Electrical System

The system in a motor vehicle that furnishes the electrical energy to crank the engine for starting, rechargethe battery after cranking, create the high-voltage sparks to fire the compressed air-fuel charges, and power the headlamps, light bulbs, and electrical accessories.




The vehicle electrical system includes the battery, wiring, starting motor and controls, generator and voltage regulator, electronic ignition, and electronic fuel metering. Also included may be a computerized electronic engine control system, an electronically displayed driver information system, various types of radios and sound systems, and many other electrically operated and electronically controlled systems and devices.


High Output Alternators

An alternator in an automobile is really an electrical generator that produces an alternating current to power the electrical system in the vehicle when the engine is running. It will also charge the battery on the vehicle. The electrical current that an alternator generates is used for the lights, fan, ignition, radio, etc.A high output alternator generates more power and amps at a higher rate than a normal alternator does. If your vehicle has added aftermarket electrical devices you will need a high output alternator for them to run correctly. For example if your vehicle has a custom sound system or an audiovisual system installed, after you bought the car, you will need a stronger high output alternator.A high output alternator uses a smaller pulley that allows it to improve the electrical output even when the engine is idling.




If you have installed a custom sound system in your vehicle, you will really need to upgrade to a high output alternator. Almost all stock alternators produce about a maximum of 60 amps. Almost half of these amps are used to run your vehicle. As a result the stock alternator will only leave you about 30 amps for your custom sound system. Usually a custom sound system will need about 120 amps to run it. Your battery will try to supply the amps but will only be able to do that for a short time. Then your voltage will drop and your sound system will not be able to continue to operate at its full potential. The way to solve this problem is to replace your stock alternator with a high output alternator. A very overlooked component toward an upgrade of a sound system .Excellent voltage stabilizer for a sound system upgrade and vehicles accessories.



An automotive batteryis a type of rechargeable battery that supplies electric energy to an automobile.Usually this refers to an SLI battery (starting, lighting, ignition) to power the starter motor, the lights, and the ignition system of a vehicle’s engine. This also may describe a traction battery used for the main power source of an electric vehicle.

SLI Battery



Automotive batteries, usually of lead acid type, provide a nominal 12- volt potential difference by connecting six gavantic cells in series. Each cell provides 2.1 volts for a total of 12.6 volt at full charge. Lead-acid batteries are made up of plates of lead and separate plates of lead dioxide, which are submerged into an electrolyte solution of about 35% sulfuric acid and 65% water . This causes a chemical reaction that releases electrons, allowing them to flow through conducters to produce electricity. As the battery discharges, the acid of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfhate. When the battery is recharged, the chemical reaction is reversed: the lead sulfate reforms into lead oxide and lead. With the plates restored to their original condition, the process may now be repeated.

Gel Cell



A gel cell battery is similar to an SLI style because the electrolyte is suspended, but different because technically the SLI battery is still considered to be a wet cell. The electrolyte in a GEL cell has a silica additive that causes it to set up or stiffen. The recharge voltages on this type of cell are lower than the other styles of lead acid battery.The gelled electrolyte won't spill, even if the battery is tipped upside down or cracked open. Gel batteries boast greater resistance to extreme temperatures, shock, and vibration. These types of batteries are widely used in car audio installations for these reasons. Always wear proper eye, face and hand protection when working with batteries, never hover over battery while boosting, testing, or charging. Place caution when working with tools and other objects to prevent accidental short circuit and arcing.
