2.17. Check of high-voltage wires, бегунка and distributor covers

Characteristic defects of a cover of the distributor
1. Breakage on turrets of wires

2. Cracks

3, 5. Breakdown

4. Erosion of electrodes

6. Deterioration of a piece of coal

Characteristic defects бегунка
1. Loss of elasticity of a spring

2. Contact corrosion

3. Задевание for a cover

4. Cracks

High-voltage wires of spark plugs should be checked (and if necessary to change) simultaneously with replacement of candles.

The elementary way of check consists in survey of wires on the working engine in the blacked out garage. At detection of a luminescence (breakdown) of a wire replace. Check up a condition of a cover and бегунка the distributor.
1. Disconnect the battery from weight.
2. For check and clearing of wires disconnect each wire separately.
3. Disconnect a wire from a candle, keeping for a tip.
4. Check up corrosion presence on a socket of a tip of a wire and on a candle electrode. Check up durability of demountable connection, having dressed on a candle a tip of a wire and having shaken it. At leaky connection draw in contact petals.
5. Wipe wires. A wire strongly do not bend, as the current-carrying vein can break. At detection of cracks, traces of breakdown and подгорания wires replace.
6. Disconnect a wire on a cover of the distributor and check up a condition of contacts of wires and sealants.
7. Turn away fastening screws (or wring out скобы) and uncover the ignition distributor.
8. Wipe a cover absolutely and check up presence inside and outside of a cover of cracks, traces of superficial breakdown (the thin charred paths), deterioration, подгорания and easings of contacts. At detection of such defects a cover and бегунок replace.
