Attention: If the following instructions are not followed, there is a danger of electrolyte splashing out of the battery. In addition, there is a risk of damage due to battery explosion or failure of parts of the electrical system.
Cross-section of auxiliary wires for starting the engine for gasoline and diesel engines. Immediately purchase wires of a larger cross section, because. they are more versatile.
Both batteries must be rated for 12V.
A discharged battery can freeze already at -10°C. Before connecting the auxiliary wires, the frozen battery must be thawed.
A discharged battery must be properly connected to the vehicle's on-board network.
Check the electrolyte level in the discharged battery, top up with distilled water if necessary.
Cars must be positioned so that they do not touch each other. Otherwise, even when the positive contacts are connected, the battery may leak.
Set the parking brakes on both vehicles. Put the gearbox in neutral (Automatic transmission - range P).
Switch off all current consumers. car engine- «donor» should idle during startup. This prevents the generator from failing due to power surges during start-up.
During start-up, do not bring an open flame or a burning cigarette close to the battery, so that the gases coming out of the battery do not explode.
Make sure that the auxiliary wires are not damaged by rotating parts such as a fan.
Connect auxiliary wires in the following order. 12. Connect the red wire to the positive contact in the engine compartment of the car with the battery discharged, having previously opened the protective cover. If this is a car of a different model, then connect the wire to the positive contact of its battery.
13. Connect the other end of the red wire to the positive contact of the charged battery.
14. Connect the black wire to the ground point on the shock absorber strut mount of the front suspension of the vehicle with the charged battery. If it is a different model car, connect the wire to the battery negative terminal.
4. Connect other end of a black wire to the same point of weight of the car with the discharged AB. If it is a different model vehicle, connect the wire to a good ground, such as a metal part on the engine block. In no case do not connect the wire to the negative terminal of a discharged battery, because. when sparks appear, an explosion of the battery may occur due to the ignition of the explosive gas inside it.
Caution: The terminals of the auxiliary wires must not touch each other, and the terminals of the positive wire must not touch.
Connection points on vehicles
Start the car's engine with the discharged battery and let it run. When starting, do not turn on the starter for more than 10 seconds, because. due to the high current, the clamps and the auxiliary wires themselves heat up. Pause for at least 30 seconds between start attempts.
Don't lean over AB - it's dangerous.
1 - positive contact of a discharged battery (A);
2 - positive contact AB- «donor» (IN);
3 - negative contact AB- «donor» (IN);
4 - ground point on a car with a discharged battery.
Attention: On BMW vehicles, before disconnecting the auxiliary wires, turn on the headlights, heated rear window and heater fan to avoid voltage surges from the voltage regulator.
After starting the engine, disconnect the wires in reverse order, i.e. first, a black wire from a car with a discharged battery, then from AB- «donor», then the red wire from AB «donor» and from a discharged battery.
