| To accurately determine the impact of a failure in the ship's service generator on the operation of the emergency diesel generator based on the one-line diagram (like EL-0014 fnaf), I would need to analyze the specific connections and configurations depicted in that diagram. However, I can provide a general understanding of how such systems typically operate |
