When resistance increases in an electrical circuit:

Current flow will also increase

The amount of current flowing will depend on the size of the wires

Current flow will not be affected

Current flow will drop

Voltage regulation is needed in the charging system to:

Prevent the battery from discharging when the engine is off

Prevent overcharging of the battery

Reduce the alternator load on the engine

Allow for extra electrical accessories to be added to the vehicle

As a vehicle ages various electrical connections as well as the wiring in the starting and charging systems can become loose, worn, corroded, burnt, rusted and broken. These forms of resistance can affect proper operation of a starter or alternator. A reliable method for testing the connections and wiring for these types of problems is:

An Amperage test

A Battery test

A Charging system output test

A Voltage drop test

The Starting System has 2 circuits they are the:

Motor circuit and the Ground circuit

Insulated circuit and the Power circuit

Motor circuit and the Control circuit

Ground circuit and the Control circuit

The Alternator is one part of the charging system, other critical components of the charging system include the:

Battery, Fuses, and the Starter Relay

Ignition Switch and the Diodes

Battery, Drive belt, Fuses, and Control Circuit Wiring

Solenoid, Connecting Wiring, Battery, and Anti-Theft system
