What is the small wire on the positive battery cable?
There is also a smaller cable that goes directly from the alternator/battery output (B+) terminal directly to the positive terminal on the battery that supplies the electricity that charges the battery.
What would happen if you connected a wire directly from the positive side of a battery to the negative side of a battery?
Connecting one battery positive terminal to the other’s negative will cause a great surge of electric current between them. The batteries will then begin heating and a lot of hydrogen will be produced from a series of chemical reactions. This is even worse for lead-acid batteries that are the most common.
What is the positive battery cable connected to?
The positive battery cable connects the positive side of battery terminal to the vehicle motor starter and electrical system. The negative side provides grounding, or return path, back to the battery.
What happens when the battery is attached to the wire?
Connecting the two terminals of a battery is a bad idea. If done simply through a wire, would cause heavy current to flow through the battery. This current would heat up the battery and reduce battery life or might even discharge the battery depending upon the time for which the connection sustains.
Is there a secondary wire to the positive battery?
I have had this happen before, so I got out and took a look at the battery. In addition to the larger 8ga wire leading from the positive battery terminal, there is a secondary wire, maybe 16ga, with a fuse connected to it. I found that the end of the wire had turned turquoise with the copper corroding, until the wire was no more.
Is there a fuse on the positive battery terminal?
In addition to the larger 8ga wire leading from the positive battery terminal, there is a secondary wire, maybe 16ga, with a fuse connected to it. I found that the end of the wire had turned turquoise with the copper corroding, until the wire was no more.
What happens when I attach the negative battery cable to…?
If you connect the negative first, then the positive, if you happen to touch the wrench to something metal while it is touching the positive terminal, that’s a short – because the chassis is already connected to the negative battery terminal. Best case, there will be a very big, very bright spark followed by substantial swearing.
Is it possible to corrosion a battery wire?
Just have to adjust our thinking a bit and pay close attention to detail. The major pitfall to this method is, as has been mentioned, corrosion of the wiring is more of a possibility due to the proximity of that feed wire to the battery fumes.

What’s the difference between positive and negative battery cables?
4.2.2 Difference between Positive and Negative Cables. Positive battery cables are larger and red. They are used to connect the battery to the starter motor and the electrical system. Negative cable is smaller and black. It is used to ground the electrical parts and connect to the negative post of the battery.
Where does the positive battery cable go on a car?
The positive cable is red and connects to the battery’s positive terminal and the car’s motor and electrical system. 4.1.1Termination You can purchase a pre-terminated positive battery cable or use a crimper to terminate your connectors.
What does positive battery cable connect to?
What is the small wire on the negative battery terminal?
The smaller wire attaches to the body and is a shield ground. While the engine has many connections to the body they are not necessarily a tight connection. The small wire ensures a good connection.
Which battery post is positive?
Each battery has two metal terminals. One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-).
Are positive and negative battery cables the same?
Car battery cables are usually colored to match their use: red cables are positive, black cables are negative. Negative cables bolt directly to the body of the car or engine block, positive cables attach to the starter. The battery will have labels marked with a + and a – sign.
Where does the negative wire go from the battery?
The negative cable is normally black, and the positive cable is normally red….Negative Battery Cable
- One section goes to the engine and under hood area.
- The other section of the positive battery cable goes to the interior electrical distribution center.
Where do the positive and negative cables connect?
The positive cable connects on one end to the battery and on the other end to the large terminal on the starter solenoid. That is where everything picks up its power if off of the same terminal on the starter solenoid. Below are instructions for both the positive and the negative cables on both the 2.2L and the 4.3L motors with pictures, thanks
What’s the difference between positive and negative battery terminals?
Recognize the positive and negative terminals which are usually coloured. Black wires are for negative and red wires are for the positive terminal. In some cases, you will find both colours are the same. You need to find any type of red/black or plus/minus indicators/signs.
