Start with the fault you can describe.
Bring the whole problem
Object, cable, power supply, broken part, manual, previous repair, and a clear account of the fault all help.
Respect the stop line
The table excludes live electrical work, damaged batteries, gas appliances, medical equipment, and unsafe testing.
Leave with a next step
A repair, part code, diagnosis note, recycling route, or professional referral is useful even when the object stays broken.
