What is the first step when inspecting interior electrical components?

The first step when inspecting interior electrical components involves turning each light on and off. This initial action helps to establish whether the electrical components are functioning correctly. By activating the lights, you can quickly identify any immediate issues related to power supply or bulb failure, which gives a clear starting point for further investigation.

After successfully testing the lights, other aspects of the system can be examined, such as checking for damages, looking for frayed wires, or testing the batteries. These steps build upon the initial check and help ensure that all components are safe and functioning correctly, but starting with activating the lights gives an immediate and practical insight into the state of the interior electrical system.
