13. The electrotechnical equipmentWithout the storage battery, a starter, the generator and about 17 kilometres of a copper wire in yours Mondeo does not work almost ANYTHING – at least, not координировано: at the discharged battery the starter strikes, without a starter the engine is silent, without the engine the generator has a rest, and without a copper wire all three leading players will be out of work.
Electric current – «vital juice» for engine management
As well as all cars, you Mondeo during movement eats electric energy. Its subsystems, such as engine management, system of injection of fuel or illumination depend on "current". And at such dependence there is nothing surprising that many drivers connect the unpleasant incidents with a trio: the accumulator – the generator – a starter. Their reason is covered under an engine cowl, that is in places of residing and work of these three main actors and their periphery more often. In their justification it is possible to tell the following: working conditions dominating there are not so ideal: sometimes happens coldly, more often too hot, at times it is damp, and sometimes and it is wet. Besides, many consumers of a current sit in exhibiting places – therefore failures in onboard the electrical engineer are already actually programmed. Besides it, and the storage battery capitulates sometimes to a hard frost or a strong heat.
To eliminate simply – small troubles in onboard the electrical engineer
After the heard lecture on the given chapter, certainly, no convincing arguments any more occur capitulating to "the dead" switch or "a black" bulb. More often the rusty wire connection which has got "on the way" or rusty contact "are got mixed up" in it. The majority of malfunctions in onboard the electrical engineer can be eliminated simple means. Even in the event that you are not «the testified strippen-worm» and you do not have all ambitions to become the professional electrician.

The basic concepts electrical engineers Electric pressure (current) flows only in the closed electric chain. Electric chains consist of the manufacturer of a current (for example, the accumulator, the generator), the consumer (for example, a lamp накаливания, a starter, the electric motor) and cable bunches with their separate wires. Cable bunches realise connections between manufacturers and current consumers.
The basic concepts electrical engineers visually are explained by the following example: imagine a water supply system in which under certain pressure water of certain quantity from point And (manufacturer) in point In (consumer) flows. Something similar occurs and in electric chains of yours Mondeo. For example, when at door opening automatically in salon light is switched on.
Pressure: It corresponds to pressure of water in a waterpipe. Dimension of pressure – Volt ().
Current: Corresponds to the expense of water which proceeds for the certain period of time through the pipeline. Dimension of a current – Ampere ().
Capacity: pressure Product on a current strength. It also defines, how many capacities are received by the electric consumer from the manufacturer of a current. It is set in Watts (Вт).
Resistance: It is possible to compare with запорным the water crane. If it completely to open, water free flows in the pipeline (resistance 0). The closed crane continuously raises resistance and so until it at all will not stop a leak (resistance). Dimension of this size the Ohm (W).
Wire: Corresponds to a water collector. The demanded thickness wires (section) depends on the consumer: control bulbs quite manage in the thickness of a wire in 0,5 мм2. On the contrary, such consumer as the starter, demands already a wire section 16 мм2 – in our example it would correspond to connection of the main pipeline. The thin wire quickly heats up – and pressure inevitably falls. Thereof, for example, headlights are reached any more by 12 Volt but only 10 or even 9,5 Volt is becomes appreciable by dim light. |

Instructions on the storage battery In Germany for purchase and recycling стартерной the storage battery some years instructions on «to work with the accumulator» operate. However all of them are yet known to the end user. Though this arch corrected similarly is addressed the seller, workers of a workshop and the end user. According to it the end user should utilise the old accumulator through the seller or a workshop. Return is carried out free of charge, only at new acquisition стартерной the storage battery special rules operate. In our review the most important points are presented.
On стартерный the accumulator which you get at the seller or in a workshop, the seller automatically charges «returnable pledge» at a rate of 7 euros. As corresponding acknowledgement at purchase you receive the receipt or mortgaging mark.
These rules contain the main exception: to you pledge if at purchase you return the old accumulator is not charged. If the seller or the workshop has already counted the mortgaging price for the old accumulator you receive the money back at a receipt presentation.
You can redeem your pledge at the seller only at purchase of the new accumulator. For this purpose you are obliged to transfer the old accumulator and the receipt (mortgaging mark).
The old accumulator, certainly, should not be identical with bought стартерной the storage battery: under the receipt you can give any стартерный the accumulator.
At purchase return the old accumulator for which you yet have not paid pledge, thus all the same, whence there is this accumulator: for the new accumulator the mortgaging price does not join in cost.
