The program was fine. The input was lying. And the night shift had an alibi.
A comedy-mystery engineering series
Every failure
leaves a clue.
Usually a
loose wire.
Baffling breakdowns. Suspicious components. One technician following the evidence — and occasionally the wrong cable.

Our investigative procedure / 002
Less guessing. More evidence.
Every case follows the same trail.
Even when that trail leads behind a panel.
The incident
The factory stops.
The panic starts.
Someone says, “It was fine yesterday.”
The red herrings
Blame the code. Blame the night shift. Briefly consider supernatural activity.
The forensic breakdown
Measurements, schematics, and the actual engineering. No hand-waving allowed.
The culprit revealed
Meet the five-cent component that held an entire production line hostage.
FIELD NOTE 01Start with the symptom. What should happen, what actually happens, and what changed?

Meet the detective / 003
A technician.
A meter. A suspicion.
I'm William. I've spent more than a decade in electrical work, with hands-on experience in industrial controls, PLCs, drives, and machines that choose the worst possible time to stop working.
Fault Finds turns that troubleshooting into a mystery you can follow. We'll test the theories, explain the engineering, and give the tiny culprit its moment of infamy.
“The machine isn't haunted. Probably.
Let's check the schematic.”
