You need to avoid getting confused which wire goes to the right and which to the left; try marking them for yourself. Rotate the crankshaft until the marks on the flywheel and crankcase align.

When sliding batteries 1 out of container 10 onto bracket 3 and removing them from the vehicle, take precautions to prevent an unsecured battery from falling.

When installing the generator on the engine, keep in mind that the rear bolt securing the generator to the bracket is secured in a split support, and the leg of the front cover of the generator is attached without clearance. And she left me.

If the voltage is outside the technical specifications, replace the regulator. In addition, you can significantly save on fuel.

Don't forget to purchase an anti-theft lock for your motorcycle. Period of years The wiring of the Ural motorcycle has also proven itself quite well - if at first the designers had concerns about loss of contact due to possible corrosion of the metal frame, then operation has shown the reliability of the single-wire electrical circuit. I always turn off a lot of my own stuff automatically after I’ve turned off the engine, and such a small wiring upgrade doesn’t bother me.

How to connect the ignition switch on a Ural motorcycle with a contact diagram: In this case, in addition to the basic operations, you will also have to fix the gap between the contacts located in the breaker. See also the Moskvich wiring diagram. Check that the ignition is set correctly. If the control lamp lights up or does not light up when it is turned on in both directions, then the unit diode is faulty. I was really surprised by the ice.

Electrical circuit of the motorcycle Ural Solo, Solo Classic, Wolf

So, how to connect the ignition switch on a Ural motorcycle: Collect the necessary tools: keys, a thin sheet of paper, etc. Install the crankshaft at TDC of the cylinder; Unscrew the spark plug from the cylinder block, cover the hole from the spark plug with paper; Loosen the microblock fasteners until it rotates. The procedure for disassembling the generator: unscrew the two screws securing the brush holder and remove the brush holder; unscrew the coupling bolts and remove the cover from the side of the slip rings along with the stator; unscrew the nuts securing the phase leads from the rectifier block and separate the stator from the cover; Unscrew the pulley mounting nut and remove the pulley, fan, and support sleeve.

If the clamp 13 is clamped between the battery 1 and the rear wedge stop 12, use a screwdriver or a bit inserted into the hole at the end of the clamp to remove the clamp. Voltage level markings are located on the front cover of the regulator. MOTORCYCLE URAL WIRING CONNECTION PART 2

MY MOTORCYCLE

What is generator No. 14.3771 with a power of half a kilowatt for “opposite” vehicles? This unit, if compared with our time, is no longer new, but also not old, compared with the G-424. He has proven himself quite well in the circle of “Ural specialists”. Therefore, let’s talk in more detail about the design of this generator.

To begin with, a small excursion into history. Back in 1973, the first major fuel crisis broke out in the wild West. Demand for large and power-hungry cars fell sharply. The economy of Japan, which does not have its own oil fields, experienced particular shocks. In these harsh conditions, Japanese designers were almost the first to solve the problem of how to reduce gasoline consumption. The weight of vehicles should be reduced, but not at the expense of their service life. This affected all components and parts, both large and small, including even electrical equipment and the generator set. kept up with the Japanese in the development of generators. As a result, in the early seventies, a modern type of generator, the so-called “compact” type, was formed.

Rice. 1. Graph of the dependence of the current generated by the generator on the rotor speed.

Our half-kilowatt motorcycle also belongs to this type. During its development, many modern requirements were taken into account: the generator power must be sufficient to ensure a positive balance of electricity under any operating conditions; reliable cooling; overall and connecting dimensions should not increase (this will allow the new generator to be used on engines of previous years of production without any changes); The integrated voltage regulator Y212A11E (or 36.3702) is built into the generator set, which simplifies the overall wiring diagram of the motorcycle. The only technical solution, usually used on modern car engines with “compact” type generators, but not used when creating the 14.3771 generator, is to increase the operating speed of the generator by changing the gear ratio to - 1:3 with a polyhline (“ribbed”) belt. The use of new generator drive gears on the Ural motorcycle requires the creation of a new crankcase and eliminates interchangeability with parts of old engines. They refused to change the gear ratio, but the complex of technical solutions used allows us to classify the 14.3771 generator as the most modern. Some may wonder if the power of the 14.3771 generator (14 V; 35 A) is too high? Let's look at the graph of the relationship between the current supplied by the generator and the engine crankshaft speed. And let’s do the math right away: the ignition system plus the side light and the brake light lamp consume a current of about 5-6 A (Fig. 1 - dotted line). The old G-424 generator could provide these very modest needs, starting at almost 2000 crankshaft rpm. As a result, when it was necessary to drive at low speeds (both on country roads and in city traffic jams), the battery was chronically discharged. Having the headlight on at night completely spoiled the whole picture - it shone dimly and inexorably brought the end of the battery closer. The main advantage of the generator is not even the high maximum power, but the fact that already at 900...1000 rpm of the crankshaft (at idle!) it is capable of delivering a current of 15 A - like the G-424 at full throttle ( see Fig. 1).

