Light signal

Not important, are included or not ignition or headlights, a thread of an incandescence of headlights of a driving beam and a control bulb of a driving beam always flash, if you pull to yourselves the lever of indexes of turns on a wheel. If the light signal does not work, though headlights burn at the included ignition:


  1. Dismantle elements of the switch of the lever (head Tools and devices).
  2. Check a control lamp, whether there is a tension on both plugs of 30 red wires to an element of the switch of the lever.
  3. If yes, that the lever of a light signal is faulty. Replace a switch element assembled.
