4.2.5. Check of candles of an incandescence


Check conditions

Tension of an onboard network of the car should be not lower than 11,5 Century.

The control unit the engine should be in a normal state.

Safety locks in a chain of giving of tension to glow plugs should be serviceable.


Use of a light-emitting diode sampler for check of operability of candles of an incandescence

If the light-emitting diode lights up, means, the glow plug is faulty. If the light-emitting diode does not light up, the candle means is faulty, and it is necessary to replace it.

1. Switch off ignition.
2. Disconnect from incandescence candles electric sockets.
3. Connect a control light-emitting diode to the positive plug of the accumulator and in turn connect the second plug of a light-emitting diode to glow plugs.
4. In the presence of the ampermeter measuring big currents, connect it between the positive plug of the accumulator and glow plug contact. Measure a current consumed by a glow plug. If the current consumed by a candle, exceeds 15 And, the glow plug means is faulty.
5. Unscrew glow plugs.
6. Check each glow plug on existence of mechanical damages. The burned or destroyed tips of a glow plug can be from a bad stream of dispersion of fuel a nozzle. If there is such damage, it is necessary to check and, if necessary, to replace fuel nozzles.
7. Operability of candles of an incandescence can be checked, submitting on them 12 V.Pri etom they should heat up evenly and for a demanded interval of time. Thus it is necessary to observe precautions:
      – to hold a glow plug a special clip or flat-nose pliers;
      – the electric power-supply circuit of a glow plug should have the fuse;
      – after check the glow plug should be cooled within several minutes.
8. The glow plug in a good condition heats up to reddening of a working tip within 5 seconds. At longer heating or heating in an average part, instead of on the candle end, the candle is faulty and is subject to replacement.
