Basic Knowledge Required

BASIC KNOWLEDGE
It is important that you have a basic knowledge of the following items. Without this basic knowledge, it will be difficult to use the diagnostic procedures.

Basic Electrical Circuits
^ You should understand the basic theory of electricity and know the meaning of voltage, current (amperes) and resistance (ohms).
^ You should understand what happens in a circuit with an open or shorted wire.
^ You should be able to read and understand a wiring diagram.

Use of Circuit Testing Tools
^ You should know how to use jumper wires to bypass components to test circuits.
^ You should be familiar with the Digital Multimeter (DMM).
^ You should be able to measure voltage, resistance and current and be familiar with the meter controls and how to use them correctly.

NOTE: When measuring the resistance to ground of a circuit or component, make sure to use a solid, unpainted chassis ground or the negative battery cable terminal.
