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. |
