Ford Fokus>> Electric equipment>> The storage battery>> Faulty consumers reduce capacity of the storage battery
If you have noticed that completely the serviceable battery began to be discharged at the idle engine and the switched off consumers, means in an onboard network there is a current leak, the faulty consumer can be the reason for that.
For search of the faulty consumer execute operations in the following sequence:
- Remove a wire of "weight" from the negative plug of the storage battery. A multimeter connect between the negative plug of the battery and the wire removed from the battery. If the device shows current presence, means in a network there is a faulty consumer;
- Connect a wire of "weight" to the negative plug of the storage battery. Open a cover of the assembly block of safety locks and take out one of safety locks. On free contacts attach a multimeter. If the current in a chain is not present, the checked chain is perfectly in order. The small current is not at the bottom for anxiety. Devices, such as the onboard computer, hours, radio and the alarm system, constantly are alive. The size of the electric power consumed by them is much less, than in the presence of the defective consumer of the electric power;
- Repeat similar measurements on the assembly block while your multimeter will not show the raised value of a current in the given chain. Under the scheme of the electric connections which is available in the given instruction, you can define, what consumers are included in the given chain;
- Consistently disconnect the consumers which are in the checked chain, each time measuring a current. When the multimeter will not show current passage, it is possible to consider that you have found out a defective unit.
