The positive side of the battery is connected to the starter solenoid which is just a high current relay for the starter. It is also connected to the hot all the time bus which is a wire of the same starter solenoid that feeds the fusebox.
Negative side of battery is connected to the metal chassis of the auto and/or the engine block. Negative side is also called ground. This technique saves on usage of wire. The autos metal frame is literally used as one big black wire to give all electrical loads in the auto a close point to get to ground.
Yes connect the positive first to the positive battery post, and then connect the negative ground to the engine somewhere and not to the battery.
No, you do not connect battery positive to positive. When connecting batteries, you should connect the positive terminal of one battery to the positive terminal of the other battery only in specific configurations like parallel connections. In most scenarios, such as jump-starting a car, you connect the positive terminal of the dead battery to the positive terminal of the live battery and the negative terminal of the live battery to a ground point on the dead battery. Always follow proper safety protocols to avoid short circuits or damage.
Connect the Positive + battery cable to the positive + battery post first. Then connect the Negative - cable to the negative - battery post.
You connect the positive terminal first.
First off you must have the same type batteries. Connect the positive post of the first battery to the positive post of the second battery. Then connect the negative post of the first battery to the negative post of the second battery. Now connect the positive post of the first battery to the positive connection on the vehicle. Then connect the negative post of the first battery to the negative cable of the vehicle. Click the link for a diagram.
The positive
Connect a battery charger to battery positive to positive negative to negative
Connect them together in Series. Connect the negative post of one battery to the positive post of the other battery. Then connect the negative charger cable to one negative battery post and the positive to the positive post of the other battery.
Connect positive to positive post (red) on the battery and connect the negative to a place on the engine away from the battery.
The man said it Always connect the positive + cable first to the battery. Then connect the negative- cable to the engine somewhere. Never connect the negative cable to the battery itself. Batteries vent hydrogen gas and which can ignite with the slightest spark. For this reason never, ever, connect the negative first and never connect the negative to the battery.
You don't, you connect to the battery from the battery of another car. Use the positive cable to connect the two positive electrodes and the negative to connect the two negative electrodes.
Connect the positive clip of the charger onto the positive post of the dead battery. If the battery is located inside of a vehicle, connect the positive charger clip to a grounded surface--like an engine block--on the vehicle.
