A guide to Auto Electrical Components
Your car uses an extensive electrical system just to produce, store, and distribute all the electricity it requires to allow it to operate.
The Battery
The battery is used to store power for starting, and for running auxiliary devices such as clocks, radios and alarms when the engine is off.
Most batteries last between 3 and 4 years depending on brand and design. |

The Starter Motor
A combustion engine must be set in motion by an external force before it can power itself. This is performed by the "Starter".
Starter motors rarely fail without warning - symptoms such as turning the engine slowly, jamming and intermittent operation will usually occur before total failure. If you start to experience any of the above symptoms action should be taken as soon as possible to remedy the situation before you get stranded.

The Ignition System
Your engine mixes air and fuel, then adds a spark to make the explosion. This spark ignites the air-fuel mixture, and is referred to as the ignition.
This ignition takes place thanks to a group of components working together, otherwise known as the ignition system. The ignition system consists of an ignition coil, distributor, distributor cap, rotor, plug wires and spark plugs.
Older systems used a points-and-condenser system in the distributor, newer use an ECU, a little brain in a box, to control the spark and make slight changes in ignition timing. |

The Ignition Module
The computer that directly regulates your ignition system is called the ignition module, or ignition control module.
There is no maintenance or repair procedure for the module, other than replacement.
