What is the general procedure for checking the ignition system during an inspection?

• A. Inspecting electrical wires only
• B. Inspecting spark plugs and ignition leads
• C. Testing fuel levels
• D. Checking air filters

Answer: (B)

The correct procedure for checking the ignition system during an inspection involves inspecting spark plugs and ignition leads. This is crucial because spark plugs generate the spark that ignites the fuel-air mixture in the engine's cylinders, and any issues with them can lead to engine misfiring or failure to start. Similarly, ignition leads are responsible for delivering high voltage from the ignition coil to the spark plugs. Checking these components ensures that the ignition system is functioning properly, which is essential for optimal engine performance and reliability.

Inspecting electrical wires alone would not provide a comprehensive assessment of the ignition system, as it neglects critical components such as spark plugs and ignition leads. Testing fuel levels is also not directly related to the ignition system, as it pertains more to the fuel delivery system rather than ignition functionality. Checking air filters is focused on air intake and does not evaluate the ignition components necessary for combustion. Therefore, inspecting spark plugs and ignition leads provides a thorough evaluation of the ignition system's performance.
