Determination of a faulty consumer (Mondeo 2)

If a working battery suddenly does not supply current, this may mean that some consumer in the on-board network has completely discharged the battery.

Search for a faulty consumer as follows:

- disconnect the negative wire from the battery, connect the wire of a universal measuring device - a multimeter between the negative terminal and the battery wire. If the device shows current, then there is a faulty consumer;

- connect the ground wire, open the fuse box and remove one fuse;

- connect a multimeter to the contacts, if there is no current, then the corresponding electrical circuit is in order. A weak current is also not yet a cause for concern, since devices such as a clock, radio or alarm systems constantly consume energy from the battery, the current strength is significantly less compared to the needs of the faulty consumer;

- repeat the measurement process until the device shows a high current. Determine from the fuse table which consumers are connected to this electrical circuit;

- remove consumers sequentially and measure the current. If the multimeter does not show the current, the faulty consumer has been detected.
