Cause the battery to explode or damage the electrical system in the car.
The negative terminal of a battery has a - sign and positive terminal has a + sign.
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.
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
The negative battery terminal is on the battery. They don't have a wire coming from it like they do the positive. For charging purposes, the engine block acts as the battery ground. When disconnecting the negative at the battery, the negative terminal usually has a black wire and the positive has a red.
The positive + terminal is slightly larger.
Two. The positive terminal, and the negative.
Red, positive + cable to Positive + battery terminal. Black, negative - cable to Negative - battery terminal.
There are 2 battery terminals. A positive or hot and a negative or ground. The positive is slightly larger than the negative.
If we go for the diagramatic representation then battery positive is represented by the long terminal and battery negative is represented by the short terminal then the direction of the current is given by an arrow from positive terminal to negative terminal (Therotically electrons flow from negative to positive but we represent current flow from positive to negative. This is the sign convention )
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
Disconnect the negative - terminal first, then the positive + terminal. Unfasten the battery hold down clamp. When reinstalling the terminal connections connect the positive terminal first.
