1. Check of a condition of VV of wires has to be made every time when replacing spark plugs (see the previous Section Check of a State and Replacement of Spark Plugs).
2. Check begins with external survey of isolation of wires at the working engine. Drive the car into the dark, well ventilated room, start the engine and make sure of lack of sparking on wires. Sparking is an isolation breakdown sign. Try not to touch moving components in a motive compartment. Make necessary marks on replacement of defective wires, then let's the engine cool down and start checks of a condition of a cover and the runner of the distributor of ignition.
3. Check of candle wires is made serially in order to avoid violation of an order of their connection at assembly. Usually on isolation of company wires there is the corresponding marking. In case of absence that, put it independently by means of an adhesive tape and a marker.
4. Disconnect VV a wire from a spark plug (best of all use the special tool). Do not pull for a wire, only for its tip at all.

On models of the last years of release for the purpose of ensuring access to spark plugs it is necessary to remove the top cover from a cover of a head of cylinders. |
5. Examine internal walls of a tip. Corrosion is usually shown in the form of a fragile korkoobrazny raid of white color. In case of strong oxidation replace a wire.
6. Pull a tip back on a shaft of the candle, make sure of density of its landing. In case of need again remove a tip and as appropriate turn in plugs in a rubber cover.
7. Wipe with pure rags a wire on all its length, having completely removed traces of dirt and lubricant from the surface of isolation. Examine isolation of a wire on existence of cracks, traces of a progar and other damages. Try not to bend a wire under acute angles in order to avoid violation of integrity of veins of the conductor in isolation. |
