Check of system of preheat

If there are difficulties at engine start, at first it is necessary to check a compression. In case of an insufficient compression the engine is not started at low temperatures. Compression check see. Head Petrol engines, Section compression Check.

Check of candles of an incandescence


    To unscrew cables of candles of an incandescence.
    To connect an ohmmeter serially to each candle and to check, whether the current between the block of cylinders and candle contact proceeds.
    If the current does not proceed, the glow plug is faulty and should be replaced.
    To unscrew a faulty candle. To insert a new candle and to tighten with effort of 20 Nanometers.

The moment of an inhaling should not be exceeded, the thermal core and a candle differently will be damaged will prematurely fail. To watch that on a candle oil or fuel did not get. To observe instructions for the scorched cores.

    To establish cables and to tighten with effort of 20 Nanometers.

If malfunction is not found, though the engine is started badly, visually to check glow plugs at heat. For this purpose to remove nozzles and to observe candles at heat through openings.

Candles with the scorched cores

The scorched cores often are a consequence of malfunctions of nozzles. Similar damages cannot be caused by shortcomings in or on glow plugs. If glow plugs with similar damages - an arrow are found - it is not enough to replace of them only. Also it is necessary to make check of pressure of dispersion and tightness of nozzles (it is carried out in a workshop).

Check of the relay of candles of an incandescence


    To disconnect tips from the relay of candles of an incandescence.
    To connect the relay to the battery by means of two auxiliary wires. To connect an ohmmeter and to measure by resistance between two plugs.

Resistance should be equal 13 Ohm.

    If value does not correspond demanded, the relay should be replaced.
