Hi. A week ago I bought a 2000 National Dolphin, Ford chassis with Powergear hydraulic manual levelers. They work fine, but every so often they just stop working. After a few days they come back. We just parked in a site, try to level, and half way into it they stopped.
I checked all the requirements (park, brake, all correct), checked the fluid with all jacks retracted, perfect level. When I try to level I can hear the relays clicking, I can check voltage at the main round selenoid (I think, 2 inch round with 3 cables: one bringing power, one providing power to the pump, and a small one that I believe activates it). I measure the voltage in the small cable going in and when I press any botton it gets 13.3V, but no output. Any ideas?
IMHO the secret to the problem likely lies in a ground or two.
As much as we would all like to just give a SIMPLE fix you need to get your coach on a really good pad (CONCRETE) and jack it up on jack stands then roll around and clean and reconnect the wiring on the jacks, and the control modules. After 16 years the connections tend to start to loose their connections and become unreliable, This tends to happen often after the Coach has been sitting and the corrosion starts to set in. I've had to do this a couple times on my Coach and it's a 2005.
Need - creeper - jacks stands or blocking - small wrench set - 1/4' drive set - anti corrosive spray - rags -sand paper (nail file) - electrical spray - time and patience.
90% of the time this is the problem.
