How many volts should a moped alpha generator produce?

Ignition coil T1 with spark plug FV1 is located outside the switch and is shown conditionally.

One of the contacts, of course, is common.

Ignition coil 2. Dashboard alpha modification

It is worth noting that the high-voltage wire is connected to the cap without soldering.

To protect against dust, dirt and accidental short circuits, the coil is covered with a rubber cover.

On a scooter, the common wire is minus -.

The relay regulator on Chinese scooters is installed in the front part under a plastic fairing. There are other voltage regulator relays, where the colors are even more changed, but more about that later.

They are supplied with power from the battery.

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.

Or “raise the white flag and call SOS” - call a “tow truck” on your mobile phone. It comes from a relay regulator or battery if the engine is turned off through the ignition switch and the horn button

You can even play around a little and adjust these steps to the graph of the break in the ignition timing change curve.

When the engine is idling and at low speeds, the amplitude of the pulses coming from the induction sensor is less than the stabilization voltage of the zener diode VD4, therefore only later pulses of negative polarity pass to the input of the triac VS1, for which the zener diode is connected like a regular diode in the forward direction.

Green is the common wire. And if you look at the number of wires of such a relay-regulator, we see four of them. ALPHA TIDY! HOW TO CONNECT THE DEVICE ON ALPHA! INSTALLATION OF MOPEDS

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

How to check the starter relay on a scooter

Main tasks of the relay

. Problems with the electric starter itself are not considered.

The “Delta”, “Alpha”, “Leader” and “Mustang” mopeds use a 12 V battery with a capacity of 2.5, 3.0 or 5.0 A/h (Table 6.1). Inside the case, the battery is filled with a chemical reagent and electrolyte. Battery maintenance involves periodically checking the level and density of the electrolyte.

The source of electricity for mopeds is a generator (magneto), the rotor of which is mounted on the left axle of the engine crankshaft. Flywheel type generator, alternating current, with excitation from permanent magnets. To diagnose a generator, special equipment is required. Disassembly

One of the main elements of the moped's electrical system is the voltage regulator-rectifier. The appearance of the voltage regulator-rectifier is shown in Fig. Rice. 6.6. The voltage regulator-rectifier performs two functions: it ensures the voltage in the moped network within the range of 12.0-14.5

The Delta, Leader and Mustang mopeds use a contactless CDI ignition system. The CDI ignition system eliminates the weak link of the traditional ignition system

, i.e. wear out quickly and require frequent adjustment of breaker contacts. The abbreviation "CDI" comes from the first letters

Spark plugs (Fig. 6.11) recommended by the manufacturer for A7TC or A7RTC SX four-stroke engines. Analogues of these spark plugs are NGK C7HSA or NGK CR7HSA, Champion Z9Y. The technical characteristics of the spark plug are given in table. 6.9. The gap between the spark plug electrodes should be 0.6-0.7 mm. Regulatory replacement

The electromagnetic sensor of the ignition system (Fig. 6.12) is located on the stator mounting plate in the left engine cover. Checking the electromagnetic sensor of the ignition system You can test the electromagnetic sensor of the ignition system without removing it from the engine; for this you need to: measure

The starting system includes the starter, starter relay and starter drive. The appearance of the starter is shown in Fig. 6.13. The starter is a mixed-excitation DC electric motor and is designed to start the engine. On mopeds “Alpha”, “Delta”, “Leader”, “Mustang”, etc. can be installed

The starter is removed in the following order: placing the moped on a flat surface, disconnect the “-” terminal from the battery; disconnect the terminal wire from the starter (Fig. 6.17); Unclench the spring ring lock with pliers and remove the starter sprocket along with the chain from the splines (Fig.

, connecting directly to the power source (Fig. 6.20).
With this connection, the starter should rotate. If the starter does not rotate, you need to disassemble the starter housing and check the starter parts: brush length

Principle of operation

Inside the body there is a movable cylindrical element called a rotor (in collective farm language - an anchor). An insulated copper wire is wound on the rotor in a strictly defined order, forming several independent coils, circuits, windings, poles, circuits - which, in fact, is the same thing. The ends of each of the coils have their own independent outputs in the form of lamellas (contacts) on the collector.

Inside the main body, two permanent magnets are glued exactly around the rotor. Each of the magnets has a different pole N (north) S (south) in relation to each other. Anyone who went to school will understand...

After you press the start button, the electric current from the battery will begin to pass through the power terminal, the brush and then, passing through the lamellas of one and the rotor windings - it forms a constant magnetic field along the axis of the armature.

I think there is no need to explain that the magnetic field that forms a constant electric current has different polarities? So that's what I'm talking about. Oh yes, the magnetic field of the rotor will begin to interact with the magnetic field of the permanent magnets and the armature will deviate by a certain degree. The commutator will turn, the next pair of lamellas will approach the brushes and the rotor will deviate again. Thus, it will rotate exactly until you lower the start button.

But what to do if the battery is charging, and the starter is from the button (as you say Whack. Whack), even if you connect the contacts, the same sound Zhik-Zhik, I checked the charging of the battery and battery using a multimeter, while the engine was running, everything worked . Alpha Sabur 107cc moped as written on the cylinder. A.

Checking the starter

Without removing the starter from the engine, we look for the power terminal on its body and disconnect the wire from it. We remove the battery (charged) from the scooter, look for it, ask someone for it, or buy two pieces of thick copper wire. Connect the wires to the battery terminals. Then, we apply the wire coming from the negative terminal of the battery to the starter housing, and the second wire - coming from the positive terminal of the battery - is applied to the starter power terminal

1. If the starter works, then it is fully operational and the cause of the problem must be looked for in the relay, start button or wires supplying power to it
2. If the starter does not work, then the fault lies in itself and it needs to be removed, disassembled and checked. It is quite possible that it can still be repaired and save a lot of money

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:

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.

Appearance of Alpha RX

Alpha RX is an updated version of the previous classic moped. The new moped has become more interesting and elegant in appearance. The exterior has a modern look which I liked. The tank has been updated, a two-level seat has been installed - the passenger is now slightly higher than the driver. The passenger's visibility is now better. The wings are now made of plastic, but only the front wing is painted. This already saves the wings from corrosion.

The headlight became larger than that of the classic Alpha, a serious halogen lamp was installed, and the light became brighter. The rear shock absorbers have become more advanced in shape. The motorcycle is also equipped with serious lighting equipment - front and rear lights, turn signals with sound, high and low beams, a signal and a brake light.

Very easy to use. Repair is possible with a minimum set of tools, but you will have to stock up on additional open-end wrenches: 9, 11 and 15.

It comes in two versions for sale: with a 72 cc and 110 cc engine. But lately they have been supplied partially unserviceable with a 50cc piston that will need to be upgraded. These versions of the models are called Alpha 7 and Alpha 11.

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:

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:

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.

Features of electrical equipment

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

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:

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:

Engine Specifications

The moped is equipped with a 4-stroke air-cooled engine marked 1P39FMB. The marking means that the engine has a piston with a diameter of supposedly 39 mm and the engine has a volume of supposedly 49.9 cubic cm.

The advantage of such an engine is that there is no need to mix gasoline and oil. But unlike a 2-stroke engine, which is structurally simpler, here you need to monitor the valve clearance. Plus, the engine is equipped with an oil pump, a drive chain and a chain tensioner.

Moped maintenance

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

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.
