Scheme for switching on sound signals
1 - sound signals; 2 - relay for turning on sound signals; 3 – the switch of sound signals; 4 - fuse block; 5 - generator; 6 - battery.
Sound signals are activated by the central button of the steering wheel. The contact ring of the switch is fixed on the steering wheel, and the spring-loaded contact is on the housing of the steering column switches.
Previously, two sound signals of low and high tone S-309 and S-308 were installed, which were switched on through a relay. Since 1993, one sound signal 20.3721-01 has been used. It has a signal adjustment screw and a built-in relay.
The signal is not separable - in case of failure it must be replaced.
