Check of a small horn of a sound signal
The constant control If ignition is included, by pressing a small horn plate in a steering wheel, the double sound signal should sound. Small horn contact creates connection with weight in an electric chain of management of the relay of a small horn of a sound signal (the head the Electrotechnical equipment). Current giving to the relay is carried out from the plug 75 locks of ignition which submits power supplies only at the included ignition. In the closed electric chain (i.e. at the pressed plate of a small horn of a sound signal) relay contacts become isolated, and on small horns of a sound signal the current on a wire in a black/yellow cover moves. Connection with weight is carried out on a brown wire. The small horn of a sound signal is faulty?
