AUTO ELECTRICAL BASICS Battery Maintenance Services
The battery in your car is is the source of energy energy for all the electrical components that your vehicle has. One of the main functions of the battery is to provide energy to the starter and ignition, but all of the other electrical equipment in your car relies on the battery as well.
A vehicle battery has several important fnctions! sch as"
Providing Providing power to the starter motor, gnition system, !uel system and other electrical devices during engine starting Storing energy

Providing power to electronic components as required when the vehicle is o" #$%ample& 'igital radios, cloc(s, door loc(s, alarms, vehicle computers, etc.)
*hen the engine starts running, the charging system ta(es over to provide electricity to the various vehicle electrical systems. The battery cable terminals connect the battery to the electrical system. To achieve optimal performance and avoid possible damage to your vehicle+s electrical system, you need to maintain your battery in good condition. The following procedures will help to ensure your battery is maintained in good condition&
-hec(ing the alternator belt tension -hec(ing the wear of the alternator belt -hec(ing the electrolyte level Tightening loose holddown clamps and terminals /emoving any visible corrosion

Starter motor or self starter or starter motor:
The electric starter motor or starting motor is the most common type used on gasoline engines and small Diesel engines.
The modern starter motor is either a permanent-magnet or a series-parallel wound direct current electric motor with a starter solenoid (similar to a relay) mounted on it.
When current from the starting battery is applied to the solenoid, usually through a key-operated switch, the solenoid engages a lever that pushes out the drive pinion on the starter driveshaft and meshes the pinion with the starter ring gear on the flywheel of the engine.
The solenoid also closes high-current contacts for the starter motor, which begins to turn. Once the engine starts, the key-operated switch is opened a spring in the solenoid assembly pulls the pinion gear away from the ring gear, and the starter motor stops.

Alternator (atomotive) Alternators are used in modern automobiles to charge the battery and to power the electrical system when its engine is running.

The starting system includes the battery, starter motor, solenoid, ignition switch, and in some cases, a starter relay.
A typical charging system contains an alternator (generator), drive belt, battery, voltage regulator and the associated wiring.
The charging system, like the starting system is a series circuit with the battery wired in parallel. After the engine is started and running, the alternator takes over as the source of power and the battery then becomes part of the load on the charging system.
