You will need
- - control lamp;
- - the voltmeter;
- - connecting wires.
Install the vehicle on the hand brake, turn the transmission into neutral. It is desirable to diagnose the ignition system, simulating the operation of the engine, rather than scrolling the starter to the crankshaft. This allows you to conserve battery power. The imitation of the operation of the ignition system occurs when the opening of the green (signal) wire to the Hall sensor ground. The pigtail should be short the wire to ground and break, eventually the switch will see the pulse and then to apply it further to the ignition coil. But there are special devices that simulate the operation of the Hall sensor. They are collected according to the scheme of the multivibrator. The device in one second makes a few pulses.
Check whether all properly in the car. Just need to find out whether the cause of failure is in the ignition, not the fuel supply system. Also check the timing belt. When it is open, the starter will spin the crankshaft faster than usual. Distributor, of course, will not rotate since it is driven by the camshaft.
Check voltage at the ignition coil. To make it easier lamp of 12 Volts and power up to 3 Watts. Of course, a multimeter measurement will be more accurate. Turn on the ignition and connect to terminal "B" of the coil lamp. She needs to burn. If it is not flammable, it is indicative of the absence of voltage. The cause of the fault may lie in the wiring or in the ignition switch or relay.
Continue to check the ignition coil and the distributor in the presence of voltage. On the HV coil connector connect the discharger (or bronirovat with tip and spark plug). Imitate the pulse from the Hall sensor by grounding the green wire to ground. Needs to slip a spark. If the spark is there, it speaks about the serviceability of the coil, but the Hall sensor is defective, it must be replaced.
Check the switch, making the measurement of voltage on the output coil that is connected to the brown wire. Of course, the ignition must be turned on. If no voltage, then there is a malfunction of the switch. If there is voltage, it is required to check whether the switch pulses. Disconnect the brown wire from the coil. Lamp connect the wire to terminal "B" of the coil. To carry out these switch need ignition switch off. After the circuit assemblies switch on the ignition and spin the starter. The light should be blinking.
Advice 2 : How to check babineaux VAZ
Ignition coil (Babina) is an automotive alternator, which is one of the main components of the ignition system of the automobile engine. Babina transforms a sharp decline in voltage from the switch in the high voltage pulse.
You will need
- - key end "10";
- - the ohmmeter.
First, inspect the plastic cover of the ignition coil for mechanical damage, cracks, dirt, leakage and overheating of the oil. If you found something, you need to replace the coil.
Check the ignition coil (Babin) without removing it from the car, but still, on the advice of experienced motorists, masters, best to remove it for easy access with your car. For removing, take the Allen key to "10".
As any Babina consists of primary, secondary winding and electrical connections, you must first check the resistance of the primary winding of the ignition coil, which receives intermittent low-voltage current. To do this, connect the ohmmeter to the low voltage terminals of your Babin. Remember that the resistance at 25 ° C shall be (0,42±0,05) Ohms at the ignition coil 8352.12 and (0,43±0,04) Ohms at the ignition coil 3122.3705. If it differs from the standard value, it is necessary to replace it.
Then you need to check the resistance of the secondary winding of the ignition coil (Babin), which is induced by a high-voltage current. To do this, connect the ohmmeter to the low-voltage terminal b and Babin to the high-voltage terminal. But don't forget that the resistance at 25 ° C should be (5,00±1,00) whom have the ignition coil 8352.12 and (4,08±0,40) com at the ignition coil 3122.3705. If it differs from the standard value, it is necessary to replace it. Most importantly - do not forget to remove the electrical connectors from the ignition coils.
And finally, you should check the insulation resistance to ground. And for this you need to connect an ohmmeter to the body Babin and alternately to each of its terminals. If the resistance of the ignition coil less than 50 MW, it means it is faulty and you need to put a new.
Advice 3 : How to check contactless ignition for VAZ 2107
Contactless ignition system does not require special care. However, to keep clean the connecting wires is still needed. The contamination and pollution of the contacts can cause current leakage. In the end the engine will run rough or not start.
You will need
- - control lamp;
- - multimeter;
- device check BSZ;
- - wire.
Check plug connections on the switch and the distributor, if suddenly the car started to jerk, the engine is misfiring and the tachometer needle began moving erratically. Very often there is pollution and contamination of the contacts, causing the switch accepts all signals from the Hall sensor. Solvent washing, penetrating lubricant will help to get rid of this trouble. You can even wipe the contacts with a damp cloth.
Swipe a thorough inspection, if the car did not start. To check is best to use the emergency plug. This small blocks that mimic the operation of the Hall sensor and switch. Check the Hall sensor – is the first step. If there is no simulator, it is necessary for the high-voltage output coil to connect bronirovat with a tip and a candle.
Short the green wire to ground with the ignition on. At the time of opening needs to slip the spark plug. If the opening appears a spark, but when cranking the starter it does not, then the faulty Hall sensor or broken wire it. You can also take a test light and connect it between the 6 and 3 pin switch. At slow rotation of a crankshaft lamp gradually light up and gradually dim.
Check the switch device for diagnostics. If there is none, use the test lamp. The bulb must be power up to 3 Watts, working voltage is 12 Volts. One output of a lamp connected to ground, and the other is connected to the first output of the switch. This is the conclusion, which is the brown wire on the ignition coil. If the voltage to the coil is supplied, and with the closure of the green sensor wire to ground at the output of the coil have spark, the problem lies in the distributor.
Remove the ignition distributor cap. Carefully inspect it for damage. A crack in the housing covers may cause a large leakage current, why would lack power spark, it will not reach the electrodes of spark plugs. Inspect the contacts if they are dirty, clean them. The runner is a resistor that also can fail, it will not spark to the plugs. Check the resistor you need an ohmmeter. The resistor should be about 5 ohms. If it is significantly different from this number, something will have to change the slider rail.
Do not transgress on the nodes of the ignition system. Often the fault lies in the wiring. Before diagnosing check all connections for breaks.
