The fuse can get burnt because of the extreme heat resulting from the surge of electricity. You'll need to check your fuses and select the fuse s that may be associated with the car battery.
In most cases, it is the powertrain fuse. In some cases, the fuses may not be the only electrical part affected. If the alternator is damaged, it may need to be replaced and it could affect components that were connected to it. If the electrical current is able to get to the car's computer system, you may need to replace that as well. Sometimes the battery is also damaged and no longer functions.
It will need to be replaced as well. In most cases jump starting a car will be safe to do, but to prevent any problems follow the guidelines outlined below:. When you jump start your car the wrong way, there are many things that could possibly happen.
The battery, jumper cables, and electronics will be damaged, including the fuse and the sensors. There is even a risk of explosion when the problem is at its worst. Once you realize that you did the wrong thing, you may be able to fix the problem on your own. In most instances, you need to check the fuse. Chances are, one of them is burnt. You can buy a replacement for this and your car will be up and running in no time. Have you ever tried using a battery charger to get your car to start?
This might help you figure out if your battery is salvageable or not. If your still not sure why your battery is dead, try reading this article. How to Solve any Problems Created. Tips When Jump Starting your Car. Jump Starting the Wrong Way: The Consequences Each car is a little different, but each has fuses that help protect the car. Damage to Components In the short video above, damage occurred to the fuse. Damage to Battery If a battery was connected momentarily the wrong way during a jump start, their will likely be a small amount of damage.
Damage to Jumper Cables Like the previous situation, incorrect contact with a jumper cable between two battery for a time will heat up your jumper cables. Damage to Alternator Sometimes a car has some components that might be on during a jump start.
Steps to Take. Connect the - negative cable clamp to the donor battery - negative terminal. Connect the - negative cable clamp to the dead battery - negative terminal. OR to be extra safe Connect the - negative cable clamp to a ground on your car away from the battery. If any gas from the battery is leaking, and a small spark occurs, an explosion could occur.
Let the dead battery charge for minutes. It depends on how drained it is. Don't forget yourself; burning yourself could also occur. That being said, jump starting your car isn't normally dangerous. What happens if you disconnect the positive terminal first?
By removing the negative battery cable you are disconnecting the battery from the chassis of your vehicle. If you begin to remove the positive side before the negative and your wrench would make contact with any part of the vehicle, then you could cause a short in the system.
How long do jumper cables last? Turn on the engine in the good car and wait two minutes. From there you'll remove the cable in the reverse order at which you put them on, and you'll let the car run for two more minutes before you get back on the road.
What happens if you touch jumper cables together? Deliberately Causing Sparks Some people are in the habit of tapping the free ends of jumper cables together when the other ends are connected to a battery; this can be extremely hazardous.
The 12 volts carried by a car battery are unlikely to cause injury, but the amperage can be extremely dangerous.
Does negative or positive connect first? Safety: Always remove the negative cable first, then the positive cable. When you connect the battery, connect the positive end first. What happens if you hook a battery up wrong? During the process of charging the battery, you may accidentally mix up the cables and put the wrong one on the incorrect terminal.
When this happens, it could damage the battery as well as other associated electrical components. If you reverse the polarity of the charger to the battery, the battery may explode. What happens if you put positive on negative?
Connecting the positive terminal of each battery to the negative terminal of the other battery will result in a huge surge of electrical current between the two batteries. The heat can melt internal and external battery parts, while the pressure from the hydrogen gas can crack the battery casing. Do you connect red or black first? Almost all drivers know that a car with a dead battery can be started by jumping it from a car with a charged battery.
Automotive batteries are designed to produce the high electrical current required to start the engine. This routine procedure can become dangerous if the jumper cables are connected improperly -- if the positive terminal on each battery is mistakenly connected to the negative terminal on the other battery.
Damage will result from very high current flow, and possibly from incorrect polarity on the "dead battery" vehicle. Connecting the positive terminal of each battery to the negative terminal of the other battery will result in a huge surge of electrical current between the two batteries.
