You must remember to connect the wires on the same side of the terminals. As a consequence, a positive terminal connected to a positive terminal by a lined wire, and a negative terminal connected to a negative terminal by a wire without a line. The term "lined" means that the conductor is inside a metal sleeve called a "cladding."
The other type of wiring, which is used in secondary circuits such as lamps and appliances, is called "grounded". In this case, both ends of the cable are joined to ground (the metal frame of the house) or to a similar connection point instead of to separate terminals. This is important because if you connect positive to negative things will burn up! The term for this kind of wiring is "double-ended".
In conclusion, positive cables should be connected to positive terminals, and negative cables to negative terminals.
When connecting wires to a battery, connect the positive end first, followed by the negative. This will give you a good connection and prevent your battery from being damaged.
Positive terminals are connected by a red wire, whereas negative terminals are connected by a black wire. Because the ground wire in most American electrical systems is connected to the negative terminal, you may also notice a bare, flat braided wire running to the frame of the vehicle or object. This is the ground.
If you're working on someone's car, it's important to remember that the negative side of the battery is not the same as negative. The term "negative" refers to the circuit being broken when something is plugged into the socket. The "negative side" of the battery is actually the + side, which should be hooked up to a metal component of the car's bodywork if possible. If this isn't possible, then a metal box called a "battery carrier" can be used instead. This is what keeps the battery safe while it's disconnected from the car.
In conclusion, positive connections are white or silver colored wires, while negative ones are black or brown wires. It's very important to identify and label your wiring contacts correctly to prevent accidental connection of two opposite charges.
Connect the positive connection to the positive terminal of the good battery and the negative cable to the negative terminal. Care should be taken not to connect them to the wrong terminals.
Put the other end of the cable into another positive socket. You have now connected the third lamp in a series circuit.
To test if all is well, turn on all the lamps one by one. If each time you turn on a lamp you see another one go out, then both cables from good battery are connected to the correct terminals. Otherwise, check that both cables come from same socket (maybe ask someone to help you out). If they do, try another battery. If it works with another battery, then the problem lies within the damaged battery. In this case, you will need to replace it.
You can also connect negative to negative or positive to positive but not both at the same time. If you do, you will get a short circuit which will damage either the second hand lamp or the battery itself.
Short circuits can also occur if there are small pieces of metal within the sockets. You should check them regularly for wear and tear.
Each battery is equipped with two metal terminals. One is indicated positively (+), while the other is marked negatively (-). (-). Never connect the red cable to a vehicle's negative battery terminal or a dead battery. Always connect the red cable to the + terminal of another live battery of the same make and model as your vehicle. If you have more than one car or truck at home, there should be one positive cable per vehicle.
The term "negatively" means that if you were to connect this cable end first into a battery, it would record a negative charge. Conversely, if you were to connect it out last, it would record a positive charge. Negative cables are used in order to keep electric circuits "hot" so they will work properly. If all the cables from your circuit breaker to your vehicle's battery were always connected together, then even if one cable was disconnected, the system would still be hot enough to start automatically.
Cables are connected to vehicles' batteries in much the same way that jumper cables are connected to each other. However, instead of having both ends of the cable connect to other batteries of the same vehicle, only one end of the cable connects to the other battery. The other end of the cable remains attached to the first battery, thus completing an electrical connection. Cables can also be connected in parallel to increase the current flowing through them.
