6.2.1. Introduction


If the starter does not work in the provision of a key "engine start", the following reasons are possible:

The accumulator is faulty.

Break of an electric chain between the ignition lock, the traction relay, the accumulator and a starter.

The traction relay is faulty.

Mechanical or electric defect of a starter.

For check of the accumulator light headlights. If they grow dull in some seconds, the accumulator means is discharged. Recharge or replace the accumulator. If headlights do not grow dull, include a starter and watch light. If they grow dull, means, tension arrives to a starter and malfunction is in it. If headlights continue to burn brightly (and there is no click of the traction relay of a starter), it specifies that there is a damage to an electric chain or the traction relay is faulty. If the starter rotates slowly, and the accumulator in a good condition, it specifies that the starter is faulty or there is a considerable resistance at an electric chain of a starter.

If damage to an electric chain is suspected, disconnect the accumulator and clear all connections and contacts in a starter power-supply circuit. Repeatedly connect the accumulator and, using the voltmeter, check tension on elements of an electric chain to a starter.

If the accumulator and an electric chain in a good condition, remove a food wire from the traction relay and connect to it the voltmeter. Turn the ignition key in situation "engine start". In this situation there should be a full tension of the accumulator.

Contacts of the traction relay can be checked by voltmeter connection between contact of the traction relay connected to a starter and the earth. At ignition key turn in situation "engine start" the voltmeter should show tension. In the absence of tension the solenoid of the traction relay is faulty or contacts of the traction relay scorched.

If the electric chain and the traction relay are serviceable, means the starter is faulty.
