| 1. For check of integrity of a chain connect the device for check of schemes or negative probe the voltmeter to the negative plug of the accumulator or the earthed element. |
| 2. Connect the second probe to connection in a checked chain, it is desirable for the nearest to the accumulator or a safety lock. Thus this site of a chain should be energised from the accumulator if only the connection socket to the accumulator does not spend a current or has not fused a safety lock (thus do not forget that some chains of an electric equipment join only at key turn in the ignition lock in certain position). |
| 3. Include a chain, then connect probe a tester to the connection nearest to the switch of a chain on the party of the checked element. |
| 4. If pressure is present (about what the control bulb testifies or voltmeter indications), it means that the chain site between corresponding connection and the switch has no ruptures. |
| 5. Continue chain check by the same image before site detection on which there is no pressure that means that chain rupture has occurred between this point and a point of the previous check on which there was a pressure. |
