Security measures at work with ignition system

In a motor compartment of the Audi 80 car the special plate warns about a high voltage in ignition system, and it is not so causeless: in a thin wire of a chain of management there can already be tension to 100 In with a big current, not to mention the dangerous high-voltage tension of ignition making over 30 000 In (but with a small current). Though, fortunately, it is not known about the car owners killed by system of ignition, but nevertheless the touch to not isolated wires in adverse conditions can become very dangerous, especially for the people having warm diseases. Therefore:

  • To touch all electric cables – and to connections of control devices, – and also to disconnect or connect them follows only at the switched-off ignition.
  • To disconnect the storage battery follows only at the switched-off ignition.
  • If the engine needs to be turned simply a starter, without starting, it is necessary to disconnect ignition system (see the following section).

  • Before washing the engine, it is necessary to disconnect ignition system.
  • For engine start at the discharged storage battery by means of the device for the accelerated charge it can be connected not more long than for one minute, and tension should not exceed 16,5 Century.
  • At obvious or expected defect of system of ignition it is necessary to disconnect ignition system at car towage (see the following section).
  • It is impossible to connect the condenser to the plug 1/-of the coil of ignition.
  • Begunok of the distributor of ignition is impossible заменть for the first comers, his resistance makes 1 kiloohm and «R1» designation (models with 4-and 5-cylinder engines).
  • To apply with high-voltage thick wires of system of ignition only resistance of 1 kiloohm.
  • To apply only such contact tips of the spark plug which resistance makes 5 kiloohms.
  • At carrying out electrowelding works in the car cables of the storage battery should be disconnected.
