3.3.3. Check of candles of an incandescence


Glow plugs check on the cold engine at completely charged battery not less than 11,5 V. For check of current, consumed by glow plugs, the ampermeter of a direct current is necessary. One its conclusion is connected on the isolated wire, another – to "weight", and current is measured due to induction.

1. To turn on the ampermeter in a glow plug chain.
2. To disconnect a wire from the sensor of temperature of cooling liquid.
3. The ignition key to include glow plugs at most on 15 villages.
4. To measure the current consumed by glow plugs. It has to make about 60 And.
5. The current passing through one candle, about 12 A. Sledovatelno if the measured value is equal 48 A, one candle, 36 A – two candles, 24 A – 3 candles, 12 A – 4 candles is damaged. If the ampermeter shows zero, i.e. lack of consumption of current, it speaks about malfunction of all candles.
6. To define a faulty candle, to disconnect a wire and the current carrying tire from incandescence candles. To connect a sampler wire to the "plus" plug of the battery and serially to put a sampler to each candle, as shown in drawing. If the lamp of a sampler lights up, the candle means is serviceable if is not present – is damaged and it needs to be replaced. A new candle to twirl and tighten the moment of 30 N · m (3,0 kgfs · м). Not to exceed the specified moment of an inhaling in order to avoid damage of a candle. To connect the current carrying tire and a wire.
7. If as a result of checks of candles malfunction is not found, and the engine is badly started, to make visual check of candles during their heating. For this purpose to remove nozzles and to watch work of candles through openings for nozzles. If candles with the burned-out tips as in drawing, it means interruptions in work of nozzles come to light. It is not enough replacement of such candles, it is necessary to check nozzles for pressure of injection and tightness, besides. Thus it is also necessary to be convinced that the fuel stream dense and is well sprayed. Work of nozzles is recommended to be checked for service stations.
