Diagnostics of malfunctions of a starter without its removal from the car

Before starting starter diagnostics make sure that the battery is completely charged.

If the starter does not join in general, make sure that the selector lever is established in correct position (Р or N) (АТ), or the coupling pedal (РТ) is squeezed out.

Make sure that the battery is charged, and plugs and tips of all wires (on the battery and the traction relay) are not damaged by corrosion and reliably fixed.

If the starter rotates, but does not scroll the engine, it speaks about proslipping обгонной муфты in a starter and necessity of replacement of the last.

If after inclusion the starter does not start to rotate, but the click published at switching of the traction relay is clearly audible, the problem is covered in malfunction of the battery, infringement of contacts or failure of the starter (if the engine certainly is not jammed).

If плунжер the traction relay does not click, being switched at starter inclusion either the battery is faulty, or the fusible insert (rupture in a chain) has fused, or defect of the relay takes place.

 PERFORMANCE ORDER

    For check of serviceability of the relay connect a wire from the complete set for start of the car from an auxiliary source between positive (+) the plug of the battery and the small plug of a wire of the lock of ignition on the relay. If now the starter joins, the relay is perfectly in order also a problem in malfunctions of the lock of ignition, the switch of the permission of start, the start or electroconducting relay. Find the start relay in power supplies centre value of distribution. Take out the relay and make its check (Check of pressure of fuel and functioning of the fuel pump of the Head of the Power supply system and release of the fulfilled gases is absolutely similar to check of relay ASD and the fuel pump in Section (illustrations "see also Measure resistance between plugs 86 and 85..." And "Also measure resistance between plugs 30 and 87А..." In the Head of the Power supply system and release of the fulfilled gases).

Site of centre value of distribution of power supplies (marksman).

Site of the relay of start.

    If the starter on the former does not rotate, remove it together with the relay for carrying out of dismantling, detailed diagnostics and repair/replacement. If the starter turns the engine too slowly, first of all check up level of a charge of the battery and a condition and reliability of fastening of all клеммных connections. Partial jamming of the engine or refuelling by its oil of too high degree of viscosity also can be at the bottom of slow it проворачивания a starter. Start the engine and allow to it to get warm to normal working temperature, then disconnect a wire of the coil from a cover of the distributor and earth it on weight of the engine. Connect a positive wire of the voltmeter to the positive plug of the battery, and negative - to negative. Turn the engine and consider voltmeter indications. Do not include a starter continuously more than for 15 seconds. The indication from above 9 In at a starter rotating with normal speed is considered norm. If an instrument reading above 9 In, but speed проворачивания is insufficient, it is necessary to check up a condition of contacts of the traction relay or electric sockets of a contour. If pressure more low 9 is fixed In and speed of rotation is insufficient, the starter most likely is faulty.
