Question

Quizplus · Accepted Answer

Technician A is correct because a completely assembled electric motor, especially in the context of automotive applications, is designed with safety in mind and is unlikely to expose live electrical parts that could cause a shock. Technician B is also correct because turning off the ignition in a Hybrid Electric Vehicle (HEV) typically causes the system's main relay to open, which isolates the high voltage battery from the rest of the vehicle's electrical system, effectively disabling the high voltage system to ensure safety.
