Major hydraulic leak

[karfxr]

Hello again everyone. My new problem just happened today when taking the 2010 Georgetown 330TS back to storage. I pulled into my space and heard a noise and saw that my bedroom slide kept trying to retract although it was already retracted. I realized the noise I was hearing was the hydraulic pump cycling on and off. I shut the vehicle off and when I stepped out there was a massive puddle of hydraulic fluid coming from my RF hydraulic leveler. I haven't checked to see if it was a hose or the seals yet. I have noticed a slight fluid leak from the leveler the last couple of times I've used them but haven't had a chance to check it. Has anyone ever had a problem like this before? I now need to find the fuse or ? so the pump doesn't run as soon as I turn the key on so I can drive it to get checked. Any ideal where I could find that fuse?
It never seems to end!!!
Thanks

It's often a high current "flag" breaker in the same compartment as the house batteries. If present, push the small test button. If the lag pops out the breaker is tripped.

It's almost certainly at least one bad hose. There was a range of years where the hoses bulged and failed after several years. Yours is in that range. Many a person has removed the hoses and taken them to Napa Auto Parts or similar and had new hoses manufactured of the same length.

Pulled into KOA Detroit / Ann Arbour and tried lowering jacks to level . All I got was motor hum. Checked fluid container and found it was low or almost empty ( no fluid on my finger or dipstick. I put 2 qrts Mercon 5 and so far no sign of leaking on cardboard placed underneath ( will check in...
