What is essential to verify before concluding a component is faulty?

To determine whether a component is faulty, taking all necessary measurements is essential. This process involves checking various parameters such as voltage, current, resistance, and performance metrics specific to the component in question. Accurate measurements provide critical insights into whether the component is functioning within its specified limits or deviating from expected performance.

Relying solely on visual inspections or subjective assessments may lead to false conclusions, as many faults may not be visible to the naked eye or could be intermittent. While understanding the system wiring and confirming air pressure are also valuable steps in troubleshooting, they do not provide the quantitative data needed to definitively establish that a component is malfunctioning. Taking comprehensive measurements allows for a more precise evaluation of the component’s operational status.
