It will vary from car to car, but the neg is usually black, and has a "-" sign. Normally the positive terminal is larger than the negative terminal.
The red terminal on a car battery is the positive terminal which feeds electrical current to various devices. The black terminal is the negative, or ground, terminal which is attached to the car frame.
The DC electrical system of the car requires a positive and negative electrical conductors for each electrical device. Taking the example of a single lightbulb powered by the car battery, this could require a wire leading from the positive terminal of the battery to one terminal on the lightbulb and a second (return) wire leading from the other terminal on the lightbulb back to the negative terminal on the battery. Two wires are required - a positive and negative. To reduce the quantity of wires required, the negative "wire" is actually the car body. Hence there is a positive wire leading from the positive terminal of the battery to the positive terminal of each electrical device on the car and the negative terminal of each electrical device on the car is connected to the car body (a metal conductor). The body of the car is then connected to the negative terminal of the battery, completing the circuit. There are virtually no return wires. This works as cars use a low voltage (12 V). If they used a higher voltage, this system could result in electric shock from touching the car body.
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.
Cars in which the positive terminal of the battery is connected to the chassis. They require specially designed components built for positive ground cars. The usual configuration is a negative ground (the negative battery terminal connected to the car's chassis).
Cause the battery to explode or damage the electrical system in the car.
Assuming the vehicle has a negative earth You connect the positive lead first The reasoning When the positive lead is fitted first, if you dropped a spanner across the battery negative terminal to the car body all you would do is make the circuit. If you connect the Negative lead first, and you dropped a spanner across the positive battery terminal to the car body you would then have a dead short
your an idiot. what color is the negative wire for everything. BLACK!!!AnswerI think it is the Red one. Red is the color code for the positive terminal (also for your battery tender). Black or green indicates the negative terminal..
The positive connector on a lead acid battery is frequently not white. In the United States, the wire that leads to it is usually red. The black wire leads to the negative terminal. The positive terminal on the battery is always indicated by a plus, +, sign. The Negative terminal is indicated by a minus, -, sign. The negative terminal is usually attached to the body of the car. (Cars have a negative ground, except for 1935-1948 Fords.) The positive connector is usually attached to the solenoid and generator. So check the wire that comes from the battery to the solenoid. That is positive. Check to make sure it is connected +.
I'm not sure what you're asking but maybe its this: Red is Positive (+) and Black is Negative (-).
Put the solar panel in the sun;Attach the red wire of the panel to the positive terminal of the battery;Attach the black wire of the panel to the negative terminal.
Normally red or brown. The battery has a + stamped into it by the positive terminal. Follow the wires, on a modern car the positive will go to the alternator and starter. The negative wire (easier to follow) will go to the body/engine block
