Check of a state and replacement of the breaker of indexes of turn / alarm system

All considered models are equipped with a safety cushion. The pillow constantly is in the "alerted" state and can work (to be inflated) at any moment at the connected battery. In order to avoid casual operation of a pillow (and receiving as a result of a trauma) every time when carrying out any works with components of a security system disconnect a negative wire from the battery. After a wire detachment from the battery before getting to work wait at least two more minutes (the system is equipped with the condenser which needs time for a discharge). In more detail about work of a security system see the Section Safety cushion - the general information.

The breaker of indexes of turn / the alarm system represents a kanistroobrazny form of the relay, the providing blinking of lamps of indexes of turn / the alarm system at turning on of the corresponding switch. On models of 1993 of the issue two separate blocks are installed on a back wall of the service center under the dashboard from its driver's party. Models of 1994 of the issue are equipped with one combined breaker placed in a relay box in a ware box (The section of the Relay - the general information).

Breakers of indexes of turn and alarm system.

Regularly functioning breaker publishes clicks well distinguishable aurally during the work. The refusal of functioning of one of indexes of turn which is followed by increase in frequency of clicks of the breaker speaks about failure of the corresponding lamp.

The simultaneous refusal of both indexes of turn can be caused by failure of a safety lock, defect of the breaker, malfunction of the switch or violation of quality of contact or break of conducting in a contour. If external survey revealed combustion of a safety lock of a contour before making its replacement check an electrical wiring for existence of short circuit.

For replacement of the breaker just take it from the socket and insert new on its place.

Track that the new breaker was identical on type old.
