Relay
Relays are in many current circuits. The relay of inclusion work as a switch. For example: if a headlight switch is turned on manually, the corresponding relay receives the signal of the power supply to the headlight high beam. Many tokoemkih consumers (headlights, wipers, fog lamps) are in the chain of the relay to not much load switch or have a shorter current path. There are also functional relay, for example, of cleaning and washing windows or interior lighting time switch. Check
Connecting the relay contacts are normalized. When the relay is controlled by the consumer. This means that the supply inrush current to terminal 68, the circuit switching to terminal 85 is closed. The magnetic coil inside the relay core pulls and closes the current loop "operating current". "Working current" comes from the terminal 30 through the relay terminal 87 and then to the consumer.
The easiest way to test the functionality of the relay is possible, replacing it with a new serviceable. This is done, and the service station. Since the fan is not always at hand the relay, it is recommended the following working methods in dealing with the relays, which, among other things, are used for headlights and fog lamps. These designations may be different terminals and, above all, from the standard set by the relay.
| PERFORMANCE ORDER | | 1. Pull the switch out of the slot. | | 2. Turn on the ignition and relevant switch. | | 3. Check the first indicator of voltage presence of voltage at terminal 30 (+) in the relay socket. For this indicator connected to earth (-), the second wire carefully applied to terminal 30 in the relay socket. If the LED indicator lights up, the voltage is. If the meter reads the voltage, to determine the open circuit from the positive pole of the battery (+) to the terminal 30 for the circuit diagram. | | 4. Produce a jumper from the insulated wires, exposing the ends. | | 5. Connect this jumper in the socket terminal 30 (+) battery, always under tension) to the output terminal of the relay switch 87. This technique is the same thing that would make the serviceability of the relay, whether it is installed. | | 6. If the jumper is installed, for example, the high beam lights, the relay is faulty. | | 7. If a headlight does not come on, to find out whether the connection weight from the headlamp. Then, with the help of wiring diagrams, find the break in the wire from the terminal 87 to the headlamp and remove. | | 8. If necessary, replace the relay. |
