Since the ship came back from a cruise, the crew's on standdown for awhile and most have gone on leave. I'm the only CTM on the ship.
This morning I was rousted from bed (standdown, and it wasn't my duty day) by a CTR3.
"Bucher?"
"Yeah?"
"Hey, get up, the Divo wants you to look at some of the equipment in SSES."
Groaning, I get up and lurch my way up a few decks, cursing on coming back before my duty day (saturday). "What's the problem Sessions?"
"The Divo wants you to look over the ACCESS. We'd been having problems with it when we were deployed."
"What kind of problems?"
"Well, we put in a CasRep on it 6 times."

"So why isn't there anyone from Spawars here (The Civilian tech grunge guys)? What's the problem now?"
Without saying anything CTR3 walks across the space and flips a switch. Near where he was, there's a sudden noise and a few sparks go flying. I can smell the burning fuses.
"Holy sh*t! Why didn't you call Spawars?"
"Well, you did go to the C school for this thing...got your notes?"
And after much deliberating and studying a glancing, Lonestar came to the conclusion he had no idea how to fix it. Once pressed why he didn't, Lonestar said it was because that's eltech stuff and Jesus, I'm only human. I've only been in the Navy for a year, and they didn't cover 'sploding racks for troubleshooting in school. (well, they did, and I think it's a power supply problem but, surprise surprise, we don't have any more power supplys and there's no way in Hell I'm going to try to fix it. Power supplies was the one place I sucked at in A school)
Civilian Tech guy comes in a week. You learn something new everyday, I say.

Couple more guesses;-
1) isolate the problem. Is it with the feed on the lighting circuit or is it a problem with the lighting circuit itself? The latter will be a lot easier to fix.
2) A problem with the feed into the lighting circuit (which sounds like what you are looking at) may need a temporary bypass from a separate power feed. However, make sure that lighting circuit is secure first - if that's where the problem lies, you are just going to screw up another system, to add to your worries.

Once you've checked the lighting circuit for shorts etc, it's time to make sure it's the PS output. You could do this first, but it makes sense to check the lighting circuit as well (you could have 2 faults, not just 1).
If you've got an oscilloscope handy, try checking the output from the power supply. USE RUBBER GLOVES.
If it's FUBAR you'll see a non-sine wave running at levels way outside what it should (spikes on the line).
If it's REALLY FUBAR then it will fry the scope. Aren't you glad you wore those gloves?
