When diagnosing equipment issues, the initial step is usually what?

• A. Replacing components
• B. Visual inspection
• C. Running automated tests
• D. Consulting manuals

Answer: (B)

Starting with a visual inspection is essential because many faults reveal themselves through what you can observe without taking anything apart. A quick look can uncover obvious clues like loose or damaged connectors, frayed wiring, corrosion, burned or melted insulation, fluid leaks, missing panels, or warning lights showing an abnormal status. This step gives you immediate, low-risk information to guide the next actions and helps you avoid unnecessary disassembly or part replacements. It also helps you form initial hypotheses about the problem and prioritize what to test or replace. After noting what the equipment shows, you can move on to more in-depth diagnostics, such as targeted tests or consulting manuals for step-by-step troubleshooting.
