Final answer:
A FAULT on the ENG GEN pb indicates a fault or error with the engine generator system. A thorough inspection and testing can help diagnose and resolve the issue.
Step-by-step explanation:
A FAULT on the ENG GEN pb indicates a fault or error with the engine generator system. This could be due to a malfunctioning component or a problem with the power supply. For example, if there is a fault in the generator's voltage regulator, it could result in voltage fluctuations or an inability to maintain a steady power output.
To diagnose the specific issue, a technician would need to perform a thorough inspection and potentially conduct tests such as checking the wiring, examining the generator's control panel, or measuring the output voltage. Once the fault is identified, it can be addressed and resolved to restore the normal functioning of the generator system.
