, black-red, blue, green and others, because the diagram shows 17 shades) will be in the same places. And the connection will be carried out strictly in accordance with the instructions.

Features of electrical equipment

The wiring to the Delta and all electrical equipment is quite traditional.

It consists of:

generator with flywheel;
electric starter (with relay);
ignition coils;
electronic voltage relay;
spark plug;
battery;
electronic switch;
ignition switch;
turn relay.

This list is quite understandable to most motorists who have experience in servicing domestic equipment. Moreover, the wiring of the Delta moped is traditional - 12-volt, with a minus to ground.

Electrical equipment maintenance

What can overshadow the operation of a moped is its unpredictable breakdown. And although the manufacturer uses a fairly proven operating diagram for the main components and assemblies, nevertheless, failures in the operation of one or another electronic equipment are possible. (see also the article Features of wiring an Alpha moped)

Wiring to Delta requires attention to connectors and terminals

To avoid this, the owner is required to carry out scheduled technical inspections according to the manufacturer’s recommended periods (based on mileage):

Every 1500 km check and clean the spark plugs;
Every 800-1000 km, check the condition of the rear brake light (electrical connectors and the functionality of the incandescent lamp);
At the same frequency, check the operation of the head light (if the mileage is less, then at least once a month);
The condition of the battery terminals should be checked weekly.

Delta battery
Such close attention to electrical equipment is due to the fact that when driving a moped, the low beam headlights must be constantly on. This causes increased wear and tear on all elements of the electrical system. The wiring on the Delta moped also requires attention - the quality of its connectors and connections leaves much to be desired.

How to check the Delta moped generator?

Possible breakdowns

You can often find discussions on forums that the Delta moped has low generator voltage. The spark may be weak and the battery may not charge well. These are clear signs of a generator failure. This happens for several reasons:

The wire is burnt out or broken.
A short circuit has occurred.
The rotor magnetization dropped significantly.

If the voltage of the Delta moped generator drops, Nostalgia Kanuni, the cause may be a fall of the two-wheeler. Sometimes the explanation for why the rotor has become demagnetized is being near a high magnetic field. If the generator is not working properly, it becomes impossible to operate the moped.

Tuning Delta made in the USSR

The entire tuning of the Delta moped boiled down to changing the sprocket in the rear, although it is not advisable to do this; at the start you need to work with your legs, because even without this the weak dynamics are completely lost. However, there is a bright side: you will always be doing physical activity, which is good for your health. But this cannot be ruled out in another version: often, in order to start a Delta moped, you need to use a “pusher,” which was normal at that time. But in return, having an unworn piston, if you’re lucky, you’ll get an extra ten kilometers per hour, although this is very little.

The engine modification was not done at all, it was ineffective. If you test the moped correctly, it accelerates to sixty kilometers in an hour, sometimes even to sixty-five, but not often. To be honest, 2 gears cannot cope with the task, which is evident from how the Delta feels unsteady when accelerating, although it can hardly be called acceleration, it has a very low speed gain.

At that time, it was fashionable to have a raised wing at the front, since the device then looked like a cross-country motorcycle, which was actually a dream. The teenagers had the feeling that they were true bikers and, frankly, most bought it, because those who rode mopeds in those days were not spoiled by equipment of the kind that we see now, with a maximum speed of up to one hundred kilometers per hour .

Checking the part

How to check the generator on a Delta moped? First you need to check the output voltage of the node. To do this, you need to disconnect the wires in place of which the control device is connected. After this, you need to start the motor and measure the output voltage. The minimum indicator is at 5 V at idle speed. Next, the operation of the switch is checked:

The switch wires must be connected to the generator stator.
The commutator cable is disconnected from the terminal on the primary winding.
One pin must be connected to the motor ground.
The second terminal is connected to the main cable of the ignition coil.
The tester is set to the “direct current” position.
You need to crank the engine and look at the result on a multimeter.
The procedure is repeated again to obtain an average reading.

Checking the generator and its windings

It is the generator that allows you to produce a spark, so if the spark on the alpha moped disappears, look at the generator. First of all, look at all the contacts and wires adjacent to the generator. They can be either bare or broken off. After checking the contacts, diagnose condensates; they should work correctly on all mopeds.

In some cases, mechanical damage to the generator is possible; to do this, you will have to carefully inspect the winding for defects. If a problem is identified, it will be easier to replace the generator with a new one.

hello, I hope you can help me, I changed the central wiring on the alpha moped, I also changed the spark plug in the place with the armor wire and I have no sparks and the current doesn’t flow anywhere except from the ignition coil and that’s all what could be the reason

damn what to do please tell me I was riding an alpha 71kb moped and it started to stall and stalled and would not start again and I changed the spark plug and cleaned the corberator and it still did not start. And when you start it with your foot, sometimes it can shoot out of the pipe. Please tell me how to make a moped

Dmitry If the carburetor is in order and there is a spark, but the moped does not start, look at the valve head.

I can't start, can you help me?)

Why the hell are there extraneous sounds on the video, and so essentially nothing is said, so there are also extraneous sounds on the video.

