An inspection of tension needs to be carried out if the electric chain is faulty.
Connect one of probes of a control bulb to the negative plug of the accumulator or (mass) of the car. Connect the second probe to connection in the checked chain, it is desirable located as it is possible closer to the accumulator or a safety lock.
If the control bulb lights up, tension is present. It means that a part of a chain between connection and the accumulator is serviceable.
Continue check of other part of a chain in the same way.
When you find a point where tension is absent, it means that the source of malfunction lies between this point and the last point where tension was present. The majority of problems is caused by bad connection.
Prevention
Do not forget that tension is only present at some chains if to turn a key in the ignition lock in a certain situation.
