The movement with the defective generator

If the generator or the regulator of tension do not work, it is possible to continue a trip since the accumulator can help to start the engine.
During daylight hours current in the accumulator will be enough for limited time in spite of the fact that the electronic system of ignition/injection needs the minimum current, as well as the electric fuel pump. Besides the accumulator is often charged only on 2/3.

And still depending on the capacity of the accumulator of current will be enough approximately for a five-hour trip. It is more difficult in the winter since the accumulator badly reacts to cold. Besides, light is necessary to you much earlier. The economy of current is important:

  • Do not interrupt without cause the movement. The starter consumes especially a lot of energy. If it is possible, push the car.
  • It is impossible to include heating of back glass, the supercharger of air and the radio receiver.
  • Manage, whenever possible, economically with a screen wiper.
  • Move without driving beam and fog lights at night.
  • Unscrew wires from the generator and isolate them separately in order that the accumulator could not be discharged because of the defective generator or the regulator of tension.
