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