The red battery cable is the positive one. The positive cable supplies the voltage to the starter and the main power center, then distributes it to the rest of the vehicle. The negative (black) cables supply the ground to the entire vehicle, which is what makes the circuit complete and allows the electricity to work.

The red cable is the positive and the black cable is the negative. The positive post is slightly larger.

Red cable to positive, black cable to negative.

Red/positive cable to red/positive cable. Black/negative cable to black/negative cable. The battery is under the cover in front of the air cleaner.

Black is negative and Red is positive.

Audio battery???? If you mean Auto Battery then Red Positive (+) RED cable goes to Positive (+) post on battery. Black Negative (-) cable goes to Negative (-) post.

Red, positive + cable to Positive + battery terminal. Black, negative - cable to Negative - battery terminal.

I assume you're asking how can you tell which is positive and which is negative? The red cable is positive in the black cable is negative. But if they are not color-coded the positive battery post is slightly larger than the negative battery post. If you try to connect the negative cable to the positive post it would be a tight fit and if you connect the positive cable to the negative post it would be loose.

The (Red) positive post is larger than the (Black) negative post and on almost every battery I have even see the + & - are embossed on the battery. The red, positive battery cable will go from the battery to the starter. The black, negative cable will connect to ground.

Red is positive. If they are both black then the cable that is connected to ground is negative and the other cable is positive.

On the battery is marked - or +. The red cable is positive and the black is negative.

No one is negative and one is positive charge

Connect the positive + red charger cable to the positive + red battery post. Then connect the negative - black charger cable to the engine somewhere. Most engines have something metal sticking up that you can connect to. Do not connect the negative charge cable to the negative battery post, always connect it to the engine.

There are typically two cables, one is usually red and the other black. The black cable attaches to the negative terminal on the battery and the red wire connects to the positive terminal on the battery. When removing the battery from the vehicle always remove the negative cable from the battery first. When installing the new battery always connect the negative cable to the battery last.

red is positive on a negative ground system

Something is on drawing power from the battery. Always connect the positive cable first and the negative cable last.

Connect the positive (+) Red cable from the charger to the positive (+) post of the battery. Now connect the negative (-) Black cable to a metal part of the engine. Do not connect to negative battery post. Plug the charger in. Unplug the charger before removing the cables. Disconnect the negative cable first.

The positive battery cable will be going from the positive terminal of the battery over to the starter solenoid. The negative battery cable goes from the negative battery post to either a bolt on the generator upper bracket or the side of the engine block. Typically, the positive cable is red, and the negative is black, but people do all sorts of odd things to their cars, like have the wrong colored battery cables, so, go by how they are routed, not by what they look like.

the red cable if there is no red cable usuallly the thicker cable is positive if that does not work look under your vehicle for the starter and fallow the thick wire back to your battery and that is you positive cable.

More often than not, the red cable hooks up to the positive post on the battery. There should be a mark on or by each battery post to indicate whether it is the positive (+) or the negative (-) post.

The positive cable is connected to the alternator and starter. The negative cable is connected to the chassis or engine ground. Positive is red and negative is black. The positive post is slightly larger than the negative post.

connect the positive (red) cable first then negative (black)

In most properly wired cars, a red cable goes to the positive terminal on the battery, and a black cable goes to the negative terminal. If color coding doesn't work, negative is the ground cable, positive is where your power is going.

The post with the red cable attached to it. The positive post is slightly larger than the negative post. + & - is normally printed on the top of the battery next to the post.

Disconnect the positive (+ / red) cable first. Then disconnect the negative (- / black) cable. Do not let one touch metal when other on battery. Take off brackets holding battery and remove. Replace with new battery, put in brackets... attatch cables, negative first, then positive.
