2. Charging System This is the heart of the electrical system. It consists of three main components: the belt-driven alternator, various electrical circuits, and a voltage regulator. The alternator supplies power to the electrical system and recharges the battery after your car has started. Just like it sounds, the voltage regulator controls the voltage, keeping it within the operating range of the electrical system.
A small crack in a mirror will cause most people to dispose of a nearly perfect mirror when in reality they could easily repair the crack. Use a basic glass repair kit to fix a crack in the glass surface and extend the mirror's life. Glass repair kits are available at auto supply stores; the kit includes resin, film and stabilizers.
