Leveling jacks worked 3 months ago, but won't work now. Doesnt even seem to be taking any current. fuse looks good. Is there another fuse?

I doubt if there is another fuse. You might look for a solenoid close to the hydraulic pump or mounted directly on it.

First thing would be to see if any voltage is getting to that solenoid when you try and lower the jacks. If no voltage then you'll have to start back tracking from there.

If there is voltage you might try tapping on the solenoid. If that doesn't work then try replacing the solenoid. If that doesn't do it then the only thing left is the pump.

Do you have the wiring diagram for the jacks?

Smile Problem solved.... kind of

Turns out I had an electrical problem. Funny thing was I couldn't detect the problem in the leveler switch box. So I cut the wire to the ignition, hot wired into another switch. While doing that I noticed the other end of the leveling switch wire from the ignition was now hot. So i wired back into that and all is good. But now my dash lights, turn signal and back up are out. 4 way flashers working. Going to start a new post.

Thank you all for your advice.
