Jacks won't extend/retract problem solved

I have a National Tradewinds 7370 that sat for 2 months and the jacks wouldn't come up. Called Power Gear and they said bleed them to get them up, but then they wouldn't work at all. Got Power Gear manual and after several calls replaced the dump valve. Tonight I found a fuse and wire that provides power to each of the selenoids to the jacks. PTL jacks now work as they should.

After almost two months of working on the problem off and on, they now work. It was of great benefit to have the Power Gear manual to track down wiring and power problems. I will say now I know a lot more about my coach. Fortunately I was at home and not on the road.

Thanks to all who sent in suggestions. Arnold

    Awesome thanks for the update. Should help somebody out there some time and some place. I can't even say how many times some tidbit online has helped me out of a jam from 7 or 8 years ago. :)
