We generally connect the red wire to the positiveterminal of a battery. The black is connected to the negative terminal. Naturally, no wiring connections should be attempted until a thorough understanding of the circuit being worked on has been made.
You connect the batteries in series Red charger lead to one red battery terminal, then the black battery terminal of that battery to the red battery terminal of the second battery. Then black battery terminal of the second battery to the black lead of the charger.
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 red battery wire goes on the positive + battery terminal no matter which side it is on. The black wire goes on the negative - terminal.
Positive is normally red.
It is usually red.
Red, positive + cable to Positive + battery terminal. Black, negative - cable to Negative - battery terminal.
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.
Attach the red wire to the positive terminal on the battery to be charged. This terminal is the first one built at this train station.
Remove the cover on the fuse box by pressing the tabs on either side, then find the remote positive terminal. Attach your red jumper cable to the terminal and the +ve terminal of the charged battery and the black cable to the -ve terminal of the charged battery and the -ve battery terminal or the chassis of the car to be jumped.
If you are asking what wrench to use to tighten or remove the terminal they are 5/16ths.
Positive is either red or has a "+" symbol.
The starter.
