On Chevrolet Niva SUVs manufactured before 2006, the electrical circuit for switching on the starter was very simple. It included a rechargeable battery, a generator terminal B +, an ignition switch and a starter. The only drawback of this scheme was that if the driver, while the engine was running, accidentally turned the ignition key to the "starter" position, then it worked, and its drive gear tried to mesh with the rotating gear rim of the flywheel, which led to cutting off the tips of the teeth on both gears ... Therefore, since 2006, an additional relay (type 2123-3722-010-22) was installed at the bottom of the mounting block, which blocked (disconnected) the starter when the engine was running.

When, when trying to start the engine, the starter does not work, the driver, in order to determine the location of the malfunction, will need a piece of wire that can be used to connect the positive terminal of the battery to the plug in the connector of the red wire going to terminal 50 of the solenoid relay. You need to look for this connector on the right mudguard. You just need to remember that the cross-section of the wire should not be very small (less than two square millimeters).

If the starter starts working, it means that it is working properly. In this case, you will have to check the contact part of the ignition switch (terminals 30 and 50), and on cars with the year 2006 and later, also the electrical circuit of the additional relay, which is triggered by the command of the ECM controller (BOSH M7.9.7). In addition, on those Chevrolet Niva vehicles where the alarm is installed, it may be necessary to check the ignition lock interlock circuit.

But if the starter does not start working, then you have to look for a malfunction in it. When, when voltage is applied to terminal 50 of the traction relay, you hear a click, it means that its retracting and holding windings are working. If, after clicking, the starter armature does not begin to rotate, then you will have to sequentially check the condition of the battery terminals and the solenoid relay, as well as the collector brushes. Particular attention must be paid to the lower contact of the solenoid relay, since due to loosening of the nut, the contact burns out. To eliminate this malfunction, you will have to unscrew the nut, clean the contact and put everything back in place. But this must be done with the negative terminal of the battery removed.

In order to find a malfunction on the starter, it will have to be removed, but this must be done from the bottom of the car. If there are heat shields that protect the starter from overheating (there is an exhaust pipe next to it), in no case should they be removed, as this will damage the starter.

The condition of the roads and external conditions in our country are such that many people need a car with an all-terrain vehicle. An excellent option that combines a low price and good quality is the Chevrolet Niva. When operating this machine, special attention must be paid to the starter, the rules for its use and repair.

Starter; it is a mechanism that works and moves due to the interaction of magnets. The rated power of this device on the Chevrolet Niva is 1.55 kW. The current strength in it will be:

  • with the development of the boundary power 375A;
  • when braking up to 700A;
  • idling less than 80A.

The starter consists of 28 different parts, including mounts, housing and internal components. The rotation of the armature shaft due to the sintered liners leads to the movement of the drive shaft.This is also facilitated by a gearbox consisting of various gears. They, in turn, are driven by needle bearings. Thanks to the connected battery, the voltage is transmitted directly to the starter, and it starts to move.

Like any mechanism in a car, the starter works very often, which leads to its periodic breakdowns. In order to deal with this, it is necessary to clearly identify the cause, and then eliminate it. Only in this case it is possible to return this system to stable operation at minimal cost. For example, if the starter does not turn, then most likely the reason is the battery. You need to charge it or buy a new one. It may also happen that the battery is in order. Then the reason may be for the oxidation of the wires. In general, on the Chevrolet Niva, problems and difficulties can arise, the solution to which is completely different.

Some problems with the starter can be identified solely by analyzing it when starting the engine.

For example, if after several switching on the traction relay turns off. Such a problem may be caused by an unusable battery (low voltage) or oxidation by the wire. There are times when it is impossible to find out the reason without removing the starter and conducting research on a special stand. Based on the results of such work, a decision is made whether to replace the clutch, gears or something else.

In most cases, on a Chevrolet Niva, problems can be identified as follows. It is necessary to take a current source and an ammeter and connect to the mechanism. After that, turn on the voltage at the level of 12V, periodically changing the braking. Based on the results of the behavior of the device, it will be possible to conclude: disassemble it and inspect each part separately or replace it completely.

Perform full braking tests to effectively determine the cause of the problem and repair (replace) it. It is better to entrust all these works to professionals who can do exactly what is needed. If you have the necessary equipment, then you can carry out the repairs yourself.

When there are any problems with the starter, its removal is considered a mandatory procedure. Moreover, on the Chevrolet Niva, for some other repair work, the removal of this part is necessary, because it will interfere. Using the usual tools that every car enthusiast has, you can dismantle it yourself. The starter is removed in the following sequence:

  1. We disconnect the terminals from the battery to de-energize the car and protect ourselves.
  2. We take the elongated socket head and remove the starter gearbox. To do this, you need to unscrew several bolts with which it connects to the gearbox clutch housing.
  3. We remove the spacer of the exhaust pipe. To do this, you need to remove the fastener at the bottom of the rear strut and move it further.
  4. Dismantle the starter directly. When doing this, be careful not to touch or entangle the wires.
  5. The block together with the supply wire must be separated from the traction relay terminal.
  6. We move aside the rubber cover, remove the nuts, the bolt wire on the traction relay.

After all these steps, you can carry out the necessary repair work. Removing the starter is easy to do, but it only requires careful and careful action. To put the starter in place, you must do everything in the reverse order.

Most starter problems on a Chevrolet Niva vehicle arise from improper use. There are certain rules that you can follow to help prevent problems from occurring.

When you start the engine, the starter should run no more than 15 seconds the first time, and no more than 30 seconds when you turn it on again.

Otherwise, the operation of the starter for a long time may lead to overheating. It is necessary to make no more than 3 attempts to start the engine. If it still doesn't work, then there are other problems.For example, there may be problems with the ignition or with the engine power system.

After you start the engine, the starter must be disconnected immediately. This is explained by the fact that during continuous operation of the drive gear with the flywheel, the overrunning starter clutch can simply jam.

It is imperative that the starter is used only for its intended purpose. Never try to move your car with it. Working in this mode will lead to its significant overload and breakdown in the future.

Every car owner will be familiar with such a situation when the morning started late and you start rushing to work, on business. But it happens that after a night of inactivity, the car simply refuses to start, or starts after numerous attempts.
