The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
the positive side, the negative side is usually just a ground
When jumping two automotive batteries, connect the positive () cable to the positive terminal of the dead battery and the other end to the positive terminal of the live battery. Then, connect the negative (-) cable to the negative terminal of the live battery and the other end to a metal surface on the car with the dead battery, away from the battery.
The positive terminal of a battery is typically located at the end with a plus sign () symbol.
Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
If you have the fan removed from the car, you can just quickly use jumpers to connect the negative terminal of the fan to the negative terminal of the battery, then connect another jumper to the positive terminal of the fan,and with insulated hands(!) touch the other end to the positive terminal of the battery. If the fan runs, it's fine.
To safely jump a car when the positive terminal is red, follow these steps: Connect the red (positive) jumper cable to the positive terminal of the dead battery. Connect the other end of the red jumper cable to the positive terminal of the working battery. Connect the black (negative) jumper cable to the negative terminal of the working battery. Connect the other end of the black jumper cable to an unpainted metal surface on the car with the dead battery. Start the working car and let it run for a few minutes. Try starting the car with the dead battery.
The top of a battery is called a carbon rod, which is on the positive terminal.
To jump-start a Volvo XC90, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the dead battery's positive terminal and the other end to the donor battery's positive terminal. Next, attach the negative (black) cable to the donor battery's negative terminal and the other end to a grounded metal part of the XC90, away from the battery. Start the donor vehicle, then attempt to start the XC90.
To jump-start a 2006 Chevy HHR, first, ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the working battery. Next, connect the negative (black) jumper cable to the negative terminal of the working battery and attach the other end to a grounded metal surface on the dead vehicle (not directly to the negative terminal). Start the working vehicle, let it run for a few minutes, and then try to start the HHR.
To connect a wire to make a bulb light up, you need to complete an electric circuit. This involves connecting one end of the wire to the positive terminal of a power source (such as a battery) and the other end to the bulb's positive terminal. Then, connect the negative terminal of the battery to the negative terminal of the bulb to complete the circuit and allow electricity to flow, causing the bulb to light up.
The short answer is that they don't. But that doesn't help you much. Electrons flow from the negative terminal to the positive terminal. Why? Negative and positive (opposite) charges attract each other, and like charges repel each other. So you can think of the positive charged end pulling electrons towards it, as well as the negative charged end pushing electrons away from it. Water makes a good analogy, the battery is a pump, so there is high pressure on the outlet of the pump ( the negative terminal ) through the pipes and whatnot, ( the wire and whatnot) to the inlet of the pump ( the positive charged end ).
To jump start a 2003 Dodge Intrepid, first, ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the working battery. Next, connect the negative (black) cable to the negative terminal of the working battery and attach the other end to a grounded metal surface on the Intrepid, away from the battery. Start the working vehicle and then attempt to start the Intrepid.
