At starter inclusion the electric motor of a starter does not work

Failure of a starter or the traction relay can be the reason, and also defect can be in wires.

For failure detection at first it is necessary to check tension existence on the plug of the traction relay. Lack of tension at inclusion of a starter testifies to damage of an electric chain, and in the presence of tension, about malfunction of the traction relay or a starter.

If at starter inclusion tension moves on the traction relay, but it does not work (is not present is characteristic click) then the traction relay (break of a winding or its short circuit on weight is faulty).

Existence of characteristic click of operation of the traction relay testifies to a podgoraniye of contacts of the relay or about failure of the starter.

To check operation of the electric motor of a starter it is possible short-term giving of tension, an additional wire of big section on contact of the traction relay from the electric motor. If the electric motor starts to work, means a cause of defect it is necessary to look for in the traction relay.

The starter rotates slowly and does not start up the engine

The reasons can be: the discharged accumulator, too dense oil in system of greasing of the engine, graphite brushes are insufficiently pressed to a collector of the electric motor of a starter, a bad condition of a working surface of a collector and starter bearings are worn-out.

At an ignition key otpuskaniye from situation «engine start-up» the starter continues to work 

The reasons can be: a zalipaniye of contacts of the traction relay or malfunction of the lock of ignition at which it does not disconnect a starter chain.

In this case it is necessary to switch off immediately ignition and to disconnect the storage battery, then to eliminate malfunction.
