My stud 55 at my front electrical box doesnt have any 12v current, and is dead. Is there a fuse or relay that might effect this?
Look in the upper right hand corner of the battery bay, 10 amp fuse in an automotive twist-in fuse holder.

I checked that fuse and it looks 'OK'. Is there another place to look?
That circuit goes from the center electrode of the battery bank, to the AC electrical panel (stud 6)on the top of the forward luggage bay to the front electrical panel. Only three spots to check, use a trouble light or a DVM and find out where it's broken. It's probably a bad fuse or a corroded connection.

Did you have 12v on Stud 55 before and now it's not there?
12V was an option from the factory. It may not be connected in the A/C junction box.
The PO had the stereo and some other 12v specific electronics tied to stud 55, thus, it probably had the 12v option. Ill have a look inside a/c box to see whats going on.
The type of fuse and fuse holder they used in the battery bay for the 12V feed is notorious for looking good and being bad, and for internal corrosion. That is almost certainly the problem, but a little work with a test light will tell the tale. Wires that worked rarely disconnect themselves.
That fuse holder was indeed dead. The fuse was good.
Dumb question; is this wire running from the battery terminal to the fuse holder positive or negative? PO had this on the negative terminal.

Apparently my previous answer was too confusing for the common man.
To answer your specific question, the wire running from the battery terminal to the fuse holder is positive 12v.

Negative terminal of which battery?
It should be connected to either end of the jumper between the two batteries. Either the positive terminal of the left battery, or the negative terminal of the right battery. That will give you 12 volts to ground.
i'm sure he's good and confused now ???

Can't imagine why, if he reads it as it's written. It is absolutely correct. The 12v connection can go on either post stated. They happen to be the two posts connected together by the center jumper.
not everyone knows what you do....
on first look...it would be a head scratch for sure.

He has an MC9. If he prints it out and takes it to the bus and looks at the batteries as he reads it, it will be perfectly obvious. It has nothing to do with "what I do". It has everything to do with the way 12v is produced from a 24V bus. I have no idea if an Eagle is a 12v or 24v battery, so it may or may not make sense to you, but I'm pretty sure MCI owners will understand it.
Now, if you'd like to take a shot at answering his questing in a manner that is completely obvious and understandable to everyone, including you, have at it. Otherwise, STHU!
i was not picking at you. just commenting generally...so you STFU. if he knew everything you assume...he wouldn't be here asking . now would he.

Full moon again.
when some one tells you to shut the hell up you just sit there and do nothing. how about tell gumpy to lighten up...
oh that's right, i'm the resident punching bag.
sorry i forgot my place around here. ;D
knowing why 12v. can come from a negative post is not a familiar concept to everyone one on earth.

Most times guys we want to help troubleshoot the issue. Again most times this is an art!
There are many here that can really hit the issue spot on in short order, thats cool.
I know there is a great group here, With many experiences. I will be clear that although I respect all of you, the art in troubleshooting requires steps.
We (includes myself) even though i did not comment, should have. Anyway in the begining as with any question, equipment issue. The Art is following some " same" type structure no matter who your helping in a post, side of road, in person or a field on a phone.
So in closing on Friday my comment is: Experience matters! This respectfull way to find out what the Person/Operator knows. Also other information in front of them thats available to them and To any of us the trouble shooter! This is the Art
Good day
Floyd
ps: i didnt ask if there was a manual or schematic available, my bad. I keep forgetting the steps although 34 plus years at this very same task I still wonder how I forget. Im glad to retire from that 2 hour repair window. When you have 6 trucks down and then drive 80 miles to fix one only to realize a better or proper questioning would have made loading a proper part. Again my friends the Art of troubleshooting
