Electric checks

At suspicion on malfunction of system of ignition first of all make sure that all its components are pure and dry, and plugs are not oxidized and reliably fixed. Check a condition (charge level) batteries and correctness of installation of a corner of an advancing of ignition.

If elimination of the revealed defects the engine on the former is not started, execute the special checks listed below.

PERFORMANCE ORDER

Disconnect VV a wire from a suspected spark plug and connect it to obviously serviceable candle. Expose an interelectrode gap of a candle of equal about 6 mm, reliably earth the candle case on weight and ask the assistant to turn the engine. If the spark is not formed, pass to the checks described below. Remove all VV of a wire and by means of an ohmmeter check them on existence defined (with the set resistive resistance) conductivity. Check a condition of VV plugs of wires. Disunite the electric socket of the coil. Include ignition and check on existence of tension of the battery the plug of 1 socket of a plait (see an accompanying illustration). Tension should take place. 1 — the socket on a plait 2 — the socket on the coil At the switched-off ignition disunite the electric socket of the distributor. Check on conductivity existence electroconducting a boundary the socket of a plait of the coil and the socket of a plait of the distributor (see an accompanying illustration). 1 — the socket of a plait of the coil 2 — the socket of a plait of the distributor Disconnect VV a wire from the ignition coil. Give fixing bolts and remove the coil from the car. By means of an ohmmeter measure resistance between plugs of the coil of ignition. Demanded value makes 0.8 ÷ 1.0 Ohm. Measure resistance between the plug of 1 socket of the coil and the VV plug of a wire of the coil. Demanded value makes 7.6 ÷ 11.4 kiloohms. In case of need replace the coil. Uncover the distributor. Having turned the engine, achieve combination of the blade of an alarm rotor with a ledge on the inductive sensor. By means of pure щупа lezviyny type measure size of an air gap between the blade of a rotor and a sensor ledge. In case of need weaken fixing screws and as appropriate correct position of the sensor. If during performance described above checks it is not revealed any violations, and the engine is not started, remove spark plugs and check their general condition and size of an interelectrode gap.
