Electrical Systems Fault Diagnosis

Course details

To provide technicians who carry out electrical testing or diagnosis on modern vehicle systems with a working knowledge of the test procedures that allows correct diagnosis of system/circuit faults.

Course Content: 

• The electrical values
• Electrical measurement
• Identification of typical circuit symbols and use of wiring diagrams
• Test methods for circuit Continuity, Insulation and Resistance
• Electrical properties and the testing of series and parallel circuits 
• Battery and Energy systems operation, testing and diagnosis
• Test methods for circuits using voltage drop measurement

Learning Outcomes: 

• Refer to a typical system wiring diagram, identify the electrical components and the current paths connecting them to the control unit(s) of the system
• Understand the important electrical test procedures for the electrical systems on a typical vehicle
• Carry out correct test procedures using voltage, resistance current and voltage drop measurements to determine circuit condition and identify faults which may be present in vehicle system circuits.

Course Requirements: 

Trainees should be qualified motor mechanics/automotive technicians
