On mine, the slides for the kitchen and bedroom vanity are run by electric motors (both on passenger's side of coach). Each are run through the breakers illustrated in the link above. I have had these breakers trip several times.
The living room and bed slides (driver's side) are operated by hydraulics and have never tripped.
Your jacks should be on a fuse panel inside the front driver's side compartment (under the driver's seat and in front of the left front tire).
Good luck and keep us posted. Someone will help you figure it out.