Let us consider in detail the design of the generator. The increased power required more efficient cooling, so the fan impeller is located inside the housing, at the front end of the rotor. The body itself is made with numerous ventilation holes. The use of “heavy” series ball bearings in combination with dynamic balancing of the rotor on a computer bench made it possible to significantly increase the service life of the generator. This is facilitated by the impregnation of the rotor and stator windings with a hot-drying epoxy compound for better protection from water, dirt and vibration. The rotor design has undergone the greatest changes. The brush assembly is located from the internal cavity of the generator to the rear shaft shank. This made it possible to bring the bearings closer together (to improve vibration resistance) and to use slip rings with a diameter smaller than the generator shaft. As a result, the service life of the rings increased due to a decrease in the peripheral sliding speed of the brushes. The built-in rectifier unit consists of eight power diodes placed on aluminum radiators on the back cover of the generator (each diode is rated for a current of 20 A). Six of them make up a three-phase rectifier bridge. The remaining two diodes in the motorcycle modification of the generator are not used and are not connected anywhere. An additional rectifier arm has also been introduced into the electrical circuit. Three small diodes (each with a current of 2A) are located near the inner edge of the “horseshoe” of the power rectifier. This made it possible to eliminate the discharge current through the excitation coil when the ignition is on and the engine is not running, as well as to relieve the ignition switch contacts (switching power to the excitation winding) when the engine is running.

The integral regulator Y212A11E or 36.3702 is built into the brush assembly of the generator. The above-mentioned regulators are produced by different factories and, despite the difference in markings, have exactly the same internal structure and are completely interchangeable. According to the standard, the response threshold of the Ya212A11E and 36.3702 regulators should be in the range of 13.6-14.4 V. The electrical circuit of the new generator set is somewhat different from what our motorcyclists are used to and requires explanation. When the ignition is turned on, the “LC” indicator light comes on, which confirms the functionality of the excitation circuit. After starting the engine, the generator begins to generate voltage and the “LC” lamp goes out, since a voltage equal to the voltage of the battery appears at the “D+” terminal. In case the “LK” lamp burns out, a resistor “R” (56 Ohm, 2 W) is connected in parallel with it. In extreme cases, the “R” resistor may not be installed, but then you need to carry a spare light bulb with you (12V, 2-4 W).

Rice. 2. Electrical installation with generator 14.3771: 1 - instrument panel or headlight; 2 — generator excitation resistor (560 Ohm and 2 W); 3 — connector for connecting an electronic tachometer. 4 — power (positive) terminal of the generator: 5 — connector of the generator excitation circuit.

The section of the power rectifier not involved in the operation of the generator (shown in Fig. 2 in orange) was supposed to be connected to the zero point of the stator winding (the non-existent wire is shown in an orange dotted line). A circuit connecting the zero point to the rectifier can increase the power supplied by the generator, but by no more than 10-15% (- 3 A). However, they decided to neglect such an insignificant increase in order to simplify production. When the generator operates at the “W” terminal, an alternating voltage appears, the pulsation frequency of which depends on the engine crankshaft speed. This terminal was originally intended for connecting an electronic tachometer.

As already mentioned, the 14.3771 generator can easily be installed on motorcycles of previous years of production. To facilitate this task, a diagram of the previous generating set with the G-424 generator is provided (Fig. 3).

Electrical equipment

The electrical equipment system is single-wire, the negative pole of power sources and consumers is connected to the vehicle ground. The negative terminal of the battery is connected to the vehicle ground using a remote switch. The sources of electricity are two batteries connected in series and a generator operating in conjunction with a voltage regulator. The connection of units and electrical equipment is carried out using wires with polyvinyl chloride insulation of various sections. The wires included in the bundles are made of a certain color to make them easier to find and easier to install. Single wires can be made in any color. The color of the wire can be indicated on the cuffs installed at both ends of the wire, the first letter of the color. The wires are connected to each other and connected to devices using plug connectors. The colors of the car's wires are included in Appendix 4. The car is equipped with a mechanically driven speedometer, electronic devices and systems: tachometer, generator with a rectifier unit, etc. To avoid damage to the flexible shaft of the GV300-05 speedometer, it is necessary to lay the flexible shaft in this way when installing and dismantling the instrument panel in such a way that the paint mark on the shaft shell is located outside the cabin directly behind the sealing sleeve of the flexible shaft through hole, while the flexible shaft must be routed without forming a loop behind the instrument panel. For reliable operation of these devices and systems, it is necessary to monitor the condition of the fuses installed in the blocks. Do not use non-standard fuses in the form of bent wire, bolts, washers, as in the event of a short circuit in the electrical circuit, this will lead to immediate failure of electronics-based products. A blown fuse should be replaced with another one of the same intended operating current.

Outlaws MC

Using the probes of the device in the “continuity” mode, check each terminal of the stator winding for a short circuit to the housing. There should be no short circuits. This affected all components and parts, both large and small, including even electrical equipment and the generator set. A design feature of the voltage regulator is that the adjustable voltage switch consists of reed switches and a magnet that controls them, which is located in the handle that switches voltage levels.

The difference in the above diagrams is in the relay regulator.

In particular, automatic ignition timing was introduced, since the motorcycle received a new power unit, and the old manual control of the timing advance did not meet the technical requirements. The section of the power rectifier not involved in the operation of the generator is shown in Fig.

Make sure that the upper clamps are installed in the guides I. To check the condition of the brush assembly, remove the brush holder.

The remaining two diodes in the motorcycle modification of the generator are not used and are not connected anywhere. The generator can also be checked by connecting one end of the wire to a portable lamp to ground, and the other to terminal I of the relay-regulator, while the wires should be disconnected from terminals Ш and И.
