Most Georgetown owners should remember both the 15a fuse inside the box, and the red flag. I think the hydraulic pump operates just below the 15a limit and I have reset that flag numerous times. I did however recently replace my house batteries. An additional note though, I did replace a slide control switch. The kitchen slide was causing the 15a fuse to pop, so the hydraulic pump wouldn't work. I took the black wire off the switch,took the short away and the pump operated. Thankfully the kitchen slide was in when this occurred.
