Which action should never be performed during AFV shut down?

• A. Never cut high voltage harness (unless cut location marked by manufacturer)
• B. Disconnect 12V battery
• C. Turn off vehicle
• D. Place in park

Answer: (A)

High-voltage systems in AFVs require special handling. Cutting a high-voltage harness isn’t something you do unless the manufacturer clearly marks a safe cut location. HV circuitry can stay energized after the vehicle is shut down, and cutting those cables can cause dangerous arcing, short circuits, or unexpected energy release that could injure rescuers or occupants. Safer steps to take during shutdown are to disconnect the 12V battery to kill the low-voltage systems, turn the vehicle off to stop all power, and place the transmission in park to prevent movement. These actions help de-energize and immobilize the vehicle so you can work more safely. If the manufacturer provides a marked cut point for HV cables, follow that specific guidance; otherwise, avoid cutting HV harnesses.
