DIY alpha moped wiring repair

In detail: do-it-yourself repair of the alpha moped wiring from a real master for the site my.housecope.com.

The Alpha moped belongs to the category of the most popular vehicles in the budget category. The cost of the moped is low, the operating costs are also.

The wiring diagram of the Alpha moped differs from the diagrams of domestic motor vehicles, and for the better.

A simple electrical diagram of the alpha moped allows you to replace damaged items with your own hands.

The source of energy in the Alpha moped is the battery. Additionally, a relay-regulator is installed. The wiring is protected against voltage surges. The six-coil generator maintains voltage at all engine speeds, and also ensures uninterrupted operation of the lighting and signaling systems.

Installation of additional lighting devices is not provided. Also, you cannot replace lamps with more powerful ones. The absence of complex connections in the electrical circuit allows even a beginner to carry out repairs, which also affects the popularity of Alpha.

An electronic tachometer in the dashboard improves vehicle handling and driving comfort.
Alpha's low cost means that many factory parts are not of high quality. So, insulation of wiring is made of cheap plastic... As practice shows, operation in the harsh Russian climate leads to the fact that insulation is cracking.

That is why many recommend replacing the factory plastic wiring with a new one with rubber insulation immediately after making a purchase. In this way, you can insure yourself against the occurrence of various problems in operation.

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 massively imported to our country. And since the domestic motorcycle industry was in a recession, the new items came to the liking of motorcycle enthusiasts, and began to be massively purchased for their own needs.

Classic look of the Alpha moped

Of particular interest is the ALPHA moped with an air-cooled engine, which is sold on the territory of the Russian Federation as "Alpha 110ss" or "Alpha 49". The numbers in the title indicate the displacement of the engine:

49cc 4-stroke air-cooled engine cm, with a capacity of 4.5 hp;
110cc four-stroke air-cooled engine cm, with a capacity of 7 hp.

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

For reference: in China, several manufacturers are engaged in assembling the ALPHA model. Among them are Horse, Chong Qing Bull, WONJAN, Omaks and a number of others. In Russia, such companies as AVM and SMoto are also engaged in the assembly of mopeds. In this case, the wiring diagram of the Alpha moped is identical regardless of the place of assembly.

Unfortunately, the suppliers of motor vehicles do not always take into account the peculiarities of the performance of a particular type of vehicle, assuming that the low price is more important. In particular, most of the mopeds coming to Russia under the ALPHA brand are not designed for our climatic and road conditions.

This is manifested in the following:

Most mopeds are operated off-road (in rural areas, for trips to nature, fishing, etc.). And factory tires, cast rims, springs and shock absorbers are not designed for such loads;
The quality of gasoline and oil is also far from ideal, which affects the performance of the moped;
The moped does not provide for operation at subzero temperatures.

Tip: The wiring of the Alpha moped especially suffers from the harsh climate, since its insulation is made of cheap plastic. At negative temperatures, it becomes brittle and destroyed. Experienced owners replace it with rubber-insulated wiring after purchase.

In the same way as wiring on the Alpha moped, other "diseases" of the Alpha mopeds are cured with the help of replacement. In particular:

Factory tires are replaced with more durable tires;
Alloy wheels are being replaced by traditional spoke rims;
Shock absorbers are reinstalled from domestic motorcycles.

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

Electronic 12V ignition;
Electric starter;
Electronic tachometer in the instrument panel.

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

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 of the UAZ 31512).

Alpha wiring protected from voltage surges

The six-coil generator also does its job well:

Maintains voltage throughout the entire engine speed range;
Provides the work of the head light and dimensions while driving.

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

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

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

Speed mode;
Engine speed;
Battery charge state;
Daily and total mileage (see also the Ural motorcycle wiring diagram).

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

Replacement of parts and assemblies, whose resource has worked out;
Setting up and restoring the factory parameters of the main components and assemblies;
Visual inspection of the moped for breakdowns.

Chinese engines quite confidently "care for" 20,000 km on our domestic fuels and lubricants without breakdowns and piston group bulkheads. 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 cross-country, etc.), then all oil seals and rubber seals will also last a long time.

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

Please note that the provided electrical wiring diagrams do not differ significantly: all of them show the starter, generator, ignition switch and other electrical components. Differences can be in DC or AC power supply for lighting, etc. , regardless of the model. For example, in externally identical Alpha 110 mopeds, the wiring may differ slightly.

Generators can also be different:

2-coil (2-wire tachometer)
6-coil (3-wire tachometer)

As a result, the relay regulators will differ.

However, any electrical wiring diagram of the Alpha and Delta moped from the above will be useful when repairing and tuning the electrical connections of the scooter.
