737 Max 8 Loses Electric Power Mid Flight

Another clue perhaps?

After starting both engines - which required messing around with the ELEC1 and ELEC2 hydraulic switches to do so. I turned Gen1 and Gen 2 on and APU Gen OFF/APU bleed off, but I am seeing 2 symptoms-

  1. An ELEC warning on the dash
  2. An OHP Battery discharge warning which probably means the gens are not working.

ELEC warning

OHP battery discharge warning

I currently haven’t found a way to get the battery to stop discharging when in this state, but in the time I took to write this note it disappeared. There was a long delay though which is strange. Definitely something weird going on.

EDIT: UPDATE
And there I have it, on same flight I get black screens and lights and OHP etc during cruise. Presumably when battery drains.

Electrics & lights & screens suddenly all OFF during cruise


EDIT: UPDATE2
As someone else suggested turn on GROUND POWER (in cruise LOL) and everything is back working like it never stopped in the first place. You have to keep GROUND POWER ON though, turn it off and everything goes dark again.

All working and illuminated after turning on GROUND POWER switch during cruise
