R2 –51 Ohm, (5 W).

Characteristics of the standard generator

The main characteristics of the generator installed by the manufacturer in Niva 21214, 21213, 2121 will be considered using the example of generator type 9412.3701:

current – 80A;
voltage – 13.2 V,
rotation is right.

The cost of standard models of electric generators is 5-7 thousand rubles. If the unit breaks down, it is possible to replace its components or completely replace it with the original or analogues. The prices of the most common ones are presented in the table.

Analogue	vendor code	Cost, in rubles
Generator VAZ-2104-21073,21214	9412.3701-03	5900
Generator VAZ-2104-21073,21214	372.3701-03/05	3800
Generator VAZ 2121-21213,21214	9412.3701	5450

The table shows that in the process of replacing a generator on a Niva, you can give preference to a cheaper universal analogue.

The second ends of the black wires are also brought together to a point connected to ground. The second ends of the yellow wires with a blue stripe are brought together to a point connected to terminal “A” of the main fuse block. And the second ends of the orange wires are also brought together to a point connected to terminal “B” of the main fuse block.

* Installed on parts of manufactured cars; **not installed since 2000; *** installed since 2001. Previously, the rear fog light was switched on directly by switch 47, powered by fuse 3 of the additional fuse box.

Generator faults

During the operation of any car, unpleasant situations often arise in the form of failure of one or another element. Niva is no exception, and most often the generator suffers.

If the generator seems to be faulty, it is recommended to check its functionality using a multimeter. To do this, you will need to start the engine and check the voltage at the battery terminals. The standard value that a multimeter should read is 13.6 V.

If the readings during measurement are higher, it means that a break or short circuit in the windings has occurred in the structure. The same can be said about the case when the voltage is below the specified number. This procedure is carried out regardless of the engine: injector or carburetor.

Also, if the breakdown is caused by another reason, you can replace the generator itself. Usually, for replacement, they turn to special service stations, but if necessary, the work can be done with your own hands.

How to use the interactive wiring diagram

If you hover your mouse over the greenish circle located next to a diagram element, the name of the element pops up.

To see which pins are connected, click on the slightly shaded rectangular area near the end of the wire or where the wire meets the connector it is connected to, which will animate the wire according to the current flowing through it. The mouse pointer changes appearance when hovering over such an area. To turn off the animation, click again.

To enlarge the image, right-click and select the “enlarge” menu item. To return the image to its original scale, select the “show all” menu item.

Generator replacement

To repair or replace the generator, the car owner will have to remove the unit completely from the car or turn to professionals for work. If you still want to carry out the replacement yourself, then first you will need to prepare all the necessary tools:

hammer;
extension;
keys to "10" and "19".

The procedure consists of the following sequence of actions:

First, you will need to park the car in a place designated for inspection and repair. The car will also need to be secured using special wheel chocks. Finally, in order for the work to be carried out safely, you should disconnect the battery by disconnecting the terminals from it.
After this, you need to remove the engine protection. It is attached to several bolts, and they must be unscrewed to get to the lowest bolt of the generator.
After this, you will need to knock out the mounting bolt using a hammer. It is recommended to knock carefully so as not to damage the thread and to prevent the bolt from coming out in the opposite direction. A hammer is necessary, since a wrench or any other tool simply cannot handle a bolt.

Next, you need to remove the bolt, swinging the generator from side to side. It is necessary to bolt in any case, as this makes it easier to remove the rod.
The fourth step involves disconnecting the wiring. To do this, the power wires connected to the housing are disconnected from the unit. In this case, you can first disconnect the plug from the wires.

Wires are also attached to the generator, tightened with a nut or bracket. In this case, the nuts must be unscrewed with a wrench, and then the loose wires must be pulled out.

Finally, after disconnecting the wires, you can begin to unscrew the upper fastening element with the belt tensioner. For this you will also need a wrench, as well as a small extension cord.

Disconnecting the fastener will allow you to remove the belt and alternator. Then you can start cleaning the vacated space with a brush and installing a new unit.

The structure is assembled in the reverse order; the entire procedure will take about two hours if you have all the necessary tools.

Additionally, it is worth noting that when everything is assembled, you will need to adjust the position of the generator using the tensioner. To do this, you need to unscrew the tensioner nut and tighten or loosen the belt, while observing the battery charge.

If the indicator returns to normal, then the selected tension is sufficient. There is no need to tighten the structure, as the generator bearing may fail. If the tension is insufficient, the generator will work intermittently, and this can also lead to breakdown.
