How it works

Master root cause analysis by working real faults.

Diagnostic skill is judgment: what to check first, what a reading rules out, when an "obvious" fix is a dead end. That judgment comes from working real problems, and most training never puts one in front of you.

The course

Read a little, then work the machine.

  1. Read

    Short lessons teach one concept at a time: what a healthy circuit does, what each reading means, which failures look identical from the outside. Every lesson ends with Check Yourself questions.

  2. Practice

    Guided scenarios hand you a fault the way a shift lead would. You read the gauges, take readings that rule causes out, and commit to a root cause.

  3. Prove it live

    Live sims are full machine simulations with an HMI, schematics, and a meter. You find the cause, repair it, and run the machine clean to prove the fix.

Every unit ends on a live sim, so nothing stays theory for long. You build the habit of gauging, localizing, and reasoning before you touch a setting. That habit is what holds up in front of a fault you have never seen.

For supervisors

Every attempt lands in a dashboard you can read.

Every reading a technician takes and every diagnosis they make lands in a log you can see. When someone misses, the attempt replays step by step. The dashboard shows which faults get misdiagnosed, where technicians get stuck, and who can now diagnose without help.

Sample data. The live dashboard reads from your team's attempt log.

Completed work earns a Fault Finder Academy certificate, so diagnostic ability is documented as it is built, drawn straight from problems solved.
