GEN Bus 1 off with Ground Power

[FortyOneMk2]

Hello,

After updating to 1.3 I noticed that I'm having issues with AC GEN Bus 1 connecting to the Ground power source.  If I fire up the APU, I can power the bus, but for some reason, when I select ground power, the breaker doesn't seem to be connecting the GPU to the No.1 Gen Bus.  Any ideas?

[Litjan]

Ha, finally! I have the same problem (it works the first time, but not when I try again) - and Tom has been totally unable to reproduce it. We compared all of our scripts (byte count), I sent him videos, we screenshared...it doesn´t happen on his system.

So thanks for confirming I am not crazy!

We will certainly keep investigating. Maybe some crazy peripheral interfering (I run a full HOTAS thrustmaster setup)...

For now I just pretend the ground power source is bad and is missing a pin or something...I can live with the GEN bus off (transfer bus still works), until I start the APU.

AND it only happens after some other source has powered the bus (I call it the bus-virginity-problem)...

Cheers, Jan

without a doubt, our most cryptic bug to date.  we'll keep looking at it.  QUESTION....like Jan, does it connect the first time you use the GPU?

For me the GPU is powering both buses the first time, but same bus fail as above when using the GPU for the second time

Hmm.. I dont get the fail with Gizmo v18, but with Gizmo v20 ill get the error/fail. 

So maybe you are running Gizmo v18  @tkyler ?

[tkyler]

I run both, but indeed, was probably running v18 at the time, as its more stable at handling errors, so I use it for development and Jan uses V20 for teting.....I will try both (tomorrow that is......I'm quite fatigued atm) ...awesome catch!  Fingers crossed for debugging.

FWIW I'm having the same issue. It seems to work fine the first time I use the GPU. I havent tried to connect the GPU before taking off after i switch to the APU. But for sure after landing the issue is there for me.

[Benweston]

I got this too. 

[tkyler]

I'm glad other folks are seeing it, there is no more frustrating bug than one that can't be reproduced.  I think TomS is onto something and I'll be on it first thing in the morning GMT-6.  This one really has me curious.

one more

Same here.

First time it happens after returning to the flight after using the replay function.

Second minutes after shutdown the Aircraft with GPU on and runing APU

Confirmed. Working and not fails with Gizmo ver. 18, not working and fails with ver. 20

Great work on 1.31 guys, although I'm still running into this bug with the latest version.

ETA I saw the response to others further down the forum. No worries!

[Litjan]

Yeah, this particular bug is still under investigation and not fixed with the latest Gizmo beta.

Cheers, Jan

 

[Iain]

To confirm same bug here, Beta Gizmo, left bus off, but only on the 2nd connect to GRD power.

[donoscar]

Just throwing this in here....  I seem to be getting this issue only when using my xsaitekpannels plugin with a lua script taking care of switching both generators on at the same time with one single switch. any one else or pure coincidence?

[Litjan]

This is probably related, donoscar. It seems that when trying to connect both generators "at the same time" (as the GPU does), this problem occurs.

The reason is most likely an underlying computational issue - Ben is investigating it actively and it would surprise me if he doesn´t get to the root cause of this. He always has .

Cheers, Jan

 

[Phantom_A320]

Any update on the bug? Was it fixed in the latest update?

[Litjan]

No it wasn´t. The root cause (in the new gizmo beta) has not been found yet. If it really bothers you, you can always go back to the stable version. I choose to enjoy the much smoother performance of the new beta and live with one gen bus not getting powered - nothing important on that one anyway ;-)

Cheers, Jan