Thank you very much helped

How much does armor wire cost?

help, I have no spark on my Verkhovina moped, what should I do?

Vitya Shapeev haha me too)

Hello everyone, take a look at my channel, I make different videos

Please give me some advice on why the Alpha moped does not have a spark, but it starts and there is a spark from the foot, the starter is spinning.

sprint 150cc spark not working

Where are you, I'll get you a motorcycle

Hello, how much does it cost to put a step on an Alfa moped?

Hello, I wanted to ask you, so I bought a 50 cc engine from an Alpha or Delta! And what do I need to buy to start it, what kind of wiring, so that it just starts from the kickstarter, basically from the stand!

Hello, I have such a problem. In the left cover, the coil was screwed onto 2 bolts, it turned out that 1 bolt was unscrewed and broke inside, there is a small hole on the magnet. I replaced the generator coil, ignition coil, and switch. Still no spark. Don't know what the problem is?

Denis, I have a spark, but it’s weak (it seems so to me). When starting with electric ignition, there is no such a confident sound (grinding), but a barely audible scrolling of the coil. What could this be?

Please tell me why there is no spark at the spark plug? I replaced the ignition coil, switch, and generator with new ones, still no =(.

I have the same problem((

Most likely the central wire (which fits the spark plug) needs to be replaced.

I have the same problem

Hello, I have a Trophy moped, such a problem happened when I turn on the turn signals they don’t blink and the dashboard doesn’t show that they are working either, what’s the matter, did I change the turn signals, maybe something wrong with the electronics?

+Denis Valerievich Thank you!

Most likely the turn signal relay has failed.

Wiring diagram of a Chinese scooter 4t 50cc

Modern scooters made in China have a similar layout. The engineers of the Celestial Empire did not bother and assembled all the critical components according to a single scheme. Even if there are differences, they are minimal.

This statement is also true for the electrical components of the moped. Any owner periodically encounters problems associated with these nodes. The electrical circuit of a Chinese 4t scooter is not a complex system; it contains only the main elements necessary for the full operation of the unit.

Knowing the main electrical wiring components and their purpose, you can quickly find the problem and fix it.

Delta moped wiring diagram china

The electrical circuit diagram of Chinese scooters is shown in the figure:

As with other electrical connections, there is a common wire on all cube mopeds. In this diagram it is the negative tire running along the entire body. The corresponding battery terminal is also connected to the scooter's frame, ensuring that each electrical component's ground is in constant contact with the power source.

Electrics and electrical equipment of a scooter

The main components in the 4t moped circuit are:

central locking;
battery charging source – generator;
voltage limiter;
spark formation and control systems;
control elements for headlights, brake lights, turns;
fuel level indicator in the tank.

All circuits are connected together using wiring.

Depending on the modifications and dimensions of the scooter, the instrument panel may include a tachometer - a device for monitoring the number of engine revolutions.

All of the listed nodes of the general scheme perform a strictly assigned role. Failure of at least one of them leads to the cessation of operation of the connected devices. Therefore, monitoring the serviceability of the main elements must be done every certain period for the purpose of prevention.

No spark on alpha moped

Mopeds made in China break down quite often, this depends not only on poor-quality parts, it is important to operate the moped correctly and monitor the condition of its parts. But many owners of Alpha mopeds are faced with a problem when their vehicle simply does not start. After reviewing most of the possible causes, the owner notices that there is no spark on the moped. Without a spark, the moped will not start, and there can be several reasons for the breakdown. Most of the reasons are quite banal and lie in minor breakdowns, but if all the steps below do not help, you will have to completely rebuild the moped or take it to a specialist. Diagnosis of lack of spark is carried out in several procedures below.

Checking the generator and its windings

Spark plug diagnostics

In most cases, a spark on an Alpha moped does not appear precisely because of the spark plug; this is a consumable part that often breaks. Therefore, first of all, we check the spark plug for external defects. The candle may overheat or simply outlive its useful life; there may be cracks in the ceramic or other damage. Also carefully inspect the candle for its color; it should be clean and free of carbon deposits. The problem can be solved simply - just buy a new spark plug.

Battery

When using a battery, a weak spark may occur on the alpha moped, or it may simply disappear due to insufficient charge. The moped owner should always monitor the battery charge level; most Alpha moped batteries have a 12-volt battery, so when checked, the device should show at least 9 volts. Indicators below this mark indicate a failure of the battery, which in turn does not produce a spark at the spark plug.

Checking the distributor

The distributor is a common reason for the lack of spark on a moped, so if the above parts are working, we check the distributor and the wires leading to it. Sometimes a defect is noticed on high-voltage wires that lead to the distributor, so inspect their external condition.

Ignition coil

And finally, the last, but one of the most important reasons for the lack of a spark, is the ignition coil, or rather its breakdown. With the proper knowledge, you will have to check the functionality of the ignition coil; to do this, you need to connect a low-power light bulb to it, which should check the current supply from the coil.

In most cases, you can fix the lack of a spark yourself; fortunately, the design of mopeds such as Alpha is quite simple, the design is created in such a way that all parts are visible and can be quickly replaced. Also, the cost of spare parts for Alpha mopeds is low, which is a big plus. But if you cannot find the cause of the breakdown yourself, we recommend turning to professionals.

