With the START PROTECTION switch in the ON position, BATT RLY switches ON, and DC external power applied, the which light will extinguish indicating parallel operation?

Explanation:
When the system goes into parallel operation with external power, the electrical logic intentionally isolates one battery relay to prevent backfeed and to control how power is shared between the batteries and the external source. The light that goes out shows which battery is no longer connected to the DC bus. In this scenario, the second battery relay is de-energized, so its light extinguishes, signaling that battery 2 is isolated while the bus is being powered by the external source (with the other battery relay remaining on as needed).
