Training path
17 chapters, built in the order a technician actually needs them. All of them are live.
Written for working technicians, and not yet reviewed by one. Treat it as a well-researched draft rather than a verified reference.

Hazard recognition, permits, PPE, and working around live process equipment.
Identifying every energy source, isolating it, and proving zero energy.
Voltage, current and resistance as they actually behave in a control panel — and how to measure them without lying to yourself.
Meter categories, clamp meters, loop calibrators, and choosing the right tool.
Three-phase induction motors, contactors, overloads, and why they trip.
Drive fault codes, parameters, and telling a drive fault from a load fault.
Proximity, photoelectric, encoders, PNP vs NPN, and 4–20 mA loops.
Seal-in circuits, interlocks, permissives, and reading a rung like a sentence.
Scan cycle, forcing, and proving whether the fault is field-side or logic-side.
Valves, cylinders, air preparation, and diagnosing slow or stalled actuators.
Pumps, relief valves, contamination, and reading pressure like a symptom.
Belts, chains, couplings, gearboxes and bearings — wear patterns and what they mean.
Why misalignment kills bearings, and what a vibration signature is telling you.
Electrical schematics, P&IDs, and tracing a circuit across sheets.
A repeatable method: symptom, split-half, evidence, root cause, verification.
Communication, expectations and the person at the machine — the half of the job that is not the machine.
Work orders, compliance records and handover — the part of the job that is still working in six months.
