Schemes of electrical equipment of cars Gazelle GAZ
I am the owner of a 1998 passenger gazelle. Or another, adhering to the conventional and color designations, you can independently replace the old wires. Accordingly, for example, ZMZ-4061 or ZMZ-4063, the owners prefer a more modern injection motor that they are going to replace the engine with a Gazelle. If the resource is recoverable power unit inspires optimism, and there is a Gazelle wiring diagram at hand, the 402 engine may well last more than one hundred thousand kilometers. Tip: the Gazelle 402 wiring has color divisions shown, which correspond to the colors. Very often, Gazelle owners, when replacing power units from carburetor versions to injection versions, since there are serious differences in the electrical circuit, are faced with the need to replace electrical wiring in the car. Leaving in the past the carburetor, and the old tank design is not suitable for this; The new injection engine ZMZ-406 is more demanding on the cooling system, the replacement of the power unit inevitably entails the replacement of the power system: Installed new gas tank, which also needs to be connected to the car's regular electrical network, since the injector must dump excess fuel back, so when installing a new power unit: Do not forget that the injection engine power system is controlled by an electronic unit. Gazelle 406 wiring diagram: do-it-yourself wiring installation features on this type of motor, differences between a carburetor and an injector, instructions, photos, videos. Accordingly, than on older versions of a car with 402 series engines, and is subject to mandatory replacement, on the Gazelle 406 the wiring is different. More complex are the interior and engine compartment. The Gazelle, which has become an indispensable vehicle with a 402 engine, still requires attention over the years. The article came in handy, a great helper for my future engine replacement and therefore wiring. The simplest in terms of connection is rear end car, where you only need to fix the harness and connect the rear lights and fuel level sensor in the gas tank. Tip: Be that as it may, by removing the motor for a bulkhead, the owner has the opportunity to replace the old electrical wiring. I didn’t think much about wiring nuances and differences. On the instrument panel, we power the central head light switch, the emergency gang button, and connect the devices. As a rule, released before 2001, and having carburetor versions of power units, overhaul require Gazelle cars. That is why it is important to have a visual aid on hand when carrying out such an operation, and not a factory one. The fact is that its performance is being checked, that on newer versions of Gazelles, the scheme for connecting certain devices has also changed: After assembling the wiring into a single whole. Equipped with a ZMZ-402 carburetor engine, and when the time comes for a major overhaul, but also about reconfiguring its operation, many owners think not only about restoration, the car successfully develops its motor resource. Laying the wiring harness is not difficult, technological holes that the places of their fastening on the frame were originally provided for gutters, all the more so. Wiring is not listed among the parts to be scheduled for replacement, however, the electrical circuit is quite often required in the implementation repair work V engine compartment. However, not always complete replacement justified, since the repair does not affect other electrical devices other than the ignition and fuel injection system.
performance automotive system ignition (SZ) directly affects the functionality and condition of the engine vehicle. Accordingly, the failure of one of the elements of the system can lead to minor or even serious malfunctions in the operation of the power unit. What is the principle of operation and the procedure for SZ, how to replace the Gazelle ignition switch - read more about this below.
[ Hide ]
The principle of operation of the Gazelle ignition system
To begin with, consider the principle of operation of the SZ Gazelle 402 engine. IN this case we are talking about any models of this car - both with a 406 engine and 5-seater Gazelles. The principle of operation of the SZ lies in the accumulation and further conversion of low-voltage voltage into high-voltage voltage using a coil after that. After conversion, the coil transmits and distributes high-voltage voltage to the candles of the system. The candles themselves are used to generate a spark, which, in turn, is necessary for ignition. air-fuel mixture in cylinders.
The main stages of the work of the SZ:
- accumulation of low-voltage charge;
- converting it to high voltage;
- distribution of momentum on the corresponding candles in a certain order;
- creating a spark on the electrodes of candles;
- combustion of the combustible mixture.
Ignition order
The scheme for connecting the cylinders on the Gazelle, that is, the very order of their activation, for the 406 engine is as follows:
- first, the mixture ignites in the first cylinder;
- then the caviar is served on the third;
- after that - on the fourth cylinder;
- the second cylinder is the last to work.
Basic elements of SZ
Briefly about the main components of the SZ:
- , which includes several coils;
- switching device;
- distribution mechanism;
- candles;
- candle tips;
- elements for connecting candles to a coil - high-voltage cables.
