Synopsis

Start with the symptom. Finish with the fault.
The breaker that won't hold. The motor that hums and trips. The lights that brighten when the dryer runs. The PLC input that's on at the sensor but off in the program. Most electrical books explain how circuits work. This field manual starts where you actually are, in front of a fault, and takes you to the cause one measurement at a time, telling you what your meter should read at every step.

Built for the job, not the classroom

• 115 Fault Cards. Each one handles a single symptom and works on its own: Fast Path tests, causes ranked by likelihood, expected readings, the traps that fool experienced techs, the repair, how to verify it and what to tell the customer.
• A 116-symptom Symptom Finder. Look up what you see in plain words ("trips the instant it's reset", "contactor chatters", "lights glow when switched off") and go straight to the right page.
• Two levels on every card. The Fast Path for the experienced electrician in a hurry; "Why It Happens" for the apprentice who wants to understand.
• Expected Readings tables. What a healthy circuit reads at each test point, and what each wrong reading means.

Everything in one book
Meters used right (ghost voltage, LoZ, clamp placement, insulation testing) · opens, shorts and ground faults · breakers and fuses that trip · GFCI, AFCI and dual-function devices · neutral problems · hot and burnt connections · low, high and unbalanced voltage · stray voltage and shocks · three-phase systems and transformers · generators, transfer switches, solar and battery backup · control circuits · starters, contactors and overloads · motor testing · VFDs · sensors and 4–20 mA loops · PLC inputs and outputs · intermittent faults · LED lighting and 0–10 V dimming · HVAC electrical faults · EV chargers.
Learn the method behind the cards
SPLIT-7, a seven-step method that expert troubleshooters use on every fault, including the ones no book can list. Then practice it: 24 case files told through real readings, 100 Find-the-Fault drills with worked answers, and 80 clear diagrams.
Made to use on site

• Large 8.5 × 11 format with readable type and clean black-and-white diagrams
