Starter VAZ-2115: possible malfunction

The VAZ-2115 - a truly people's car. It was produced commercially for over ten years. Its popularity this car has found a simple and low cost maintenance. However, nothing lasts forever. And sometimes such reliable detail, as the starter is faltering. The car cannot start. What to do in this case? How does the starter VAZ-2115, fault finding and Troubleshooting – further in our article.

Characteristics

In any car provided by the ignition system. However, it is not only the spark, the coil and buenaposada. This system includes the starter motor. VAZ-2115 is equipped with them, too. Cars "Samara-2" it is the geared type. Item comes complete with solenoid and drive mechanism. The Starter communicates with the ignition / engine being somewhat intermediate. The main purpose of the element – to create the necessary torque for the engine that will give ice the ability to work independently.

Device

The starter VAZ-2115 is composed of the following elements:

• Stator.
• Rotor (anchor).
• Contact plate.
• Brush with holder.
• Solenoid.
• The drive Mechanism.

Power to the coil side of the starter is carried out through the traction relay. So, when you turn the ignition key from the battery goes to the start-up current (about 500 amps) for the relay. Further, this mechanism moves the drive element. In the meshing part of the pinion of the starter and gear wreath of a flywheel. Quite a few revolutions that the unit has started successfully (of course, if you have a serviceable starter). VAZ-2115 has a simple device for this element. However, we should not exclude faults with it. So, let's consider why the car VAZ-2115 will not start the starter and what to do about it.

Not spinning at all

If the ignition is turned on, the armature does not turn and does not fire solenoid, check voltage at battery. For a successful launch requires at least 12 volts. On the starter the battery gets a lot of energy. Therefore, it is important to keep it in good condition. Check the voltage on the battery in several ways. The best method – it is a multimeter. With the closure of the contacts on the device displays the result. But if there is no such apparatus, and the voltage indicator on the panel, you can use the old-fashioned method. To do this, take the 12-volt car bulb and a couple wires. Exposed contacts it will short the terminals. If the voltage is 12 volts, it will light up as it should. If less, it will be very dimly lit.

The Next reason does not turn on solenoid is loose the wire lugs (from both the battery and the starter). There may have oxidized contacts. Use a special cleaner or sandpaper. Experts do not rule out an open in the pull winding. If cleaning the contacts did not help, and not spinning the starter VAZ-2115 requires replacement of the traction relay. How to do it, consider at the end of the article.

Anchor rotates slowly, the relay does not work

What if the car VAZ-2115 does not start, the starter turns and not “grasps”? In this case you need to clean up the mounting nuts on the wires. If that doesn't work, we can state the burning of collector or wear of the brush unit. In this case, the brushes must be replaced. It is not excluded and breakage of the anchor. It changes entirely to a new.

The Relay is activated but is deactivated

In this case, there is a strong voltage drop in the power supply circuit of the traction relay. Check the status of the circuit from the battery to the plug “50” on VAZ-2115. The relay itself regularly – it is important to find out where periodically loses contact. Again, check the level of the clip terminals on the starter. In most faults the cause is poor contact.

The Anchor rotates, the flywheel – no

In this case, the reason is a slipping clutch. You need to disassemble the starter and inspect its condition visually. If necessary, replace gear reducer.

The Noise during the rotation of the anchor

In this case, check the condition of the bearings of the drive shaft and armature. Replace the worn parts. Maybe loose starter or its cover is broken at one end. This mechanism works naperekos. Inspect the flywheel. His teeth should not be output. If any flywheel must be replaced. It happens that the gear is out of engagement with him. In this case, the cause of the malfunction in the clutch. She jammed on the splines of the shaft. Starter relayVAZ-2115 it may work fine. Clean the splines and coat them with oil. This helps to eliminate binding.

How to change the relay with your hands?

For this we need to disconnect the on-Board network – remove the terminals from the battery. Next, clean the surface of the starter from dust and dirt. Remove the nut from the switch and remove the contact. Remove the bolts securing the relay to the body of the starter. Now remove from the end nut.
Then you want to dismantle the old core and in its place put the new. All items are collected in reverse order. It is important to check a new device immediately after the repair. Set starter into place, pumped up the terminals and start the engine. The motor will start with a half-turn (assuming a normally charged battery).

What else you need to know about relay?

Since the starter consumes a sufficiently powerful current, the integrity of its elements shall be made every 100 thousand kilometers or every 3 years. During this time, the mechanism may occur slight fluctuations in voltage, causing the relay to fail.
To Check its operability is possible by the characteristic click. It so happens that when running the starter continues to run. In this case, you will hear a sharp squeal. This suggests that the retractor failed. The mechanism cannot return to its reverse position.

Conclusion

So we figured out how the starter on the car VAZ-2115, what are its faults and how to eliminate them. This element must be always in working condition. If any faults need to make a complete diagnosis. Otherwise starting the engine will only be “bump” that is not always possible.
