CHARGING TEST: Let's take a look at the charging system. As this diagram shows, with the engine running, a belt which runs off the spinning fan pulley, turns the alternator which develops electrical current. The regulator, which is usually located inside the alternator itself, then sends, at the proper time, the appropriate amount of current via the ignition switch to recharge the battery. On some cars, the regulator is a separate unit and is located outside the alternator. Electrical system maintenance involves a periodic ignition system tune-up as well as making sure that all your wiring connectors are clean and tight paying special attention to alternator and battery connections. To avoid premature discharge of your battery, make sure connections are tight. Periodically, clean battery terminals and cables with a wire brush. In addition, periodically check connections at the solenoid or starter as well as at the alternator, distributor cap, spark plugs, coil and where connections attach to the frame and engine to make sure everything is clean and tight.
