2003 Sun Voyager hydraulic pump fuse

[Kahaone]

I have a 2003 Gulf Stream Sun Voyager. Actually just bought it ( and already regretting it). Today while putting bedroom slide in, all hydraulics stopped working. Slide was all the way in, and everything just shut off. Cannot move any slide or leveling jacks. I assume it is a fuse somewhere. But that is the problem, nothing is marked anywhere as to what fuse is for what item. I contacted Gulf Stream and they said they cannot help me, as they have no schematics or diagrams of electrical or plumbing.
So, does anyone have a diagram of fuse locations for anything on this RV?
It is a 2003 Gulf Stream Sun Voyager. Please be specific in replies to this model RV. I know each model is totally different, so a reply concerning a 2012 Yellowstone is of no use. Please reply about a 2003 Sun Voyager. Thank you.

BTW, I just bought this a few weeks ago, and am finding more things broken than what are working! Wish I had inspected a lot closer before buying.
