The 3131 series — in C, L, and M configurations — powers generators, construction equipment, and industrial machinery that operators depend on to run when called upon. The stop solenoid is the engine’s primary safety control: it cuts fuel supply to the injection system when de-energized, ensuring a complete, fail-safe engine shutdown on command. When it fails, you get the two classic failure modes: the engine won’t start (solenoid stuck closed) or it won’t shut off (solenoid stuck open) — both are serious issues on equipment that often operates in isolated or safety-critical environments.
