Electronic Fault Diagnosis Course
This course teaches you to identify and solve problems in electronic systems efficiently and professionally. It gives you the tools and knowledge you need to diagnose faults with confidence, from reading schematics and understanding how circuits behave to using measuring instruments such as multimeters, oscilloscopes and logic analysers and applying a systematic method that takes you from the first symptom to a verified repair.

What is the Electronic Fault Diagnosis Course?
This short course teaches you to find and fix faults in electronic equipment with a structured method. You will study analog, digital, mixed, power and control circuits, the essential electrical quantities and the key components, and the typical failure modes, from short and open circuits to leakage, overheating, degradation and intermittent faults; how to use the digital multimeter, oscilloscope, adjustable power supply, signal generators and logic analysers safely on live and de-energized circuits; a systematic diagnostic routine with symptom gathering, visual inspection of boards, power supply analysis and signal tracing by functional blocks; and the diagnosis of analog and digital circuits, linear and switched-mode power supplies, power stages and electrical protections.
What sets this course apart: it replaces trial-and-error with a structured diagnostic method that you can apply to any piece of equipment; it combines theory of circuit behavior with hands-on use of the measuring instruments that every workshop and engine room relies on; it covers the full range from signal circuits to power electronics with MOSFETs, IGBTs and drivers; and it ends with a practical case in which you diagnose, repair, verify and document a real or simulated fault from start to finish.
Program highlights
- Applied electronics: circuit types, voltage, current, impedance and the key components behind every fault.
- Failure modes: short circuits, open circuits, leakage, overheating, degradation, intermittent faults and manufacturing defects.
- Instrumentation: multimeter, oscilloscope, adjustable power supply, signal generators and logic analysers used safely.
- Structured method: symptom gathering, board inspection, power supply analysis and signal tracing by functional blocks.
- Analog, digital and power circuits: amplifiers, buses, microcontrollers, switched-mode supplies, MOSFETs, IGBTs and protections.
- Final project: a complete diagnosis and repair of a real or simulated fault, verified and fully documented.

Questions about the Electronic Fault Diagnosis Course
It is the process of identifying the root cause of a malfunction in an electronic system or device, so that it can be repaired with certainty rather than by replacing parts at random.
Identifying the symptom. The course teaches you to receive the equipment, gather information on how and when it fails, and only then plan inspection and measurements.
The digital multimeter, the oscilloscope, the adjustable power supply with current limiting, signal generators and logic analysers, always with safety criteria for live and de-energized circuits.
Yes. The fourth module deals with linear and switched-mode power supplies, converters, regulators, power stages with transistors, MOSFETs, IGBTs and drivers, and electrical protections.
The course treats them as a specific failure mode and shows how a structured method, power rail analysis and signal tracing with the oscilloscope help you catch faults that do not appear all the time.
You take a circuit, piece of equipment or module with a real or simulated fault, formulate hypotheses, plan and carry out measurements, locate and repair the fault, and document the whole process with a final functional test.
Fully online, through a virtual campus available 24/7, with on-demand videos, discussion forums with the teaching staff and downloadable material for offline reference.
The course comprises 300 hours of study across 5 modules of about 60 hours each and ends with a final project. You can progress at your own pace within the schedule set when you enroll.
