Stages of work
Move the booster vehicle as close as possible to the dead battery. The booster cable should be conveniently located between the two batteries.
In the vehicle requiring assistance, turn off all electrical consumers.
In the first step, connect the positive terminals with the red auxiliary cable. Always connect the discharged battery first and then the charged battery.
Then connect the black auxiliary cable to the negative terminals of both batteries. If the cable is not long enough, use a reliable ground connection in the engine compartment.
Start the engine in the assisting vehicle, let it run at medium speed. In this case, the generator already supplies sufficient voltage.
Start a car with a dead battery. If the engine does not start right away, pause every time after several attempts. Otherwise, the starter may overheat. During pauses, the voltage between the batteries is already equalized. While the partner's engine is running, this does not harm the starter battery.
As soon as the engine starts, with the engine running, disconnect first the black auxiliary wire on the negative pole of the empty battery and then on the pole of the full battery. Do the same with the red wire.
Charge an empty battery at slightly increased revs for the first 30 km.
