Starter VAZ-2115: possible malfunctions

VAZ-2115 is truly a national car. It was released serially for more than ten years. Its popularity has gained thanks to a simple device and low cost of maintenance. However, nothing lasts forever. And sometimes such a reliable detail, like a starter, malfunctions. The machine can not be started. What to do in this case? How the VAZ-2115 starter is arranged, troubleshooting and methods for their elimination are discussed later in this article.

Characteristic

In any car, an ignition system is provided. However, it is not only candles, coils and armored wires. This system includes a starter. VAZ-2115 is also equipped with them. On cars "Samara-2" it is gear-type. The element is assembled with the traction relay and the drive mechanism. The starter interacts with the ignition lock and the engine, being an intermediate link. The main purpose of the element is to create the necessary torque for the engine, which will give the engine an opportunity to work independently.

Device

The starter VAZ-2115 consists of the following elements:

• Stator.
• Rotor (anchor).
• Contact plate.
• Brushes with holder.
• Traction relay.
• The mechanism of the drive.

Power to the windings of the starter is via the traction relay. So, when you turn the ignition key from the battery, there is an inrush current (of the order of 500 amperes) to the relay. Then this mechanism moves the drive element. The gearing includes the driving gear of the starter and the cogwheel of the flywheel. A few revolutions are enough for the unit to successfully start (of course, if you have a working starter). VAZ-2115 has a simple device of this element. However, do not exclude malfunctioning with it. So, let's look at why the VAZ-2115 does not start a starter and what to do about it.

Do not twist at all

If, when the ignition is switched on, the armature does not rotate and the traction relay does not operate, check the voltage in the battery. A successful start requires at least 12 volts. The starter battery takes a lot of energy. Therefore, it is so important to keep it in good order. There are several ways to check the voltage on the battery. The best method is a multimeter. When you close the contacts on the device, the result is displayed. But if there is no such device, and there is no voltage indicator on the panel, you can use the grandfather method. To do this, take a 12-volt automobile bulb and a pair of wires. With bare contacts it is closed at the terminals. If the voltage is 12 volts, it will light up properly. If less, it will be very dim.

The next reason why the traction relay does not turn on is the slightly tightened wire tips (both from the battery side and from the starter side). Perhaps there are oxidized contacts. Use a special cleaner or sandpaper. Specialists do not exclude a break in the retracting winding. If the cleaning of the contacts did not help and does not turn the starter, the VAZ-2115 requires replacement of the traction relay. How to do this, consider at the end of the article.

The anchor rotates slowly, the relay does not work

What if the car VAZ-2115 does not start, the starter turns and does not "grasp"? In this case, it is required to clean the wire retention nuts. If this did not help, we can say that the collector is ignited or the brush assembly is worn out. In this case, the brushes are to be replaced. The anchor breakage is not excluded. It changes entirely to a new one.

The relay trips, but turns off

In this case, there is a strong voltage drop in the power circuit of the traction relay. Check the condition of the circuit from the battery to the plug "50" on the VAZ-2115. The relay itself is correct - it is important to find where the contact periodically disappears. Again check the clamping level of the terminals on the starter. In most faults, the cause is bad contact.

Anchor rotates, flywheel - no

In this case, the reason is that the free-wheel clutch slips. It is required to disassemble the starter and inspect its state visually. If necessary, replace the gears of the reducer.

Noise when rotating the armature

In this case, check the condition of the bearing shells of the drive shaft and the armature. Replace the worn out items. Probably, the starter fastener is loose or its cover is broken at one end. Because of this, the mechanism works counter-clockwise. Examine the flywheel. On its teeth there should be no working out. If it is available, the flywheel must be replaced. It happens that the gear does not go out of gear with it. In this case, the cause of the malfunction is malfunctioning. It seizes on the splines of the shaft. The starter relay VAZ-2115 can work normally. Clean the splines and treat them with oil. This helps to eliminate galling.

How to change the relay yourself?

To do this, we need to de-energize the on-board network - remove the terminals from the battery. Next, clean the surface of the starter from dust and dirt. Unscrew the nut from the relay and remove its contact. Unscrew bolts of fastening of the relay to a starter body. After that, remove the nut from the end.
Further it is required to dismantle the old core and put a new one in its place. All elements are assembled in the reverse order. It is important to check the operation of the new device immediately after repair. We install the starter into place, pump the terminals and start the engine. The motor should start with a half-turn (under the condition of a normally-charged battery).

What else do you need to know about the relay?

Since the starter consumes a sufficiently powerful current, the integrity of its elements must be checked every 100 thousand kilometers or every 3 years. During this time in the mechanism there may be slight fluctuations in the voltage, because of what the relay can fail.
You can check its functionality by a typical click. It happens that when you start the starter continues to work. In this case, you will hear a sharp squeal. This indicates that the retractor is out of order. The mechanism can not return to its opposite position.

Conclusion

So, we found out how the starter works on the VAZ-2115, what are its malfunctions and how to eliminate them. This element must always be in working order. In case of any malfunctions, a complete diagnosis must be made. Otherwise it will be possible to start the engine only "from the pusher", which is not always possible.
