| 1. For check of integrity of a chain connect the device for verification of schemes or negative щуп the voltmeter to the negative plug of the accumulator or the earthed element. |
| 2. Connect the second щуп to connection in a checked chain, it is desirable for the next to the accumulator or a safety lock. Thus this site of a chain should be energized from the accumulator if only the connection socket to the accumulator does not carry out a current or did not fuse a safety lock (thus do not forget that some chains of electric equipment join only at key turn in the ignition lock in a certain situation). |
| 3. Include the chain, then connect щуп a tester to the connection closest to the switch of a chain on the party of the checked element. |
| 4. If tension is present (about what the control bulb testifies or voltmeter indications), it means that the chain site between the corresponding connection and the switch has no gaps. |
