Understanding automotive electrical systems is essential for diagnosing many car problems that cannot be solved with an OBD2 scanner alone.
This course introduces the basics of electrical diagnostics in a simple, practical way — even if you have no prior experience.
Video course
This training explains how automotive electrical systems work and how to test them using basic diagnostic tools.

What this course is about
This course focuses on the fundamentals of automotive electrical diagnostics.
It is designed to help you understand how electricity behaves inside a car and how to use that knowledge when diagnosing faults.
You will see how electrical measurements are used to confirm problems that cannot be verified using a scan tool alone.
Why electrical diagnostics is important
Many car problems have multiple possible causes, and not all of them can be tested with an OBD2 scanner.
In these cases, electrical testing becomes necessary.
Understanding voltage, current, and resistance allows you to:
- Confirm faults instead of guessing
- Test sensors and wiring
- Identify real causes behind fault codes
This is the step that separates basic scanning from real diagnostics.
What you will see inside
- Basic electrical concepts explained in simple terms
- How voltage, current, and resistance work in real circuits
- How electrical behavior changes under load
- Differences between series and parallel circuits
- How electrical faults affect circuit behavior
All concepts are demonstrated on real examples, not just theory.
Tools used in this course
The course introduces the most important electrical diagnostic tools step by step.
You will see how tools like:
- Multimeter
- Test light
- Clamp meter
- Oscilloscope
- Power probe
are used in real situations.
For beginners, only a basic multimeter is required to get started.
Practical approach
The focus of this training is not just theory.
Every concept is demonstrated on real circuits to show:
- How measurements are taken
- What values to expect
- How to interpret results
This makes it easier to apply the knowledge in real diagnostics.
Who this course is for
This course is designed for:
- Beginners in car diagnostics
- DIY mechanics
- Anyone who wants to understand automotive electrical systems
It is especially useful if you feel stuck when fault codes don’t give you a clear answer.
What you need
To follow this course, you only need:
- A basic multimeter
Additional tools are introduced gradually, but not required at the start.
Focus of this training
This course focuses on:
- Understanding electrical systems
- Learning how to take measurements
- Interpreting electrical data
It does not focus on advanced diagnostics procedures or specific repairs.
