737 locks up

I was using the 737-200 and I was not using the APU or External Power/Bleed Air. After a while, the power went out. The battery had died. Nothing I did could get the power back, including loading the default C172 and getting power and then returning to the 737. I had to exit FSX and start again.

What I found interesting, was that I even switched between the 737-100 (-200, -200ADV, -200C and -200F) and noticed that the ADV was missing its landing gear (as if the activation had failed).

I have submitted a ticket. So Captain Sim will now be aware that this is happening (if they weren't already).

Are you saying you were using Battery power only? Or were the engines running?

It's not about normal-ubnormal.
We are trying to figure out if this is a bug or an user's error.

1. Does this happens every flight?
2. Are you sure the generators are ON?
3. What happens if you ARE using the the APU or External Power for the startup?

For example if someone does not use generators the battery will die, it is normal


Yes, that is what I meant, but I have edited my post.

It did happen every time unless I started the APU before I clicked on any FSX menu items. the APU gen was on.
I tried using the external power and air start when this happens but no joy. I tried the same as Markoz, and the default aircraft with engines running and still no battery power and the engines would not start. I even tried the CTRL E... nothing. Shut down FSX and re-started. No issues everything was working. This happened a couple of times until I put in the electric_always_available=1 line in the config. I know it's not realistic or a fix.

1. NO
2. Yes NO - I was confusing the Engine Bleed Air valves with the Generators.
3. They were not in use when the power was lost. I can't start the APU or turn on EP/BA once the power is lost. I used CTRL+E to start the engines, but I could not turn the generator switches ON to get any power to the aircraft.

This does not happen every flight. It has only happened to me twice so far. I can't "nail" what exactly causes it. Both times I noticed that the landing gear had disappeared (they are the only times the landing gears disappears on me).
Last night, after it happened and I restart FSX, the 737-200 sat at the Gate for 2 hours using only the battery for power (the APU was OFF and EP/BA was OFF) and it still had power. So it has me bamboozled.

This is what I normally do once the 737 is loaded into FSX:

Battery Switch - ON (and then close the Battery Switch Cover)
Simicons Panel - EP/BA - ON
Ground Power Switch - ON
Yaw Damper Switch - ON
Fuel Pump Switches - ON (if no fuel in Center Tank its pumps remain in the OFF position)
DC Meter Selector - BAT
AC Meter Selector - GRD PWR
Galley Switch - ON
No Smoking and Fasten Seatbelt Switches - ON
Window Heat Switches - ON
Pitot Static Switches - ON
Gasper Fan - ON
Left and Right Air Conditioning Packs - ON
Isolation Valve - OPEN
Engine Bleed Air Switches - ON
Position Light Switch - ON

The only difference was that when it last happened, I did not use EP/BA, and so the switches on the Air Conditioning panel, may not have been on (I normally turn them on after I turn on the EP/BA or APU). When 737 lost the power, all the switches were turned OFF except the Battery Switch. The Battery Switch Cover was closed and unable to be opened to gain access to the Battery Switch (seeing as the cover can only be closed when the Battery Switch is ON, I assume that it IS still ON).

@bud7h7 - The engines were OFF when the power was lost. I was NOT using any other source for power except the Battery Switch being ON.

I'm confused now because you replied to CS that the generators were on. With only battery power then obviously in time they will die (although usually too soon in FS). But with GPU power, APU or generators 1 & 2 on, batteries should not drain.

BTW my battery dies after 5 minutes even with APU power, but I think that is another issue that is being fixed.

As I said in my reply above. I usually use the EP and BA, OR APU, once I get into the 737 and power it up. On the occasion where it locked up, I did not use them. When I deliberately tried to drain the battery power, two hours passed without the loss of power using the battery only. Got me beat.

Edit: My apologies bud7h7! You are right. My Generators were OFF. It is not possible to turn them on when the engines are not running.

Hi mark i managed to create the same on mine by letting the battery drain and then putting on the ground power, when the ground power is on it lights up showing there is ground power and when you flick the switch the power meter changes as it should but nothing else will work.

One difference. I could not even get the Ground Power light to illuminate when I pressed EP on the Simicons Panel. Sad

It's interesting why only 3 people experiencing this issue?
Anyone else?
