Step testing is a professional process, not instructions for removing covers or using a meter. It starts
with the reported pattern and follows the evidence from the point or connected equipment towards the
relevant circuit.
The diagnostic sequence
Confirm the symptom and whether it can be reproduced safely.
Isolate and prove dead before opening electrical equipment.
Use the relevant tests to separate the accessory, connected equipment, supply and circuit.
Repair only the cause supported by evidence, then retest.
Why this avoids wasted work
A dead socket can be caused by the socket, a connected item, a local connection or something elsewhere
on the circuit. Changing the socket first may not solve it.
The result can support a focused repair or show that wider work needs a separate plan.
For an intermittent fault, the useful outcome may be a clearer pattern and next test rather than an
instant repair.
