Advantages of installing a three-level regulator

The three-level voltage regulator on the VAZ 2107 is capable of maintaining a constant voltage supplied by the generator to the vehicle network.
With this product it is possible to save and increase the battery life. In addition to regulating voltage, three-position regulators are capable of maintaining current within a certain range. Some of the main advantages of the device in question include:

• The main board of the device is located not in the generator itself, but away from it, which contributes to less heating of the product, as well as extending its service life.
• Possibility to regulate the voltage level manually thanks to a special switch. The device operates from a switch.
• The charge level is significantly higher, in contrast to standard products.

Problems with starting the engine, especially on frosty days when it is very difficult for the starter to start the engine, can be avoided by replacing the standard device with a three-position one. Large loads on the electrical circuit in a car, such as headlights, heater, heated glass, can contribute to battery discharge, even if the engine is running and the standard product is in good working order.

Types of regulator relays are simple, three-level and with temperature compensation. In the brush section of a standard seven generator, in most cases, a temperature-compensated option is installed. But, as practice shows, in terms of thermal regulation, these regulators are mostly ineffective. Recently, among drivers of the VAZ 2107 and other Lada models, the three-level type is gaining more and more popularity. Car owners who have installed such a regulator overwhelmingly recognize it as more effective than the standard one.

Characteristics of the Energomash device for VAZ 2107

The Energomash voltage regulator for the VAZ 2107 is equipped with three “25C” type diodes and a mode switch. With their help, a three-stage voltage change is carried out. A three-level balancer is also called a current injector, since the device is capable of maintaining it at a level of up to 6A. The main functionality of the three-level voltage regulator for the VAZ 2107 model "Energomash" is based on changing the current from the generator, thereby increasing the voltage of the on-board circuit to 13.6-14.7 V.

The first operating mode provides for maintaining the voltage at the generator output at 13.6 Volts. The switch should be installed in a position where the ambient temperature is +20 degrees and above. The switch in the neutral position should be set at temperature values ​​from 0 to +20 degrees. And in the third position, the generator will produce a voltage of 14.7 V when the air temperature is from 0 to -20 degrees.

Changing the brush assembly

Replacing a standard product with a VAZ-2107

Connecting a three-position regulator, or rather, changing a standard product, does not present any difficulties. After purchasing the product, you must complete the following steps:

1. Initially, you need to remove the protective cover of the generator. Don't forget to disconnect the negative terminal from the battery.
2. The standard part is removed by unscrewing two bolts using a screwdriver or a “6” key, which depends on which VAZ generator is installed on the car. It is also necessary to remove the terminal.
3. After this, we compare the standard device with the three-level one. The brushes and fasteners must be identical in design, otherwise the product will need to be replaced.
4. A new product is installed in place of the standard “tablet”, after which it is fixed with fasteners (bolts).
5. The body of the product should be secured to the ground of the car in any convenient place (pictured below). This is not difficult to do, since the wire is long enough.

After installing such a product, the owner of a VAZ-2107 car will be able to forever forget about constant problems with a dead battery, since the new regulator will recharge it more stably under certain temperature conditions.

Diagnostics of the relay voltage regulator of the generator VAZ 2109Post navigation

• Keys 10, 17, 19;
• Set of heads;
• Ratchet;
• Mount;
• Hammer and punch.

First, remove the chips from the generator. The wire to terminal “30” is secured with a nut; unscrew it using a 10-mm open-end wrench; Using a 17 key, loosen the adjustment bar and press the “gene” to the cylinder block. Usually this can be done by hand, if it doesn’t work, use a pry bar. Remove the belt; We remove the adjusting bar; to do this, unscrew a pair of 17 nuts. In extreme cases, it is enough to dismantle only the nut that is on the generator itself; Unscrew the nut 19 from the generator mounting screw. It is most convenient to use a ratchet for this; Gently tap the end of the screw to move it out of place. Next, hit the head of the screw to knock it out. In the end, you will have to support the generator, otherwise it will warp and the screw will jam; We remove the generator. It is pulled down, between the bracket and the cross beam. Installation is carried out in reverse order

At the same time, pay attention to the installation and tension of the belt: Install the adjusting bar, the fastening screw should not be tightened; Place the belt on the pulleys; Using a pry bar, press the generator away from the engine until the belt is fully tensioned. Holding the part in this position, tighten the fastening nut.

• The wire tip is removed from the relay output;
• A pair of mounting screws are unscrewed; for this you will need a Phillips screwdriver;
• The relay is removed along with the brush holder. At the same time, inspect the condition of the brushes. If they are shorter than 10 mm, or one is noticeably smaller, then the relay should be replaced. The brushes cannot be changed separately;
• To check, terminal “B” is supplied with power from the positive of the battery, and negative is supplied to ground. After that, we check the voltage on the brushes, it should remain within 13-13.5 V without twitching.

Diode rectifier

Two signs of diode bridge failure:

• No battery charging.
• The charge is much higher than expected.

This breakdown can lead to quite negative consequences. If you doubt your abilities, it is better to entrust generator repair to a person who specializes in this. Most often, two diodes fail, but replacing them is problematic, since these spare parts for generators are not sold separately. It will be much easier to buy a new one and install it. Replacement is carried out in the following sequence:

• A contact bolt with bushings and nuts is installed in the block, and clamping is performed.
• Correct and reinstall all leads of the stator windings, tighten the nuts for their connection.
• Reinstall the bolts that secured the rectifier unit. Tighten them.
• Install the relay-regulator and tighten its mounting bolts.
• Install the plastic casing and secure it with the latches.
• Install the generator on the car, tighten the belt and check the operation.

Mechanical and electrical breakdowns

This malfunction manifests itself in an increase in the noise level emitted by the generator set. The reason is the destruction of one of the bearings. As a rule, the one that is located in the front cover - it is subject to very large loads, especially when the VAZ 2114 generator belt is tensioned too much. For this reason, you should always monitor the tension of the generator drive belt.

As for breakdowns in the electrical part, they can manifest themselves in the form of a lack of battery charging voltage or its low (sometimes too high) value. To check the serviceability, it is not necessary to remove the generator from the car. To do this, use a multimeter. Take voltage measurements at the terminals of the VAZ 2114 battery. The generator should produce about 14 Volts when operating. If it is 12 Volts or lower, then the generator is not producing the required voltage and needs to be repaired. In some cases, the fault lies with the voltage regulator or worn brushes.
