Emergency Power Always On With External Power

[J Brenner 0]

Hello, I'm trying to power up the aircraft from a cold and dark state. The external power is connected. My steps are:

1, battery on

2, emergency power armed

3, external power on

The emergency power is initially on. I thought connecting external power would cause the emergency power to switch back to the armed state.

At this point the battery is still discharging despite external power being on. In the OHP both EXT lights are on, indicating there's power. The electric page on the synoptic shows there's power, but there's no power to the bus. I've cycled the bus ties, occasionally that works, but most of the time it doesn't. I've occasionally seen a "via fault" message.

Does anyone have any ideas? Am I doing something wrong or is there a maintenance option I haven't discovered yet? Thanks in advance.

I have the same issue as well. I normally wait until engine start to arm this. If not, the battery charges for most of the flight.

having the same problem, is Firecapt32's answer the best solution?

You have to arm the Emergency Power after connecting to ground power, or it never trips off.
