Charging System Components
Never operate the alternator without the battery in the circuit. Making or breaking an alternator connection with heavy load on the circuit can cause damage to the regulator.

(8) Fan.The alternator is driven by the crankshaft pulley through a belt that is a Poly-vee type. This alternator is a three-phase self-rectifying charging unit. The regulator is part of the alternator.This alternator design has no need for slip rings or for brushes. The only part of this alternator that moves is the rotor assembly. All of the conductors that carry current are stationary. The following components are the conductors: the field winding, the stator windings, six rectifying diodes and the regulator circuit.The rotor assembly contains many magnetic poles. These magnetic poles look like fingers with air space between each of the opposite poles. The poles have residual magnetism that is similar to permanent magnets. Permanent magnets produce a small amount of magnetic lines of force (magnetic field) between the poles.As the rotor assembly begins to turn between the field winding and the stator windings, a small amount of alternating current (AC) is produced in the stator windings. The alternating current is produced from the small magnetic lines of force that are created by the residual magnetism of the poles. The AC is changed into direct current (DC) when the current passes through the diodes of the rectifier bridge. Most of this current provides the battery charge and the supply for the low amperage circuit. The remainder of the current is sent to the field windings. The DC current flow through the field windings (wires around an iron core) increases the strength of the magnetic lines of force. These stronger magnetic lines of force increase the amount of AC that is produced in the stator windings. The increased speed of the rotor assembly also increases the current output of the alternator and the voltage output of the alternator.Regulators

Regulator assemblyThe voltage regulator is a solid-state electronic switch. The voltage regulator senses the voltage of the system. The regulator then uses switches to control the current to the field windings. This controls the voltage output in order to meet the electrical demand of the system.Alternator

The alternator is made up of the following components:

heat removal assemblies
the brush and holder assembly
the regulatorThe rotor assembly has the field windings. The field windings are wires around an iron core. The field windings create magnetic lines of force when direct current (DC) flows through the windings. As the rotor assembly begins to turn, the magnetic lines of force are broken by the stator. This creates an alternating current (AC) in the stator.The rectifier has diodes which change the alternating current (AC) from the stator to direct current (DC). Most of this current accomplishes these two activities:
The current charges the battery.
The current supplies the low amperage circuit.The remainder of the direct current (DC) is sent to the field windings through the brushes.Regulator Kit

Solenoid
A solenoid is an electromagnetic switch that performs two basic functions:
The solenoid closes the high current starter motor circuit with a low current start switch circuit.
The solenoid engages the starter motor pinion with the ring gear.
Illustration 5 g00292316
Typical solenoid schematicThe solenoid has windings (one set or two sets) around a hollow cylinder. A plunger with a spring load device is inside of the cylinder. The plunger can move forward and backward. When the start switch is closed and electricity is sent through the windings, a magnetic field is created. The magnetic field pulls the plunger forward in the cylinder. This moves the shift lever in order for the pinion drive gear to engage with the ring gear. The front end of the plunger then makes contact across the battery and across the motor terminals of the solenoid. The s
