A resource for safe and effective troubleshooting from the leaders in simulation training.

Welcome back! If you have gotten this far, you have completed all of Simutech Multimedia’s troubleshooting process steps, and you have finally replaced the defective component of a malfunctioning circuit. You are now a hero among your co-workers and managers because you have just diagnosed and repaired a malfunction that was costing your company thousands of dollars in production line downtime. But before you bask in the glory of your accomplishment, there is one last troubleshooting process step you must complete.

On the last TsT, we learned how to repair and replace a defective component within a malfunctioning circuit, and how to test it to make sure that after changing the part there are no other contributing factors to the electrical malfunction.

Today, we will be discussing the importance of a proper follow-up after troubleshooting an electrical circuit.

After replacing the defective part in a circuit, and determining that everything is operating correctly, there is value in trying to figure out why the malfunction occurred, to assess the likelihood of it happening again.

When the equipment has been repaired and put back in service, you should try to determine the reason for the malfunction.

  • Did the component fail due to age?
  • Did the environment the equipment operates in cause excessive corrosion?
  • Are there wear points that caused the wiring to short out?
  • Did it fail due to improper use? 
  • Is there a design flaw that causes the same component to fail repeatedly?

The answers to these questions can save your company a lot of time and money. Through this process of analysis, future failures can be anticipated and minimized.

Many organizations have their own follow-up documentation and processes. Make sure you check your organization’s procedures and adhere to them.
