What could cause a failure of the feed solenoid in the MQ-9?

A failure of the feed solenoid in the MQ-9 can indeed result from an electrical short. The feed solenoid is an integral part of the fuel delivery system, and it relies on electrical signals to operate properly. If there’s a short in the electrical circuit that powers the solenoid, it could lead to the solenoid not receiving the necessary power to function, ultimately causing a failure in fuel delivery or control.

Electrical shorts can occur due to various reasons, such as damaged wiring, improper connections, or exposure to environmental factors that can compromise electrical integrity. Once a short circuit occurs, it can disrupt the normal operation of the feed solenoid, leading to issues in the engine or fuel management system.

While mechanical obstructions, fuel contamination, and software glitches can cause other types of failures in aircraft systems, they do not specifically relate to the electrical operation of the feed solenoid in the same direct manner as an electrical short.
