Common when the DC ESS BUS has a hiccup, ENG MSTR SW is gone burger, or the Engines fuel HP valve isn't interested either.
ENG FIRE P/B (no bottle). All associated valves will reset once the switch is pushed back in. Aside from the engineering questions prior to resetting, of course.
Does anyone know if the accessory gearbox is still turning below 18% N2?