Lock replacement and repair
If nothing happens when you try to turn on the key in the lock, that is, the engine does not start, the problem may lie in the poor connection of the contacts. You can try to repair such a lock, if this does not help, then the device will have to be changed (the author of the video is Sergey Vishnyakov).
Replacing the contact group
Such a task is performed as follows:
- First you need to disconnect the battery, to do this, reset the negative terminal from it. Next, the protective lining of the steering column is dismantled. Using a flat head screwdriver, you will need to remove the two bolts that secure this shroud.
- Having done this, you can dismantle the upper part of the lining.
- Further, the steering column is transferred to the extreme top position. You will need to slightly tilt the top of the trim towards you until the fasteners of this part of the casing come out of the slot.
- Then the lining is dismantled, it must be shifted up.
- Using a flat-tip screwdriver, you will need to unscrew the two bolts that secure the contact part of the lock. Then the contact component is removed and replaced with a new one, further assembly is carried out in the reverse order.
Photo gallery "Changing the contact group"
Changing the lock
To completely change the lock, do the following:
- As in the previous case, you first need to dismantle the protective cover.
- It will not be possible to dismantle the clamp, since regular nuts do not have edges, so it must be cut, for example, with a grinder. Be careful not to damage the steering column tube.
- Next, you need to disable steering column- This is done so that the further replacement procedure is more convenient. First, a long screw connected to the steering wheel height adjuster is unscrewed. After that, the steering wheel itself should be lifted up, this will allow you to unscrew another bolt, for this a 12 wrench is used. When removing the screw, you will need to remember the position of the curly brace, it is located next to its cap.
- The next step is to remove the old ignition.
- Now take a new bracket and make slots in its sides where the caps of the lag screws will be located. The slots are a must as they will allow the four lag screws to be tightened without any problems. In the event that there are no slots, this will lead to the fact that the heads on the ratchet will rest against the edges, so that it will not be possible to securely fix the device.
- Next, the device is placed in the seat, four screws are tightened, they need to be tightened to the maximum. The two 12" nuts you removed earlier do not need to be fully tightened as this will result in you being unable to adjust the steering wheel. Assemble the entire structure and test the operation of the installed lock.
Very often, Gazelle owners, when replacing power units from carburetor versions to injection ones, are faced with the need to replace the electrical wiring in the car, since there are serious differences in the electrical circuit.
However, a complete replacement is not always justified, since the repair does not affect other electrical devices other than the ignition and fuel injection systems.
Accordingly, when planning to replace the engine with a Gazelle, the owners prefer a more modern injection engine, for example ZMZ-4061 or ZMZ-4063.
As a rule, Gazelle cars produced before 2001 and having carburetor versions of power units require major repairs.
Then the 402 motor was often installed, and the Gazelle wiring diagram for the 406 motor, which appeared in production program car factory in 1998, had its own design features, not compatible with different types engines.
The power unit that has exhausted its resource is subjected to replacement, often giving preference to more modern versions.
Structurally, everything rises to the factory seats, and the differences, for example, from the location of the equipment:
- Another form of connecting blocks;
- Another scheme for connecting devices;
- Another voltage.
Supply system
Leaving the carburetor in the past, the replacement of the power unit inevitably entails the replacement of the power system:
- A new gas tank is installed, since the injector must dump excess fuel back, and the old tank design is not suitable for this;
- The fuel line is being replaced (the return line is being laid + the supply connection is being modified);
- The operation of the injectors is controlled by connecting wiring.
Cooling system
The new injection engine ZMZ-406 is more demanding on the cooling system, therefore, during the installation of a new power unit:
- An electric fan is installed on the cooling radiator;
- Wiring harness being replaced engine compartment.
Fuel injection control system
Do not forget that the injection engine power system is controlled by an electronic unit, which also needs to be connected to the car's standard electrical network. Accordingly, the electrical wiring on the Gazelle 406 is different than on older versions of the car with 402 series engines, and must be replaced.
Wiring replacement
Tip: replacing functional control devices on the panel due to new connectors is not justified.
Therefore, when integrating new wiring, only the wiring diagram in the connecting terminals changes, and for alignment, you should use the wiring diagram of the new power unit.
Changing everything to 406 is certainly not impractical.
The fact is that on newer versions of Gazelles, the scheme for connecting certain devices also changed:
- wiring Gazelle 406 is integrated into the standard electrical system in the engine compartment;
- electronic components and control devices are connected using terminals;
- checked with testers voltage and correct connection.
