| 1. For detection of a source of short circuit in the beginning disconnect elements of loading of a chain (elements of loading of a chain are elements which consume an electric current, such as bulbs, electric motors, heating elements etc.). |
| 2. Remove the corresponding safety lock and connect щупы a tester or the voltmeter to safety lock plugs. |
| 3. Include a food in chains, thus do not forget that some chains of electric equipment join only at key turn in the ignition lock in a certain situation. |
| 4. If tension is present (about what the control bulb testifies or voltmeter indications), it means that in a chain there is a short circuit. |
| 5. If at carrying out check of tension is not present, however the safety lock on the former fuses at connection of the same loading of a chain, it testifies to failure of an element of loading. |