Egnition lock

This component in the circuit of a 4-stroke 50cc or 150cc moped represents a switch. Moreover, it is multi-positional.

The lock performs the task of a central switch. It turns off the power to the entire scooter and turns the circuit back on when you turn the key. The larva itself is connected to a slider, which closes the corresponding contacts.

In the first position, the main wires interact - red and black. Current from the battery is supplied to the main circuits of the scooter. Since then it has been ready to launch.

The remaining positions close the black and white wire from the ignition module to the ground of the scooter. The operation of the motor is blocked by interrupting the spark supply from the coil. Depending on the modification, some models have a stop button in the electrical circuit. It performs the same function as the lock.

Ignition coil

Generator

Owners of 50cc who are familiar with the design of the scooter will immediately understand the purpose of this device. It produces an alternating electric current that powers the moped when the engine is running. But the second main task is to charge the battery while working. That is, the battery ensures the operation of the devices when the engine is turned off, and then the generator takes on this task.

The connection is made according to the following principle. There are several wires coming from the generator. The negative tire is attached to the frame of the scooter. There is alternating voltage on the white wire, which is immediately sent for rectification and stabilization.

In the electrical circuit, the yellow wire powers the low and high beam lights. Additionally, a Hall sensor is located in the generator housing. Its task is to generate impulses to control sparking. It is not electrically connected to the generator; it is connected to a white-green and red-black wire. The sensor is connected to the CDI block.

Relay regulator

This is the same rectifier that converts alternating voltage to direct voltage, with a range of 13.5-14.9 V. C

The regulator is located under the plastic cover of the scooter at the front. It is attached to a metal backing for better heat dissipation.

The main circuits of the relay circuit are:

The green wire is common.
Red – output of converted and stabilized voltage within the established limits.
White and yellow – AC input to the regulator. Due to electronics, the voltage is converted into powerful impulses. The yellow wire supplies power to a heavy load on the on-board network - headlights and instrument panel lighting.

Ignition circuit components

The ignition system is an important element in the operation of the entire scooter. The formation of a spark and a precisely calculated impulse that ignites the fuel depend on it.

The scooter ignition circuit includes many components that are responsible for a specific job.

CDI ignition module

The first item in the list is the CDI module. This abbreviation stands for Capacitor Discharge Ignition - ignition from a capacitor discharge.

The switch module is made in a non-separable box, so if it fails, it is replaced with a new one. 5 wires are connected to it, distributed throughout the entire ignition circuit of the scooter.

The block is hidden inside the scooter, so getting to it is not easy. The plastic covers will have to be completely dismantled.

Ignition coil

The purpose of this component is a fast pulse of high voltage voltage based on a signal from the switch. It goes directly to the spark plug, where it is converted into a spark.

The coil is located on the right side of the Chinese scooter and is attached to its supporting structure. It is easy to recognize - it is made in the form of a plastic barrel. On the reverse side there is a thick wire connected. It is he who transfers the discharge according to the circuit from the transformer to the spark plug.

To protect against dirt and dust, the coil is placed in a rubber cover.

Spark plug

Its function is simple - to form a spark and ignite the mixture inside the cylinder. The scooter uses an A7TC spark plug.

Its position is hidden from view, but experienced owners know where to look for it. Having passed along the high-voltage wire, we reach the engine block and the spark plug cap.

The rubber seal protects the contact from accidental electrical breakdown. Remove with a little effort towards you. Do not pull the wire too hard - the cap may come off.

The spark plug is unscrewed with a socket wrench. After removal, you need to inspect the color of the contacts and their condition. An indicator of good engine performance is a brown tint without traces of soot. Deviation from the norm indicates a malfunction of the carburetor.

Starter

The device is used to make it easier to start a scooter engine, without using a kick pedal. The starter is located in the middle part of the moped, near the engine. To open it, you need to remove the decorative plastic.

The starter is connected through the starting relay, which is located on the scooter frame.

Fuel gauge and indicator

The sensor measures the amount of gasoline in the tank and signals the need to refuel. It is located in the tank itself and is connected by three wires.

The indicator is directly connected to the sensor. Both are powered by stabilized current from the rectifier. If problems are observed in the operation of the indicator, you should check the connection to the circuit.

Voltage is supplied only when the ignition switch is turned on.

Turns relay

The breaker is used to control the turn lights. When the button is closed, the relay produces current pulses with a frequency of 1 Hz.

The block is located under the instrument panel. To change the relay you need to remove the plastic protection.

Switching the circuit is not difficult. When turning right, voltage flows through the blue wire, which is responsible for the corresponding lamps. The left position of the switch shorts the gray bus to the orange one.

Duplicate lamps on the instrument panel are connected in parallel to the turns circuit lines. They signal that the lamps are on on a specific side of the scooter.

Sound signal

The purpose of the sound horn is clear to everyone. On the scooter it is located near the limiter relay.

The signal is powered by direct current through the ignition switch and is activated by a button on the handlebars of the moped. The component is non-separable, so if it fails, it is completely replaced.
