THORmx, I think you get that "L. H. Bottle" warning too because you start the engines the wrong way and this is just because you can't start them the right way.
"Right" is using the external power and air and go for "low pressure", "wrong" (because this is only used when no external stuff is available) is the "high pressure" variant with only one shot for engine 3, causing the "L. H. Bottle" warning after usage.
The check lists and the KB article currently collide in their statements and if you start the No. 3 engine with the "high press" setting, you'll loose the "L. H. Bottle" because it just gives you one shot.
The check list from Mark might work but can't be found either in the manuals or the KB, it's a Mark special and he just gained the "Senior 707 Flight Engineer Award" for this, congratulations! :D
There's another flaw.
If only external power (not air) is connected, you have a "Low Press" reading on the AC panel.
I think that air of any kind can only come from the external air or from an operating AC, both things aren't working in this picture.
See here, external power only and you have "Low Press" air available.
