What could indicate an issue during an electrical inspection of an RV?

During an electrical inspection of an RV, lights flickering when turned on can be a clear indicator of an issue. This phenomenon often suggests an unstable electrical supply or a potential problem with the wiring or connections. Flickering lights can indicate fluctuations in voltage or a loose connection, both of which can lead to further electrical problems if not addressed. Such symptoms may also suggest issues with the power source or the vehicle's electrical system, which warrant further investigation to ensure safety and proper functionality.

In contrast, having all ports displaying green lights typically indicates that those connections are functioning correctly, and calm electrical connections suggest stability and no current issues in those areas. Loud sounds from the fridge may be concerning for appliance performance but do not directly relate to the overall electrical integrity of the RV as a whole. Thus, the presence of flickering lights is the most telling sign of a potential problem that needs attention during an electrical inspection.
