What must you remember when you begin the fault finding process?

When beginning the fault-finding process, it is crucial to remember the switches you used before the fault occurred. Understanding which switches were activated prior to the failure provides vital context for diagnosing the issue. This prior knowledge can help establish whether the fault is related to the operation of specific systems or components. It is imperative to consider this information, as it can lead you to the root cause more efficiently, especially if the switches are known to control specific functions relevant to the problem at hand.

The other aspects, while they may be useful later in the diagnostic process, do not provide the immediate context necessary for starting the fault-finding process. The order of tasks performed, all components checked, and available tools are significant in their own rights but do not directly inform the initial stage of identifying what might have gone wrong immediately prior to the fault.
