How to check contactless ignition

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.
