3.3.3. Check of candles накаливания

THE GENERAL DATA

Candles накаливания check on the cold engine at completely charged storage battery pressure not less than 11,5 V.Dlja checks of the current strength, consumed by candles накаливания, the direct current ampermeter is necessary. Its one conclusion connect on the isolated wire, another – to "weight", and the current strength is measured at the expense of an induction.

PERFORMANCE ORDER

1. To include the ampermeter in a candle chain накаливания. 2. To disconnect a wire from the gauge of temperature of a cooling liquid. 3. The ignition key to include candles накаливания a maximum on 15 with. 4. To measure a current consumed by candles накаливания. It should make nearby 60 And. 5. A current passing through one candle, about 12 A.Sledovatelno if the measured value is equal 48 And one candle is damaged, 36 And – two candles, 24 And – 3 candles, 12 And – 4 candles. If the ampermeter shows a zero, i.e. absence of consumption of a current, it speaks about malfunction of all candles. 6. To define a faulty candle, to disconnect a wire and the current carrying tyre from candles накаливания. To connect a sampler wire to «плюсовой» to the plug of the storage battery and serially to put a sampler to each candle, as is shown in drawing. If the sampler lamp lights up, the candle means is serviceable, if is not present – is damaged also it it is necessary to replace. A new candle to twirl and tighten the moment 30 Н·м (3,0 кгс·м). The specified moment of an inhaling not to exceed in order to avoid candle damage. To connect the current carrying tyre and a wire. 7. If as a result of checks of candles malfunction is not found out, and the engine is badly started, to make visual check of candles during their heating. For this purpose to remove atomizers and to observe of work of candles through apertures for atomizers. If candles with the burnt out tips as in drawing, it means faults in work of atomizers come to light. Replacements of such candles insufficiently, it is necessary to check up, besides, atomizers on pressure of injection and tightness. Thus also it is necessary to be convinced that the fuel stream dense and is well sprayed. Work of atomizers is recommended to be checked at servicing deport.
