The wiring on the Delta moped is no different from the wiring on other Chinese scooters. It consists of the following parts:
- turn relay,
- ignition lock and coil,
- battery,
- spark plug,
- switch,
- voltage relay,
- starter;
- generator with flywheel.
Troubleshooting and repair of electrical equipment of the Delta moped
- The absence of a spark or its strength is not sufficient for ignition. To do this, unscrew the spark plug and evaluate its appearance. You should also check for a spark when turned out.
- When troubleshooting the ignition system, install a working spark plug and try to start the engine.
- Using a multimeter, check the contact between the motor and the frame.
- The performance of the generator can be assessed by measuring the coil resistance. Resistance is measured between ground and a black wire with a red stripe. If there is no resistance or it is very low, the generator is to blame for the problem. To confirm this fact, you should dismantle the generator and check the resistance directly on the coil.
- If the generator is working, check the integrity of the circuit. The electrical diagram of the Delta moped allows you to determine the procedure for troubleshooting and troubleshooting.
- Then the resistance at the terminals of the ignition unit is checked. Since this element cannot be repaired, if problems are identified, it should be replaced.
There may also be problems with the battery charging system. A sign of problems will be a constantly discharged battery . The cause may be a malfunction in the power supply system. Problem identification is done using a multimeter.
If the power supply system is damaged, no current flows to the battery. Until the battery is discharged, the scooter will work, and then the engine can only be started by charging the battery or replacing it with a new one.
The electrical circuit of the Delta moped simplifies the troubleshooting process. When performing welding work, you should remember that without disconnecting the switch you can easily destroy all electrical equipment.
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.
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.
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.
How to check the Delta moped generator?
If the Delta moped generator fails, this affects the operation of all systems. The presented unit provides electricity to the vehicle. If there are signs of a malfunction of the presented unit, you need to perform a comprehensive diagnosis and find out whether the problem really lies in the generator. High-quality and inexpensive motorcycles are sold in our Dvako motorcycle showroom. You can buy a Delta moped from us https://dvako.com.ua/mopedy/mopedy-delta and other models at a low price.
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.
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.
The current for lamps is not stabilized, but is limited to acceptable values. At high generator speeds, the voltage goes beyond the operating ranges of the lamps, which leads to their burnout. The situation is very familiar to those who have encountered faulty relay regulators.
Because of one unit, you can lose all the light bulbs in a matter of seconds, so you should monitor the on-board voltage regularly.
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.
general information
Consumer qualities
Buyers, first of all, are attracted not only by the fairly affordable price of mopeds of this brand, but also by:
- the ability to service the moped with your own hands;
- availability and availability of spare parts;
- ease of carrying out scheduled maintenance;
- Possibility of year-round operation.
Technical features
For convenience, technical information about the most popular moped from China is grouped into a table:
Chongqing Wonjan motorcycle China
For reference: the wiring of the Delta moped is designed for capacitor ignition. The photo below shows its schematic diagram.
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.

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)
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.
Such close attention to electrical equipment is due to the fact that when driving a moped, the low beam headlights must be turned on at all times. 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.
The battery deserves special attention for the simple reason that if the charging relay fails, the electrolyte will begin to boil away. (see also the article IZH Planet 2 wiring diagram: installation features)
Mopeds use 2 types of batteries:
- Traditional lead;
- Modern helium (maintenance-free).
Note! Gel batteries are afraid of being completely discharged. Therefore, prolonged movement with a full load on the electrical system is unacceptable.
Features of electrical equipment
The wiring to the Delta and all electrical equipment is quite traditional.
- 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.
We are sure that the diagrams presented in the article will help you in servicing Chinese-made mopeds. And the factory instructions will inform you about other features of a particular model.
