7.7.2. Check of system of ignition


The prevention

Observe the security measures excluding electric defeat. Before joining of devices disconnect ignition.


CARBURETTOR ENGINES WITHOUT NEUTRALIZER

Ignition refusals, as a rule, are caused by pollution of contacts or breakdown on a surface.

Ignition check by a consecutive detachment of high-voltage wires is forbidden.

PERFORMANCE ORDER
1. At start-up refusal first of all check up pressure of the battery at starter inclusion, having disconnected and having connected to weight a high-voltage wire of the coil. If pressure less than 9,5 In check up the battery and charge system.
2. At normal turns of a starter connect a stroboscope and define pressure presence on candles. If stroboscope flashes it is necessary to check up candles are observed. Otherwise check up a condition of wires, covers of the distributor, a piece of coal and бегунка.
3. If there is a spark check up the carburettor.
4. In the absence of a spark check up pressure on a conclusion "+" coils (11,7). If pressure more low 11 In check up all feed circuit, including a safety lock and connections with weight.
5. If pressure normal check up the ignition coil (resistance of windings, reliability of contacts, especially low-voltage).
6. If the coil is serviceable, the electronic switchboard (is checked and under repair in car-care centre) is faulty.
7. Check up the thermovacuum valve. Disconnect демпфирующий the valve and blow, – air should pass freely from outside the distributor.
8. If the engine works with faults check up low-voltage and high-voltage chains.
9. Check up reliability of contacts and resistance of a primary chain.
10. Check up a condition of a cover of the distributor, candles (by their mutual substitution), бегунка and a piece of coal.
11. Check up a stroboscope pressure presence on all candles and wires.
12. In the absence of pressure on a part of wires it is necessary to check up wires or a distributor cover.
13. At a high voltage total absence check up the ignition coil.

CARBURETTOR ENGINES WITH NEUTRALIZER AND ИНЖЕКТОРНЫЕ ENGINES

PERFORMANCE ORDER
1. At refusal of system of ignition it is necessary to check up a condition of the air filter, candles, cable adjustment заслонки, a compression and backlashes in valves.
2. Check of system of ignition of these engines is reduced to definition of a corner of an advancing, check of reliability of sockets on the block of management and fastening of wires.
3. On инжекторных engines it is necessary to use a self-diagnostics mode.
4. If malfunction is not found out, it is necessary to hand over the car in car-care centre service.
