1. The most reliable results are given by check with use of the scheme of inclusion of the relay. If the inclusion scheme is absent, execute checks taking into account following data. |
2. The pair of conclusions of any relay is connected to the coil providing operation of the relay. Other conclusions become in pairs isolated or disconnected at запитывании coils. |
3. As a rule, distributing of contacts is specified on the relay case. |
4. Connect one of conclusions of the coil of the relay to a positive conclusion of the battery through a wire with a thin delay as a safety lock. The second conclusion connect to weight. After connection click should be listened. If click is not present, change polarity of connection (polarity of connection matters on some relays). |
5. Check up chain presence between relay conclusions according to marks on the case. |
6. If results of checks negative the relay replace. |
