Default No power to LH seat - Still searching for correct load center

I have been lurking/learning but finally needed to post to this exceptional forum:

Awhile back I lost functionality of the drivers seat controls. I believe someone ran the seat back against a box I had stored behind it until a fuse popped.

I tested for power at the 2 wire plug under the seat and found nothing.

At this point I turned to full blue BB box and the stack of schematics that came with it.

After crawling around every hidden space I could find I uncovered the following 12v load centers(Reminded me of hunting easter eggs MANY years ago!):

1. Above the drivers seat behind a wooden bin unit
2. Outside, above the headlights behind the Wanderlodge plate
3. Upper right cabinet above the galley
4. Inside the rear closet behind a hidden door on the drivers side

I tested every fuse in every load center I found and all are good.

Digging deeper into the blue box I found the attached schematic. It talks of a "lower front" load center and shows a 'circuit breaker No. 11' for the left hand electric seat. There is a note stating this sheet is for coach no. 75413 or later. Mine is 76390 so somewhere I must have this load center but am absolutely lost as to where they hid it.

Has anyone else had this seat problem on an 88?

Any clues about the secret load center I can't find?

I know I can run another hot wire to the seat and move on, but I would rather discover the solution and resolve it.

I have worked on this bus for a couple years now and am still amazed at some of the things I find packed into hidden places. These are addictively fun!

WAG - - - check ground I had this problem when I first got my coach. Running a new GROUND wire to a different location cured the problem

Above the headlights in that space our SP has a double panel. 1st is on a hinge that swings to expose the 2nd.

Auto reset breaker #21 provides protection to the drivers seat on my 88WB.

Remove the outside fiberglass panel on the front of the coach; on the passenger's side you will see several auto reset breakers with the numbers printed on them.

Upper right of photo you can see breaker #21.

Thanks everyone!

I'll check all the recommendations in the morning. Still 104 degrees outside!

Giderich, My numbers are missing so thank you for the photo. I'll have to relabel them for future diagnostics. I did check for power there when I was checking all the fuses on this panel and it was good.

This tells me the ground problem that KCSS mentioned could very well be it. When I tested the 2 wires under the seat for power, I never thought about checking them against the chassis frame(ground).

I'll report back what I find.

You might also try swiveling the seat while keeping an eye on the wiring. Mine got snagged on the seat frame and shorted. A fuse would have blown, but '91sp has a breaker, makes it easy to find if yer hearing is good

It only took 10 minutes after posting that I would "wait until morning" when its cooler to decide I would sleep much better knowing.

I took a short drive to where I store the BB and in 30 seconds found it was indeed a broken ground wire! I put my tester on the steering column and touched the positive wire and saw 12v.

I'll snake a new ground wire to it (when it's cooler! ) and put this one behind me.

I was so fixated on thinking it was from moving the seat back against an immovable object and thus popping a fuse that I didn't even think to check ground.

Thanks everyone for your help. My forehead was bruising from banging it against the wall.

I have a trip in 3 weeks. It will be nice to move the seat back where it comfortable

Persistence pays off! The ground problem, I mean. Not the bruising
