GAH! I owned one of those for 12 years but can't remember where that fuse is. I am not sure I ever found it. I suspect it's an inline fuse very near the hydraulic manifold under the hood on the passenger side.
Anyway, did a lot of work on that jack system. I liked how easy it was to fix. Here's my ad free articles about it:
Power Gear jack system
PowerGear=Milwaukee Cylinder. Might check all the fuses in the control box under the dash next to the drivers left foot first.
Just was reading the comments on that article and it says the main fuse is just before the control box under the dash, not under the hood. An inline fuse.
