The "+" sign is used to mark the positive post.
Connect the Positive + battery cable to the positive + battery post first. Then connect the Negative - cable to the negative - battery post.
NO! positive is red and black is negative negative is grounded to the frame of the car, and positive goes to the electrical components.
On any car, switching the battery hookups will most likely fry your battery.
If you have a post battery(the cable attaches from the top) the positive post is larger than the negative.
You could put them in parallel--wire positive to positive, negative to negative, then connect the positive and negative wires to the car. This would give you twice the current capacity, and you'd be okay because the car's only going to take as much power as it needs. If you wired them in series--positive on the first battery to the car, negative on the first battery to positive on the second, negative on the second battery to the car--you'd double the voltage and burn the car out.
Positive is either red or has a "+" symbol.
Remove the negative and then positive cables from the battery.
No, it is not possible to jump-start a car battery with a positive-negative connection. Jump-starting a car requires connecting the positive terminals of both batteries and the negative terminals of both batteries. Connecting positive to negative directly can cause damage to the electrical system.
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
Posittive first then the negative
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.
disconnect the negative (black) first then positive (red).
