The starter is an indispensable element of the launch system of each car. By its design, it is a kind of direct current source, which spins the crankshaft to those revolutions that are needed to start the internal combustion engine. And if your iron horse suddenly stopped starting, then the source of the problem should be sought in this part. But not always after detecting a breakdown, this spare part should be replaced. Perhaps the breakdown is hidden in the battery or in individual starter elements. But how exactly to find the exact source of trouble and what to change in such a situation? You will find answers to these questions in our article.
Before listing the breakdowns, I would like to note that the starter on the VAZ 2109 has a similar design with all the "Lada" models 2104-2107, so this instruction will be useful to all owners of domestic VAZs.
Causes and troubleshooting
The first thing motorists may encounter is when, when turning the ignition key, the motor traction relay and starter armature do not work.
There are several reasons and solutions for these problems. Firstly, it may indicate a faulty or discharged battery. In this case, charge or replace the battery. Secondly, damage can be hidden in the oxidized terminals of the battery or in untwisted tips. The way out is to clean the battery terminals from dirt. Also remove the tips, grease them and tighten them again. There are breakdowns in the relay, and more precisely in its winding. In this case, the only way out of the situation may be to replace this part.
The second case - the VAZ 2109 starter works, but with constant noise.
There are three reasons for this. The first is the failure of the necks of the armature shaft or bearing bushings. In order to resume the operation of the VAZ 2109 engine, the starter must be completely replaced. The second reason may be hidden in the broken cover of this part or its loose fastening. There is no need to change anything, you just need to tighten the nuts that fasten the starter VAZ 2109. And the last reason is the skew of this part. This means that the starter during installation was not properly fixed. To fix the problem, check the reliability of all fasteners. If this part is really skewed, you need to remove it and reinstall it according to the rules.
The third case - when starting the motor, the VAZ 2109 starter does not work well or does not rotate at all (while the relay works
OK).
Failure should be sought in the poor contact of the retractor relay connections . If there are traces of dust or oxidation, therefore, it is necessary to clean the compounds of dirt and grease them with Lithol. If the contact is free of clogging, the problem may be with 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, if necessary, replace them with new ones. It is also worth noting that the VAZ 2109 starter will only work when this part has free play, that is, does not hang.
