Characteristics of generators for YaMZ engines
Generators for powerful diesel engines must provide stable DC voltage and sufficient rectified current power. Thus, the YaMZ 236 generator, which supplies engines of various modifications of BelAZ, Ural, KrAZ (model 1702.3771), is characterized by a rectified current of 50A and a rated voltage of 28V.
YaMZ engines are equipped with domestic electrical equipment, Radiovolna, ZiT, and Belarusian BATE generators. The G1000VK11.1 model for the YaMZ 238 engine produced is considered reliable.

Selection of generators for KamAZ and Ural trucks
Diesel generators for KamAZ and Ural trucks are varied in technical characteristics, depending on the model and engine power. To the defining characteristics of the G273V1
(YMZ-236, YaMZ-238 engines for Ural trucks) include maximum current (50 A), rated voltage (28 V), excitation current up to 4.1 A, weight 5.2 kg. An important improvement to the model was the possibility of seasonal adjustment. The integrated device in the “Winter” mode increases the starting voltage to 30V.
More powerful model 6562.3701
used in KamAZ trucks with KamAZ-7403, KamAZ-4310 engines. At the same rated voltage, a generator weighing 9.25 kg produces a higher maximum rectified current (90 A), reaches a power of 2520 W, and reaches a shaft speed of 6000 rpm at a current of 75 A.
Device
The generating set (GS) is a three-phase synchronous machine with excitation from an external power source and a rectifier unit. To control the output voltage and maintain it within specified limits, an integrated voltage regulator is installed.
The operating principle of the generator is based on the phenomenon of electromagnetic induction. The rotating magnetic field of the rotor, crossing the stator windings, induces an EMF in them, which is connected to the load through the rectifier unit. The main elements of the generator are:
- rotor;
- stator;
- front and back covers with built-in rectifier;
- brush holders with integral voltage regulator;
- fan pulley and impeller.
The generator rotor is a shaft made of electrical steel, on which an excitation winding (inductor) is wound. Power is supplied to it through 2 contact rings installed on the side of the back cover. 12 beak-shaped magnets are pressed onto the shaft. Ball bearings are installed at both ends of the rotor.
The stator winding is three-phase and consists of 36 coils. Each phase has 12 series-connected windings located in the stator slots and offset from one another by 120°. The electrical connection of the poles is made according to the “star” principle. The phase output terminals are connected to the rectifier unit.
A rectifier unit, voltage regulator and brush holders are installed on the back cover of the generator. The body elements are cast from aluminum alloy. In the center of each cover there is a place for installing a bearing. The fan impeller is installed on the rear end of the shaft, held from turning by a key and secured with a nut. In a similar way, a double-groove pulley is attached to the armature shaft in the front part of the GU. The design of generators of different models of MAZ cars is the same and differs only in the way they are connected to the network.

How to check the generator without removing it from the car
There are two ways, using a multimeter and without it at all. The first, relatively new one, is to check the voltage at the battery terminals, and the second, old and proven one, is almost the opposite - the battery terminal must be removed with the engine running.
- Checking the battery with a multimeter first occurs at rest - the voltage should be in the range of 12.5-12.8 V. Then you need to measure the readings with the engine running, if 13.5-14.5 V is observed at 2 thousand revolutions, then everything is in order. Moreover, on new cars, even 14.8 V is quite normal, as manufacturers claim - the abundance of electronics affects it. In conclusion, it remains to check the voltage under load , that is, by connecting consumers - the stove, headlights, heating, radio. A dip in the range of 13.7–14.0 V is considered acceptable, but 12.8–13 V already indicates a malfunction.
- The second method, like many “old-fashioned” ones, is simple and trouble-free, but at the same time quite dangerous and requires care . It allegedly works both on VAZs and on relatively new cars, like the Aveo. What is the point - loosen the bolt securing the negative terminal of the battery with a 10mm wrench, start the engine and give a small load, turning on one of the consumers, for example, the headlights. Then remove the terminal while the engine is running - if it does not stall and the headlights do not dim, then everything is absolutely fine with the generator, otherwise you can be sure that it is broken. You should try this method at your own peril and risk.
Having determined that there is a malfunction, you should dismantle and check the removed generator with a multimeter, a light bulb, and visually. Each of its elements is subject to verification separately.
Maz 5440 / 6430 euro - fuses and relays
Maz 5440 and Maz 6430 are the general designations for two series of truck tractors of the Minsk Automobile Plant produced from 1997 to the present with various modifications and changes (643008, 6430A8, 643005, 6430A5, 6430A4, 631208, 6312A8, 544009, 5440A9 , 544008, 5440A8, 544005, etc.) and generations (Euro 3 4 5 6). In this article you will find a description of the most popular fuse and relay blocks Maz 5440 and Maz 6430 with diagrams and their locations.
Block in the cabin
The main fuse and relay box is located in the passenger compartment, in the middle of the dashboard, on the passenger side and is closed with a protective cover.
The design of the block and the purpose of the elements in them depend on the year of manufacture and the level of equipment of the MAZ. The current designation for your vehicle will be printed on the back of the protective cover. Check the purpose, and in case of difficulty, contact your dealer.
