GENERAL INFORMATION

Prevention

At work on ignition system it is necessary to be careful with the included ignition, as it is possible to receive blow a current from a high-voltage part of system of ignition. People with stimulators of warm activity are not recommended to check and make repair of system of ignition. Switch off ignition before a detachment or connection of any element of system of ignition or щупов the measuring device.


The main malfunctions of system of ignition are caused by easing or oxidation of contacts, or short circuit on mass of a high voltage because of pollution, humidity or damage of isolation of high-voltage wires. Before drawing a conclusion on malfunction of any element in ignition system, check a condition of wires or electric chains of system of ignition.

THE ENGINE IS NOT STARTED

PERFORMANCE ORDER
1. If at engine start the cranked shaft of the engine is not turned or turned very slowly, check a condition and a battery charging and a starter.
2. Connect щупы the voltmeter to plugs of the accumulator and disconnect the central high-voltage wire from a cover of the distributor of ignition and connect it to weight.
3. Include a starter no more than for 10 seconds and measure tension on the accumulator.
4. If at starter work tension becomes less, than 9,5 In, check an accumulator condition, a starter and charging system.
5. If at engine start the cranked shaft rotates with normal speed, using a stroboscope, check a high-voltage part of system of ignition.
6. If at engine start the stroboscope blinks, means, the high voltage moves to spark plugs and it is necessary to check a condition of spark plugs.
7. If the stroboscope does not blink, check the central high-voltage wire going from the coil of ignition to a cover of the distributor, coal contact and a distributor rotor.
8. Also existence of a spark can be checked, having removed a high-voltage wire from a spark plug and having fixed it so that between the end of a wire and the block of cylinders of the engine there was a gap about 6 mm. The wire can be held the tool with the isolated handles.
9. Turn the engine a starter and check existence of a blue spark between a wire and the block of cylinders of the engine.
10. If the spark is present, check a condition and operability of fuel system.
11. If the spark still did not appear, disconnect the central high-voltage wire from a cover of the distributor of ignition, and fix it so that between the end of a wire and the block of cylinders of the engine there was a gap about 6 mm. The wire can be held the tool with the isolated handles.
12. Turn the engine a starter and check existence of a blue spark between a wire and the block of cylinders of the engine.
13. Existence of a spark specifies that the coil of ignition is serviceable, and faulty, probably, the cover of the distributor of ignition, a distributor rotor are, or the reason is wear of coal contact or a spring of coal contact in a cover of the distributor of ignition.
14. If the spark still did not appear, check reliability of connection of wires to the ignition coil. Probably also oxidation of wires of the distributor of ignition.
15. Clear contacts and repeatedly make check of system of ignition.
16. Using additional wires, connect the voltmeter or a control lamp between a wire of giving of tension to the ignition coil (disconnected from the coil) and weight.
17. Lack of tension indicates damage of an electric chain of giving of tension to the ignition coil from the ignition lock.
18. Disconnect the condenser and check tension existence between mobile contact of the breaker and weight.
19. If tension is present, means, the condenser failed.
20. If tension is absent, check tension existence between weight and the plug of the coil of ignition with a wire going to the distributor.
21. Existence of tension indicates break of the wire connecting the coil of ignition and the distributor of ignition.
22. Lack of tension indicates malfunction of the coil of ignition.

IGNITION ADMISSIONS

Unsystematic admissions of ignition can be caused by the weakened contacts, a rupture of a chain in a control system of ignition or in a chain of primary winding of the coil of ignition, damage of high-voltage wires.

PERFORMANCE ORDER
1. Switch off ignition and check that contacts on electric sockets of system of ignition pure and without corrosion traces.
2. Check that the ignition coil, a cover of the distributor of ignition both high-voltage wires pure and dry.
3. Check a condition of electric wires of spark plugs.
4. Then check a cover of the distributor of ignition, coal contact and a rotor of the distributor of ignition.
5. Check of spark plugs can be made serial replacement of spark plugs by the new.
6. Constant admissions of ignition are caused, most likely, by defects in a cover of the distributor of ignition, the ignition coil, high-voltage wires or spark plugs. For check of giving of a high voltage to spark plugs it is possible to use a stroboscope.
7. Lack of tension only on one high-voltage wire testifies to damage of this wire or a cover of the distributor of ignition.
8. If tension is present on all high-voltage wires, means, spark plugs are faulty.
9. At total absence of a high voltage check a secondary winding of the coil of ignition which can be damaged.
10. If at system of ignition there are malfunctions which it is impossible to eliminate independently, it is necessary to address on service station.

PRECAUTIONS

At works on electric system not to damage semi-conductor devices (diodes and transistors), is necessary to fulfill the following requirements:

  – in operating time of the engine do not disconnect the accumulator, the generator of an alternating current or any electric sockets;
  – at carrying out any works remove the negative plug from the accumulator;
  – at carrying out electrowelding works on the car disconnect the generator of an alternating current and the electronic control device;
  – do not allow operation of the engine with the generator disconnected from electric system;
  – do not check operability of the generator, closing its target contacts on weight.
