The engine light comes on and off for a variety of reasons, but the most common reason is that your car has an electrical problem. The next time you notice your engine light come on or go off, check out these other possible causes to make sure it's not something more serious.
The first thing to do when your engine light comes on is to check your battery. If the battery is weak, it could be causing problems with the ignition system. When the battery voltage drops below 12 volts, the computer will shut down the ignition system until the battery recovers. This can cause the engine light to come on and off as the computer tries to restart the ignition system.
A loose connection in the wiring harness could also be causing this problem. Check all connections between the battery and the rest of the vehicle. Also look at the connectors on the back of the instrument panel. They may have become loose over time.
Another possibility is that there is a short circuit somewhere in the electrical system. To find out if this is the case, disconnect the negative terminal from the battery and turn the key to "on." Then, start the engine and listen for any unusual sounds. If you hear anything, then you know there is a short circuit. You'll need to replace the faulty component before you can continue driving.
If none of these solutions work, then you should take your car to a mechanic who specializes in diagnosing electrical problems.
How Does A Car Battery Work? Batteries are one of those things that seem like they should just work, but don't always. There are many different types of batteries used in cars today, including lead acid, nickel metal hydride (NiMH), lithium ion, and even electric vehicles. Each type of battery has its own advantages and disadvantages. Here we'll explain how each type works so you can decide which kind of battery would best suit your needs.
How does a car battery work?
Lead Acid Batteries: Lead-acid batteries were originally developed during World War II by General Motors to power aircraft engines. These early batteries had a number of drawbacks, however, such as being heavy, having low energy density, and requiring frequent recharging. In addition, lead-acid batteries contain sulfuric acid, which is highly corrosive. As a result, lead-acid batteries are very dangerous to handle and dispose of properly. Today, lead-acid batteries still dominate the automotive market because they're inexpensive, easy to use, and reliable. If you want to know about Dependable Car Care, then you are at the right place.
Lead-acid batteries consist of two basic parts: the positive electrode and the negative electrode. Both electrodes are made up of plates coated with a paste containing lead oxide and water. The plates are separated by a porous separator material. During charging, the electrolyte dissolves into the plates and creates an electrochemical reaction. This process produces electricity.
When the battery discharges, the opposite happens. Water molecules break apart into hydrogen ions and oxygen ions. The hydrogen ions move through the electrolyte to the positive plate while the oxygen ions go to the negative plate. At the same time, electrons flow through the external circuit to complete the discharge cycle.
Nickel Metal Hydride Batteries: Nickel metal hydride batteries are similar to lead-acid batteries except that they use nickel instead of lead. Because nickel is less reactive than lead, NiMH batteries require much lower maintenance than their lead-acid counterparts . They also have higher energy densities than lead-acid batteries. However, NiMH batteries do not last as long as lead-acid batteries.
Nickel metal hydride batteries consist of two basic components: the positive electrode and negative electrode. Like lead-acid batteries, both electrodes are made up of a series of plates coated with a mixture of active materials.
