What is the first step in systematic fault finding?

Start by gathering information: what happened, when, any changes made, symptoms observed, to understand the problem.

Replace the most likely faulty component immediately

Isolate and dismantle the affected equipment

Carry out an insulation resistance test

Gather information about the symptoms and history

Which sequence describes the six-point fault-finding procedure?

Six-point approach: gather information, analyse symptoms, identify probable causes, test to locate fault, rectify, verify operation.

Gather info, analyse, identify possible causes, test hypothesis, rectify, verify

Isolate, prove dead, dismantle, replace the faulty part, reassemble, energise

Inspect, test, record the results, report the fault, carry out the repair, re-test

Identify, evaluate, control, record the findings, review them and then communicate

What is the 'half-split' method in fault finding?

Half-split: test at the midpoint of a circuit to determine which half contains the fault, then repeat in the faulty half.

Splitting the load equally between two separate final circuits at the board

Testing at the midpoint to determine which half contains the fault

Disconnecting half of the circuits in order to reduce the test current

Comparing the readings taken from two identical installations nearby
