Which statement about battery feeder fail light is true?

• A. It illuminates due to a battery feeder fault.
• B. It illuminates due to a generator failure.
• C. Both a battery feeder fault and a generator failure illuminate it.
• D. All of the above

Answer: (D)

The battery feeder fail light is a warning tied to the essential power system. The essential buses in the Beechjet rely on power from either the generators or the battery through the battery feeders. If the battery feeder itself has a fault, the essential buses lose proper power and the lamp comes on. If a generator fails, the system detects the loss of generator power to the feeder circuit, which also triggers the warning. Because the indicator is designed to flag loss of power to the essential buses from either source, it can illuminate for either condition. That’s why the statement includes both a battery feeder fault and a generator failure, and why “All of the above” is the correct choice.
