Starter VAZ 2109 - breakdown, their causes and solutions

The starter is an indispensable element of the launch system of every car. By its design, it is a kind of DC source, which untwists the crankshaft to the speed needed to start the ICE. And if your iron horse suddenly ceased to start, then the source of the problem should be looked for in this detail. But not always after detection of breakage it is necessary to replace this spare part. Perhaps the failure is concealed in the battery or individual elements of the starter. But how exactly to find out the exact source of troubles and what in such a situation to change? The answers to these questions can be found in our article.

Before listing the damage, I want to note that the starter on the VAZ 2109 has a similar design with all the "Lada" models 2104-2107, so this manual will be useful to all owners of domestic VAZ.

Causes and Troubleshooting

The first thing that motorists can face is when the engine's traction relay and the starter's anchor do not work when the ignition key is turned.

The reasons and options for solving these problems are several. First, it can talk about a defective or discharged battery. In this case, you should charge or replace the battery. Secondly, the failure can hide in the oxidized leads of the battery or in unscrewed tips. The output is to clean the battery terminals from dirt. Also, remove the tips, grease them and re-tighten. There are breakages in the relay, or more precisely - in its winding. In this case, the only way out of the situation may be to replace this part.

The second case - a starter VAZ 2109 works, but with constant noise.

There are three reasons for this. The first is the failure of the shafts of the armature shaft or the bearing bushes. In order to resume the engine VAZ 2109, the starter must be completely replaced. The second reason may be hidden in the broken cover of this part or its weakened fastening. There is nothing to change, you just need to tighten the nuts that the starter VAZ 2109 is fastening. And the last reason is the skewing of this part. This means that the starter was incorrectly fixed during installation. To fix the problem, check the reliability of all the fasteners. If this part is really skewed, you need to remove it and reinstall it according to the rules.

The third case - when the engine starts, the VAZ 2109 starter does not work well or does not rotate at all (with the relay running Regularly).

The breakdown should be sought in the poor contact of the retractor relay connections . If the place has traces of dust or oxidation, therefore, you need to clean the connections from dirt and lubricate them with Lithol. If the contact does not have clogs, it may be that the source of the problem is worn brushes or a burnt collector. In this case, clean all collector pads with gasoline. If this does not help, you need to completely replace this part. The same actions are performed with brushes - remove, inspect them and change them to new ones, if necessary. It is also worth noting that the VAZ 2109 starter will only work when this part has a free stroke, that is, do not hang.
