Technician A is correct because a common issue that can affect all gauges at once is a blown fuse. If the fuse that provides power to the instrument cluster or gauges is blown, it can result in all gauges not operating. Technician B is incorrect because if the instrument cluster ground is open, it can affect more than one gauge or potentially all gauges and instruments in the cluster, depending on how the vehicle's electrical system is designed.
