The troubleshooting electrical circuits module is one of the important in our series. It forms the building block for all the modules that follow it. In this module we simulate a simple circuit with push buttons, a relay, and a couple of lightbulbs.

For those familiar with our traditional Troubleshooting Electrical Circuits module, this new web based module seems to be similar, but under the hood there are many new features and updates that make this experience quite different. The main intention of this module is to make sure trainees understand the basic concepts of electrical troubleshooting, and are able to read wire diagrams and schematics, put into practice our 5-step troubleshooting process, and use a hands on approach to learning. Let’s take a deeper look.

Getting started with the troubleshooting electrical circuits module

When you first launch you’ll notice one major change: the troubleshooting electrical circuits module is run right out of your browser. To ensure you get the full experience we created a browser test tool to check if your computer and browser are compatible. After launching, you’ll notice our brand new design and the two ways you can access the software: you can explore the circuit, or start troubleshooting.

Exploring the circuit allows you to first become familiar with the software, the circuit, and understand how it is wired up.

The other way to access the modules is with the Troubleshooting tab. Once you start troubleshooting, you will be given a work order. For those familiar with our existing product, the option to select between Basic, Intermediate, Advanced or Genius level faults has been replaced with our new algorithm that decides which fault to present you with next. The algorithm is based on your history and skill set. If you are an experienced troubleshooter, you will progress fast through the modules. Beginner troubleshooting who need added training will get extra faults to keep them learning.

Once you begin, you will also notice that system is rendered in 3D, which allows for more interactivity with the system and for you to immerse yourself fully in the training.

The system is designed to allow you to navigate to each component and explore them in 3D, orbit around them, and learn about their specifications.

Of course no electrical troubleshooting module is possible without a multimeter and some additional tools. Our system is designed to allow you to take measurements and interpret their results.

For an example, in this fault when I press the push buttons I have voltage to the relay, it has picked up but the light bulbs are not on.

With the aid of my wiring diagrams, I am able to trace the problem to the relay itself and proceed to replace it, in this case and as always, I must follow proper safety and lockout/tagout/verify for dead.

With the circuit locked and safety is verified, I can now change the relay, turn the power back on and confirm that the issue is resolved.

Now that my work is complete, and after putting everything away, on exit, I am provided a score. The new scoring method is slightly different from our existing product. In our new product we present a lot more information for trainees to learn from. The scoring is still based on the same principles: Make sure you are following safety rules, don’t change parts you’re not supposed to, and make sure you are following our systematic approach to troubleshooting.

This module has over 40 faults to learn from and is a fun interactive way to learn the basics of troubleshooting. It is also the building block for learning how to troubleshoot more complex components such as control circuits, motors, PLCs, and more.
