Sorry. It didn't mean for my previous reply to sound as if I was angry or mad at anyone. I also thought I had mentioned that I had already checked that. It turns out I might have said that in a PM that I got a while ago and not in this topic. Anyway. Back to the subject. I thought that this: X = discrepancy from checklist, meant that the X STANDBY PWR OFF light IS ON, which in turn meant that it was off and not on, whereas for me the checklist is right and there are no discrepancies. So I thought that if mine are working, and yours are not, then it could have something to do with the loss of power that you are experiencing. It would be nice to know if others with the problem have the same results when going through the checklist. These two: DC Meters - on BAT, positive indication on DC Amps. DC Meters - on BAT, negative indication shown on DC Amps. are interesting. I too thought the opposite would apply. A bug maybe? Mark

Well, I certainly didn't think you were angry or rude.  I was confused by your post, but I see that my post was confusing.

OK, so, my copy of the Normal Procedures says:

* BATTERY switch - Guard closed
* STANDBY POWER switch - Guard closed
* Verify that the STANDBY PWR OFF light is extinguished.
* BUS TRANSFER switch - Guard closed
* Verify that the TRANSFER BUS OFF lights are extinguished.
* Verify that the BUS OFF lights are extinguished.

As we see, though, the lights that should be extinguished are on.  So, that's why I was saying the actual behavior is different from the checklist.

In my post from yesterday, I said that the behavior may be correct and the checklist wrong.  However, I thought about the 757.  Both the 737 and 757 have an AUTO position for the STANDBY POWER switch.  In the 737, it's set to AUTO with the guard closed.  In the 757, if the switch is in AUTO, standby power is available with just the battery.

If I open the guard and move the standby power switch to BAT, I get standby power.

Now, I'm no Captain Lou, but it seems like the checklist is correct and the aircraft behavior is wrong.  Whether or not that has anything to do with the battery drain, I don't know.
