Start of the engine from the auxiliary power supply

At engine start do not use auxiliary aerosols!

It is necessary to observe an order of connection of the auxiliary starting battery, otherwise there is a danger of a poisoning with gases allocated in the course of gymnastics. Besides, there is a danger травмирования owing to possible explosion of the storage battery or damage of onboard electronics of the car.


1. The cross-section section of a starting cable for petrol engines in volume to 2.5 l should make not less than 16 мм2 (corresponds to diameter about 5 mm). For diesel engines or petrol engines in volume more the cross-section section should make than 2.5 l not less than 25 мм2. The cited data concerns the car with the discharged storage battery. The cross-section section, as a rule, is underlined on cable packing. It is recommended to buy a starting cable with the isolated clips section 25 мм2 as such cable will approach for engines and smaller volume.
2. Both storage batteries should have pressure 12 Century
3. The discharged storage battery can already freeze at temperature - 10С. Before joining of a starting cable the frozen storage battery should be necessarily defrozen.
4. The discharged storage battery should be included in a car network according to the instruction.
5. Check up level of electrolit of the discharged accumulator room of the battery. If necessary add the distilled water.
6. Cars should be on distance from each other, excluding their contact. Otherwise, after connection of positive poles the chain will become isolated.
7. On both cars tighten lay brakes. The gear change lever establish in position of a neutral course, at automatic transmission establish the selector in parking position “Р”.
8. Switch off all consumers of the electric power.
9. The engine of the car feeding the storage battery, in the course of start-up should work necessarily on single turns. Thus, damage of the generator owing to throws of pressure in the course of start is excluded.
10. Do not suppose near to the storage battery of presence of fire or a burning cigarette as in the course of a charge from the storage battery combustible gases are allocated.
11. Watch that the starting cable has not been damaged by rotating details of the engine, for example, the cooling fan.

The starting cable joins in the following sequence:


1. The cable of red colour joins a positive pole in an impellent compartment of the started car.

Preliminary cast away a cover. If the started car is not car BMW of 5th series, the cable joins a positive pole of the storage battery.

2. Other end of a red cable joins a positive pole of the feeding storage battery.

3. The black cable joins a weight point on an amortisation rack of the feeding car.

Is better to use for this purpose the metal part reliably connected to an impellent compartment. If the car is not car BMW of 5th series, the cable joins a negative pole of the storage battery.

4. Other end of a black cable joins a weight point on the right amortisation rack of the fed car. If the fed car is not car BMW of 5th series, attach a cable to a weight point. Is better to use for this purpose the metal detail connected by a carving with the block of cylinders. Under adverse circumstances, in case of joining of a cable to a negative pole of the discharged accumulator room of the battery because of formation of a spark and allocation of combustible gas the battery can blow up.

Contact of plugs of a starting cable among themselves after joining of cables is not supposed. For this reason positive plugs should not concern weight points (bodies or the chassis).

5. Points of joining for cars with the storage battery in an impellent compartment:

Connect wires for start of the car from an auxiliary source in an order specified in illustrations by numbers (pay attention that the wire going from the negative plug of the auxiliary battery, is not connected to the negative plug of the sat down battery)

1 — a positive pole (+), the fed storage battery ()
2 — a positive pole (+) the feeding storage battery ()
3 — a negative pole (-) the feeding storage battery ()
4 — a weight point () on the started car.

Start the car engine (the discharged storage battery) on single turns. At start a starter include not longer 10 with as owing to the big current consumption clips and a cable can be warmed up. Between separate start-up do a break not less than 30 with.

Be not declined over the storage battery. Danger of a poisoning!

At cars BMW before switching-off of a starting cable include illumination, heating of back glass and the maximum step of the fan of a heater to exclude occurrence of throws of pressure from a pressure regulator to consumers.

After engine start disconnect cables in return sequence: at first a black cable (-) at the started car, then at feeding. The red cable (+) is disconnected at first at the feeding car, then at the fed.
