Connect the negative cable first.
When jump-starting a car battery, you should connect the positive terminal first.
When jump-starting a car, you should connect the red jumper cable to the positive terminal of the dead battery first.
When a car battery in connected to itself (i.e. You connect jumper cables onto a battery and then connect the other two connectors to each other), you create a continual circuit with the battery and nothing else. A similar effect is when you hold a 9 Volt battery to your tongue and you feel a small but continual "zap". Imagine this effect, but much greater. Sparks will appear when the connectors are first connected. Warning: Do not do this. This will damage your car battery. The only reason you should connect a car battery through jumper cables is to connect it to another car's battery in order to "jump" a car.
You should connect and disconnect the negative post first. This way, if your tool touches ground when you work on the positive post, you don't short circuit the battery.
You connect the positive terminal first.
You do not recharge your car battery with another car, when you connect the batteries together to get your car started, it is called jumping it, and only partially gets the battery working again. It should not be attempted if you do not know what you are doing because it can be dangerous.
To jump start a car, first connect the red positive cable to the positive terminal of the dead battery, then connect the other end of the red cable to the positive terminal of the working battery. Next, connect the black negative cable to the negative terminal of the working battery, and finally connect the other end of the black cable to a metal surface on the car with the dead battery, away from the battery. Start the working car and let it run for a few minutes before attempting to start the dead car. The red cable should be connected first.
You don't, you connect to the battery from the battery of another car. Use the positive cable to connect the two positive electrodes and the negative to connect the two negative electrodes.
Disconnect the negative cable first when disconnecting a car battery
Disconnect negative cable first from old battery and connect it last when installing new battery.
Connect the Positive + battery cable to the positive + battery post first. Then connect the Negative - cable to the negative - battery post.
No, you connect the to an amplifier.
