Fault Finder's Field Book - Practical Fault-Tracing Procedures & Real War Stories

Fault Finder's Field Book is a practical field reference built around real fault investigations, not generic checklists. It walks through the diagnostic method itself — why guessing fails, the universal six-step fault-tracing sequence, reading symptoms correctly, and half-split testing — before applying that method to 31 real fault stories across electrical/control systems and major instrument types: weigh feeders, pressure transmitters, temperature loops, vibration monitoring, hydraulics, gas analyzers, flow measurement, pneumatic valves, and safety interlocks.Each fault story follows a consistent Symptom, Investigation, Root Cause, Fix, and Lesson structure. The book closes with guidance on documenting your own fixes, plus a Symptom Index and Cheat Sheets collecting every formula and comparison table for quick lookup mid-fault.Written by Aamir Shahzad, Senior Deputy Manager – Instrumentation & Control at Gharibwal Cement, drawing on over 25 years of hands-on field experience.
