When the drive belt moves, it turns an electrical current through magnetically induced energy. When you switch on the ignition, electricity starts from the battery, passes through the
Voltage Regulator, and ends up in the alternator. The diode rectifier changes the rotating motion of the drive belt into alternating current in the stator, which becomes direct current as it flows through the rotor. Most electricity goes to both charge the battery and run the car's electric systems. Some remains in the field wires to make the generator produce more energy. For cars with air conditioning, the alternator sits on a specialized mount, installed close to the number one front spark plug in the engine cavity. Take these steps: check the battery's positive and negative connections, wire up booster batteries right, don't use fast charging, disconnect battery cables before charging, and keep all connections clean and securely fastened. The belt should hold 22 pounds of pressure to shift by 0.35-0.43 inches when the belt is worn out, while a fresh belt needs 0.25-0.35 inches of movement under the same pressure. Take these steps to remove the alternator: disconnect the car's negative battery cable, remove the air cleaner if there's one, unplug all electrical connections, flip the adjusting bolt, take off the belt that turns it, and remove the whole thing. When changing brushes, you need a special iron that uses a soldering that has rosin in it. You also measure the brush lengths and put the new ones on right. To replace brushes in a Mitsubishi alternator, you first take out the whole assembly, open the front half of the unit, test brush length, and then put everything back together before reinstalling.
