Starter terminals:
1 - from the positive terminal of the battery (30);
2 — from the starter relay (50).
Note: The starter ground connection is made through the gearbox and cylinder block.
The starter is a DC motor that uses a permanent magnet.
Checking the starter
If the carbon brushes and springs, commutator or starter windings are faulty, the starter will not be able to operate at full power.
The cause of failure of starter components may be:
- excessive wear of carbon brushes and springs;
- high resistance due to heavy contamination of the collector;
- short circuit in winding;
- a faulty bearing causing the rotor to rub against the poles.
Starter design:
1 - drive cover;
2 - gear;
3 - stator magnet;
4 — battery terminal;
5 - rear end and bearing;
6 - Carbon brush holder and carbon brushes;
7 — collector;
8 — rotor;
9 - permanent magnet;
10 — rotor body;
11 - planetary mechanism;
12 - lever with freely rotating clutch;
13 — drive gear engagement block.
Check the starter holders, springs and carbon brushes for wear.

Check the starter commutator for contamination.
Check the starter bearing for play.
If the listed faults cannot be detected, replace the starter.
