  1. Carrying out numerous unsuccessful attempts of start of the engine, or leaving of lighting fixtures included for a long time at the idle engine;
  2. Violation of serviceability of functioning of system of charging (the driving belt of the generator weakened or is torn off, the electrical wiring is damaged, or the generator is faulty);
  3. Malfunction of actually rechargeable battery (electrolyte level fell, or there was accumulator service life).

When performing start of the engine from the external power supply it is necessary to pay attention to observance of some special precautionary measures:

  1. It is not necessary to try to start the engine from the frozen rechargeable battery, - previously warm up it;
  2. Start of the engine from the auxiliary power supply has to be made only at the cold power unit and the catalytic converter;
  3. It is not necessary to carry out start by means of the device for the accelerated charging of the rechargeable battery;
