Modern cars are equipped with computers and injectors. For them, the best way to plant will be energizing to your machine from the battery to the other. For this there are special wire-clamp terminals. They are sold at any auto shop and very affordable. It's worth to buy them and store in the car, even if you have a new and stable car. You might help someone on the road, giving a jump start.
To make one car from another, put them together, but so that housing is not in contact. You must include a neutral speed and the Parking brake on each car. Secure the wire to the positive terminal outside the battery, then the other end attach to the "plus" worker. For simplicity, the "plus" terminals may be marked in red and minus are black. Then secure the cable on the "minus" infected battery, and then the corresponding terminal outside. Start the working car and leave it to work for 10-15 minutes. After that, not for instance operating a car, try to get one with the low battery.
If the car in whatever was necessary to make, and the wires no one, then you can resort to a permutation of the battery. Remove the batteries from the cars. Put a working battery in a car that failed to start. Do not attach it on the case and do not advance fixing of terminals. Start the car. Not suppresses the engine, carefully disconnect the working battery and place outside. Well secure it and the terminals. We perform these manipulations only if you have confidence in their knowledge and skills.
If the electronics of the machine allows, you can try to start it while driving. It is necessary to bring the vehicle in motion: request that you hauled on the rope, slide down by inertia from the sloping surface or ask help to your car pushed. When the machine is set in motion, turn the ignition switch to work mode and turn on the speed (better to limit first or second). This method is extremely harmful for machines with injected fuel and is conditionally prohibited.
