A good thing with battery checking and trouble shooting is that you need very little technical equipment. All you need is a good, old Digital Volt Ohm Meter and a charger for the battery. Each auto battery manufacturer uses a certain color in the battery 'eye' which tells whether a charge is needed. This is a fast and easy way to alert you for re-charging. Check out your battery manufacturer's specification of the 'eye' and everything associated with it.
The charging system will normally consist of two major components: An Alternator which actually supplies the necessary electrical current in order to charge the battery, and a Voltage Regulator. The latter insures that the system does not overcharge the battery, and that the correct system voltage is maintained. Most vehicles produced within the last 20-30 years use a voltage regulator which is an integral part of the alternator itself. This article assumes that your vehicle uses this type of alternator.
