15.4.2. Detection of a rupture of a chain
For check of integrity of a chain, connect the device for verification of schemes or the negative probe of the voltmeter to the negative plug of the accumulator or the grounded element. Connect the second probe to connection in the checked chain, it is desirable for the next to the accumulator or a safety lock. Thus this site of a chain has to be energized from the accumulator if only the socket of connection to the accumulator does not carry out current or the safety lock did not fuse (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). Include a chain, then connect the tester probe to connection, the next to the chain switch on the party of the checked element. If tension is present (to what the control bulb or indications of the voltmeter testifies), it means that the chain site between the corresponding connection and the switch has no gaps. Continue check of a chain in the same way, and after detection of a site on which there is no tension, it means that the rupture of a chain occurred between this point and a point of the previous check on which there was tension. The majority of problems of the opened chain are caused by the broken or weakened socket. |
