Technical characteristics



Engine of screen wipers

The engine of screen wipers at the included ignition is supplied with current via the relay of unloading of H-contact and a safety lock (the head the Electrotechnical equipment). Thus plugs of wires on the engine of screen wipers have the following value:

  • On the plug 53 tension for work of screen wipers at the first speed arrives.
  • The plug 53a gives positive current for installation of screen wipers to final situation.
    I.e. the engine of screen wipers receives positive current via this plug until the engine does not come to the provision of a parking.
  • The plug 53b gives tension for work of screen wipers at the second speed.
  • Via the plug 53e the engine of screen wipers is stopped at their return movement after switching off in order that screen wipers did not go beyond the provision of a parking.
  • The plug 31 provides contact with weight.

 Council: At the included ignition of a brush of screen wipers should not be blocked out of the starting position – for example, snow or due to freezing. In this case from the plug 53a tension continuously arrives. Since the engine of screen wipers because of the blocked brushes cannot rotate, through certain time it will burn down.
