Hello all. I know this is an old topic but despite following the procedures as I understand them, the same thing is happening to me. I quote a previous poster;


Battery on
#1 aft boost pump on
start APU
APU bleed open
Isolation valve auto
AC/DC selectors to Standby and APU Gen
position lights on
galley power on
packs 1 on

wait 11 minutes:

radios dead
instrument (altimeter?) sound stops
amps/volts look okay
pneumatics normal with APU running

Then I shut down APU, and battery.
Now, Battery on = no battery power. I am able to flip all switches, but there is no electrical power.

This thread just seemed to fizzle out. Did a solution ever get provided?

Thanks,

Paul
