The structure of system of electrostart-up of the engine includes the storage battery, a starter, the traction relay, the ignition switch, the switch of blocking of a starter (only on cars from AKP), connecting wires and wires of the storage battery.
At ignition key turn in the provision of start-up of the engine the current of the storage battery moves in a winding of the traction relay of a starter. Thus there is a shift of an anchor of the traction relay and the lever of a drive of the coupling of a free wheeling, the gear wheel of a drive enters into gearing with a gear wreath of a flywheel. Contacts become isolated and the starter electric motor turns on.
Existence of the coupling of a free wheeling protects a winding and an anchor collector from a rating.

Check of the coupling of a free wheeling
Holding a hand the case of the coupling of a free wheeling, rotate a drive gear wheel. The gear wheel should rotate smoothly in one party and should not rotate to the opposite side.
If the coupling works incorrectly, replace it.
Check a drive gear wheel on existence of wear or задиров on teeths. In the presence of wear or задиров replace the coupling of a free wheeling assembled. At damage of a gear wheel of a drive check also gear wreath of a flywheel on existence of wear or задиров on teeths.

Check plugs on existence of wear or задиров on friction surfaces. At their detection replace a cover from a drive or a collector.
Cleaning of details of a starter
Do not wash out a detail immersion in solvent as it will lead to damage of a winding of a stator, the traction relay and/or an anchor. These details should be cleared only rubbing by a fabric.
Do not immerse in solvent a starter drive. Solvent will wash away the greasing put in the coupling of a free wheeling at assembly.
Clear a drive a brush moistened with solvent, with the subsequent rubbing by a fabric.
Replacement of brushes and springs of brushes
Replace worn-out or greasy brushes.
At replacement of a brush of a winding of excitement break a worn-out brush nippers, trying not to damage a brush wire.
Smooth out the end of a wire of a brush a skin for providing the reliable soldering.
Insert a brush wire into an opening of a new brush and solder it. Track that the wire did not act and on a surface of a brush there was no surplus of solder.
At replacement of a "minus" brush take out a brush from a shchetkoderzhatel, having wrung out holding spring.
