Title: Best Practices with Electude: Teaching Voltage Drop 



In the realm of automotive education, lab scopes and voltage drop diagnostics can present challenges for both instructors and students. Fortunately, innovative platforms like Electude have revolutionized the teaching process, making learning about lab scopes more accessible and engaging.Today, we will explore the key points discussed in a recent webinar, shedding light on effective strategies for teaching voltage drop using Electude’s interactive lessons and simulations.

Teaching Voltage Drop:

Electude offers a comprehensive lesson called “Fault Finding” that introduces students to voltage drop concepts. The lesson begins by teaching four ways to measure circuits: terminal voltage, applied voltage, voltage loss across the ground circuit, and voltage loss across the positive circuit. Through animated visuals, students learn how to use a manual range meter and identify voltage losses in simplified circuit diagrams.

By following the guided steps, students gain hands-on experience in diagnosing and troubleshooting faults. They encounter a defroster circuit and work through a series of four different faults, using the V1 through V4 method to analyze and rectify the issues. This practical approach allows students to apply their knowledge in a realistic setting and reinforces their understanding of voltage drop diagnostics.

Practical Exercise with Engine Simulator:

Electude’s interactive engine simulator provides highly practical exercises for students. For example, students can practice receiving a work order stating that the engine cranks but does not start. Using the simulator, they explore the main relay wiring to identify the underlying problem.

The simulation enables students to examine the vehicle’s diagnostic system, instrument panel, and fault codes. They focus on the ECM power relay circuit, testing for power output and applied voltage across the relay coil. By analyzing the voltage readings, they can pinpoint where voltage loss occurs in the circuit. In the example provided, the students discover that a faulty wire is causing a significant voltage drop, hindering the relay’s operation. By replacing the wire, the problem is resolved, and the engine starts successfully.

The Benefits of Electude’s Approach:

Electude’s approach to teaching voltage drop through guided self-discovery offers several benefits. The lessons provide a gradual progression from simple circuits to more complex scenarios, ensuring students grasp the fundamental concepts before tackling real-world situations. The integration of numbering systems, schematics, and manual range meters enhances the learning experience, bridging the gap between theory and practical application.

Moreover, Electude’s simulations and animations offer a unique and engaging way to teach difficult concepts. Instructors can utilize these tools to deliver interactive lessons, providing an immersive learning experience for students. The ability to simulate circuit behavior and interact with virtual components, such as meters and switches, fosters a deeper understanding of automotive diagnostics.


Teaching voltage drop and utilizing lab scopes in automotive education can be challenging. However, with Electude’s innovative educational platform, instructors can simplify the learning process and make it more engaging for students. By leveraging interactive lessons and simulations, students can develop practical skills in diagnosing and troubleshooting voltage drop issues. Electude’s guided self-discovery approach, combined with its dynamic animations and comprehensive learning materials, empowers both instructors and students to unlock the power of lab scopes and excel in automotive diagnostics.
