Pay attention to the following:

- Check up reliability of a contact socket of the coil with the management block;

- Check up the case of the coil of ignition on presence рисок and traces подгорания, caused by spark breakdowns;

- Check up contact of wires of a high voltage to candles, they should not be oxidised;

- Check up high voltage wires, on their isolation there should not be attritions. The wires having shabby or burnt slightly places, should be immediately replaced. On a defective wire the spark can go by the way of the least resistance, and you will hear clicks and cracklings under a cowl;

- Remove a touch of calcium and salt from high voltage wires.
