The alternator generates electrical energy from mechanical energy provided by the drive belt by the process of electromagnetic induction. When the ignition switch is turned on current travels to the charging system light or ammeter from the battery through the wiring to the voltage regulator to the alternator. Turning the drive belt forces the rotor to rotate within the fixed stator hence generating alternating current, which when passed through the diode rectifier is converted to direct current which is usable. Most of this current recharges the battery and supplies the electrical system of the vehicle while a part of this, goes to the field windings of the alternator to increase its output. When the field windings reach a definite control voltage, the voltage regulator Short-circuits the circuit and retains the voltage stabilized. The alternator is located, close to no1 spark plug at the front side of the motor compartment and for models that have aac, is mounted on a rubber isolator on the driver side. Some of its safety measures include correct polarity connection when re-charging the battery, correct booster battery connections, NO 'quick charge', batteries' connection should be disconnected during charging, and cleanliness of all electrical contacts plus tightness on the alternator equipped automobiles. For belt tension adjustment, a force of 22 lbs. should provide a deflection of 0.35-0.43 in. for a used belt and 0.25-0.35 of the width of the body panel material used in the belt. for a new belt. The removal and installation include detachment of the negative cable, sometimes detachment of the air cleaner assembly, separation of electrical connectors, alteration of the alternator adjusting bolt, and detachment of the alternator belt and unit. Brush replacement involves using a rosin core soldering iron in order to avoid corrosion, counting the number of brushes required and on how it is to be done to ensure correct positioning of the new brushes. For Mitsubishi type alternators, some of the procedures involve pulling out the alternator, disconnecting the drive end housing and the rotor rear housing, checking brush length and putting the alternator back in place and then reinstalled.
