What can an HEI system cause?

An HEI (High Energy Ignition) system can cause electrocution due to the high voltage it generates during the ignition process. These systems create a significant electrical charge to ignite the fuel-air mixture in the engine's cylinders. If a person were to come into contact with the ignition components while the engine is running or during maintenance work without proper precautions, the risk of electrical shock is present.

While other choices may sound extreme or related to safety, the primary concern directly linked to an HEI system's operation is the potential for electrocution from the high voltage. Proper safety measures, such as disconnecting power and using insulated tools, are critical when working on or around these systems to prevent such hazards.