After assembling the wiring into a single unit, its performance is checked. In the future, the operation of the power unit is adjusted.
Conclusions: Replacing the power unit inevitably affects the change in the standard electrical wiring of the car. That is why it is important to have a visual aid at hand when carrying out such an operation, and the factory one will allow you to avoid mistakes.
The electrical circuit of a Gazelle commercial vehicle may differ primarily depending on which one. The wiring is also different according to the type of body - for example, the rear lights are located differently than the onboard one. Accordingly, the wires are laid in a different place, having a different length.
Wiring in the cab of a GAZ 3302 truck
It should also be taken into account different generations cars by year of manufacture - over time, instrument clusters, optics, fuse box, etc. change. Plugs and wiring change in the electrical circuit. Therefore, there are many modifications in the electrical circuit.
Despite many modifications, the principle of building an electrical circuit is the same on all cars. All consumers electrical energy eat from constant voltage 12 volts. The mass of the body and the power unit is a negative wire, the electrical circuit is two-wire.

Various schemes depending on the engine
The very first to be installed on the Gazelle were ZMZ 402 carburetor engines. For the operation of the internal combustion engine ignition system, it was necessary to supply power to the ignition coil, distributor and switch. The next in the series also went in a carburetor version.
But there was already a coil on it, there was no distributor and switch, instead of them it was installed the electronic unit ignition control.
Later, the Gazelles began to be completed injection engine ZMZ 405, which had a distributed injection system instead of a carburetor.
It looks like the ZMZ 405 engine
The engine wiring on this engine is already completely different - the control unit has become common to both the ignition system and distributed injection.
have their own electrical circuit, and it is different depending on the type of internal combustion engine installed: Cummins or UMZ-A274. The Gazelle Next has been equipped with a new 2.7-liter engine since the end of 2014.
Rearranging the engine wiring
Prudently divided the bundles of wiring into the front, rear and engine compartment. Therefore, when changing the power unit to another type of engine (for example, a ZMZ 406 carburetor to a ZMZ 405 injector), it is not necessary to change all the wiring at all, just change the engine compartment wires. 
It is also easy to rearrange the underhood wiring harness in case of ICE replacement 3M3 402 on ZM3 406 carburetor or ZMZ 405 injector.
Everyone's work electrical elements in cars depends on the condition of the electrical wiring and current sources. Owners of domestic commercial vehicles especially useful is the ability to read and understand the electrical circuit of the Gazelle, given the age and condition of many of these machines.

Symptoms
Signs of problems with the electrics of Gazelle cars are failures various systems such as heating systems or alarms. If checking and replacing the fuses that protect this section of the circuit does not help, then the problem lies directly in the wiring. A wiring fault is also indicated by the repeated burnout of the installed new fuse-link.
Typical "symptoms":
- The engine does not start. If the starter does not work and the lamps on the dashboard, then the cause is a dead battery. If the lamps are lit normally, but the starter does not work, then the cause of the problem should be sought in the wiring. When the starter is running and there are no flashes in the cylinders, damage to the electrical circuits of the ignition system may be the cause. You can fix the problem by charging the battery or replacing damaged cells.
- A lit on-board battery charging lamp with a stable engine running indicates problems in electrical circuit generator or open drive belt. Gazelle cars have a voltmeter that measures the voltage in onboard network. The operation of the generator can be judged by the readings of this device. If such problems arise, it will be necessary to replace the belt or overhaul the generator with the replacement of burned-out elements.
- The appearance of a burning smell indicates overheating of the wiring elements, which may occur due to damaged insulation. In this situation, it is necessary to check the condition of the fuses and ring all sections of the circuit with a tester to determine the location of the circuit. Need to replace for repair damaged areas chains and lay them in such a way as to prevent repeated grinding.
- Indicates short circuits in the circuit unstable work lighting devices. If the lamps are too bright or rhythmic pulsation, the cause must be sought in a failed voltage regulator installed on the generator. The regulator is replaced by removed generator. In parallel, you can check the condition of the brushes and the collector.
- Non-working sections of the circuit. This is possible due to oxidation and decay of contacts or wires. In the event of a complete failure of the power supply system, check the condition of the battery and the terminals on it. When the contacts on the battery are oxidized, they cannot transmit high current. At the same time, backlight elements, a radio tape recorder, and wipers can work. But when you try to start all the lights go out. You can fix the problem by stripping and tightening the contacts.
