11/44 power problem... (Oh, not again...)

Same machine, new problem. ^_^

Whilst out in the garage playing with the 44 (which I still don't
have an OS for...), my kid sister and one of her friends come
out to the garage to smoke. (They're not allowed to smoke in the house.)
Anyway, while the 44 is running, her friend says, "Wow, that's loud!",
to which Monica replies "This one's louder!" and turns on the KS10...

You know what's coming. And we had christmas tree packages and such all
over the garage, too, so navigating the garage in the dark was real fun...

(For those who didn't see it coming, the garage breaker went...)

Anyway, after resetting the breaker, waiting for the VAX to reboot,
checking that the KS10 was still in working order (I wouldn't be
mailing if the KS10 was broken. I'd be busy burying my sister. ^_^)
and putting back all the boxes I stepped on or knocked over, it
was discovered that the 11/44 no longer powered on. The power control
lights are on, the RX02 and SCSI disks inside the case work, but
the BA11 (Is that the right part?) will not turn on. When you turn the
switch on the front panel, nothing happens. No click, no fans, nothing.
The breaker on the back of the BA11 did not trip. I turned it off and
back on, nothing happened. I ran the AC power checks in the manual and
nothing happened. I checked the front-panel wiring was still connected,
it was. I pulled and reseated the front-panel control board in the
UNIBUS. Nada. It looks like it should be working, it doesn't smell burnt,
and I opened the top of the BA11 power supply and looked inside, and
it looks really scary (what, with the THIS VOLTAGE WILL KILL YOU stickers
and wires thick as my fingers and whatnot...) but it doesn't look burnt.

Is there a hidden switch or fuse or something in there? That's what it looks
like... Failing that, someone got directions for checking out an 11/44
power supply?
