The cross-sectional area of the males should be about 16 mm², ∅ 5 mm, for gasoline engines with a working volume of up to 2.5 liters. For diesel and gasoline engines with a working volume of more than 2.5 liters, the cross-section of the male should be at least 25 mm². In this case, the battery of the "donor" car must be charged.
Both batteries must be 12V.
A discharged battery can freeze at temperatures as low as -10°C. A frozen battery must be defrosted before connecting the cable.
The discharged battery must be connected to the vehicle's electrical system.
Check the electrolyte condition in the discharged battery. If necessary, add distilled water.
Place the cars so that their metal parts do not touch.
Put both vehicles on the handbrake, gearboxes in neutral, and automatic transmission in position "P".
Disconnect all consumers.
The donor car must operate at idle speed.
Connect the males in the following sequence.
1. Connect the red cable to the positive terminal of the discharged battery.
2. Connect the other end of the red cable to the positive terminal of the donor battery.
3. Connect the black cable to the negative terminal of the donor battery.
4. Connect the other end of the black cable to ground, for example, the cylinder block of the car being started. This will eliminate losses. Under unfavorable circumstances, when connecting the cable to the negative of a discharged battery, the battery may explode due to the formation of a spark and the release of detonating gas.
Check again that the cable connections are secure and that they do not come into contact with moving parts such as the fan belt, etc.
Caution: Cables must not touch each other; cables must not touch the ground.
Start the engine of the car with a discharged battery and let it run. When starting, do not keep the starter in the on position for more than 15 seconds, since due to the high current consumption, the pole clamps and cables may heat up. Between starts, make a delay of at least 1 minute.
Let the donor car idle well to avoid generator failure due to peak voltages during startup. If the idle speed drops, give it some gas.
When starting, remove any open flame from the battery, as the battery produces flammable gas.
After starting, disconnect the cables in reverse order.
Caution: Failure to comply with these rules is dangerous to your health and the technical condition of the machine.
