Hi guys!

I have some problems starting my 727-100 from cold and dark. This is what i do:

1) Start a flight with the cessna, then, turn off the engines, strobe light, master and avionics.

2)When everything is death, then i load the 727.

3)Turn on the battery, then the apu, then the engines.

4) I start noticing some problems, like some lights on the overhead panel that can't be turned off (Stall warning and some others)

5) Later, when i take off, i can't engage the autopilot. (The switches don't move)

6) If i start the 727 with the engines running, i can engage the autopilot, but it does not hold the pitch angle.

Any help??

Thanks, and sorry for my bad english.

A solution I found was to add the following line to the CFG file of the aircraft under the electrical section:

electric_always_available = 1

I had the same errors other had that after about 10 min of operating the avionics and starters no longer worked.  It appears that the battery either doesn't charge the electical coding doesn't swith over to the generators in some cases.  The only draw back this solution has is you don't have realistic battery life - its indefinit, but it a small price to pay to have you avionics or starters not stop.
