Security measures at work with ignition system

In electronic system of ignition pressure reaches 40 sq. Under adverse conditions, for example, humidity in an impellent compartment, pressure throws can punch isolation that in turn can lead to electric blow.

For an exception травмирования people and-or damages of electronic system of ignition it is necessary to observe following security measures:

      •  to Wash the engine it is necessary only after its deenergizing.

      •  By manufacture of welding works it is necessary to disconnect all cables of the storage battery.

      •  it is not necessary to switch off the generator and a starter at the working engine.

At compression check necessarily disconnect the main relay (1) DME to exclude work of the coil of ignition. (2 - safety locks DME). Address to an accompanying illustration. Check up a compression, address to Section compression Check.

      •  Wires of system of ignition are necessary for disconnecting only at the switched off ignition.

      •  Connection and switching-off of wires of measuring devices (an ignition tachometre/tester) is necessary for making only at the switched off ignition.

      • the  Primary party (the high voltage party, the party of spark plugs) ignition systems should be loaded by resistance at least 4 clod. Tips of spark plugs should be attached.

      •  In no event it is impossible to start the engine at disconnected from the coil of ignition a cable (the plug 4).

      •  it is not necessary to attach to the plug 1 (-) ignition coils помехоподавляющий the condenser and a control lamp.

      •  it is not necessary to connect the plug of 1 coil of ignition to weight or the storage battery. At the subsequent installation of the anticreeping alarm system it is impossible to use a wire to the plug 1 for start-up blocking.

      •  It is impossible to start the engine right after heating to temperature more + 80С (for example, at painting, processing by steam).

      •  it is not necessary to spend works with electronic system of ignition to the persons having a warm stimulator.
