13.24.3.2. Detection of a source of short circuit

Elements of loading of a chain are elements which consume electric current, such as bulbs, electric motors, heating elements, etc.

PERFORMANCE ORDER
1. For detection of a source of short circuit disconnect chain loading elements.
2. Remove the corresponding safety lock and connect probes of a tester or the voltmeter to safety lock plugs.
3. Include food in chains, at the same time do not forget that some chains of electric equipment join only at turn of a key in the ignition lock in a certain situation.
4. If tension is present (what the control bulb or indications of the voltmeter testifies to), it means that in a chain there is a short circuit.
5. If when conducting check there is no tension, however the safety lock still fuses at connection of loading of a chain, it demonstrates failure of an element of loading.
