DeutschAssuming that you are referring to the cables used for jump-starting a truck's battery, here are the steps to use them properly:
Park the donor vehicle (the vehicle providing the jump-start) facing the recipient vehicle (the truck with the dead battery) and make sure both vehicles are turned off.
Open both hoods and locate the batteries. Ensure that the batteries are in good condition, free of corrosion and there is no leaking acid.
Take the positive (red) cable and connect one end to the positive terminal of the donor vehicle's battery and the other end to the positive terminal of the recipient vehicle's battery.
Take the negative (black) cable and connect one end to the negative terminal of the donor vehicle's battery. Then, attach the other end of the negative cable to an unpainted metal surface on the recipient vehicle's engine block, away from the battery and fuel system.
Check the connections to ensure they are secure and not touching any moving parts.
Start the donor vehicle's engine and let it run for a few minutes to allow the battery to charge the dead battery.
Attempt to start the recipient vehicle. If it starts, let both vehicles run for a few more minutes before disconnecting the cables.
Disconnect the cables in the reverse order of how they were connected. First, remove the negative (black) cable from the recipient vehicle's engine block. Then, remove the negative cable from the donor vehicle's battery. Next, remove the positive (red) cable from the recipient vehicle's battery, and finally, remove the positive cable from the donor vehicle's battery.
Keep the recipient vehicle's engine running for at least 20 minutes to allow the battery to recharge fully before turning it off.
It is essential to follow these steps carefully to avoid damaging the electrical system of either vehicle or causing a fire. If you are not comfortable or familiar with using truck cables, it is recommended to seek assistance from a professional mechanic or towing service.
