Smart Beds Problem

[Alpine Road Warrior]

The smart beds on drivers side of coach do not work. Smart beds on passenger side do work.
When I push rocker switch up or down there is no sound at all, like there is no power to switches. Have reset vasco system and still have same problem. Anyone have any ideas? I checked the slides and they are working.

Here is what I think I know.
Beds are power-out/power-in, so w/"standard" HWH process, that takes an Extend-solenoid-valve to open and pump to run for extend, a Retract-solenoid-valve to open and pump to run to retract. So two circuits, pump & valve, need signal to operate a bed in either direction. On mine I have two rocker switches on DS beds, one for each, and they have 6 wires to each switch. Red Batt wires go to center 2; two black wires on up legs and 2 on down (either rocked up or rocked down) say Pump and Bed 'x' Cyl. Pretty simple logic to the circuit. So you can check for 12V on the center red wires to see if you are just missing voltage; if so you can tap voltage & run here temporarily, but I'd recommend a 15A inline fuse and don't ride the switch when bed reaches the stops. If you have voltage, you may have a bad fuse in the motherboard. I didn't find any in-line fuses in the loom near the rockers.

The beds tie to the ram rod below w/two jamb nylock nuts back to back against a tab extending from the bed's outside frame. As a get-by, you could undo the outer nut and roll the beds out/in by hand. Then when you want to travel, wrap a series of end-to-end hooked bungees around the coach to keep the bed from opening on right hand turns. It'd take about 16 ea. 18" bungees, assuming ~50% stretch each. If you are somewhat of a hotfoot, might consider a double-wrap, or 32 bungees total per bed, 64 for the pair. You can get bungees to match the color of your coach at many home centers, Target, etc.

I seem to recall Izzy telling me something about the smart bed fuses being on each side of the coach inside one of the other storage doors..not with the other fuses. I wish I could remember more, but I'm getting old.

There is a solenoid manifold for the beds on the basement ceiling behind the water tank IIRC, and there may be a fuse block there (total speculation on my part).

Well, back in the spring we were performing some maintenance on the coach, and I extended the DS Large SB, and as it was coming it, the Nordic Track Pro (folded up) grabed some wires on the way out. I caught it before it did any real damage, but I had to end up crawling into the SB and having the better half take the bed in to tie-wrap up all those wires (what a mess). In the process I must have pulled the connection to the Front SB on that same side, because it would not go in when we tried. So back into the large one, and undid some of the wire ties, until the bed would work properly. Then I isolated the connection, and made sure is was tight, but not to tight, and it has worked fine up to now. So if you accidently pulled any wires, check connections, I don't remember any fuse blocks in there but WRV was as consistant as the wind in the desert.

My 2006 Apex has a number of unidentified in-line fuses buried in the hydraulic compartment, one of which is for the Smart-Beds. You might look there.

Of course, the Apex is different in that the SB's are controlled by touch pads and 8 relays. The later model coaches apparently direct wire the SB solenoids to rocker switches.

SE's also have a handful of inline GM type fuses, but I equated those (dad gum azzumptions) to the solenoid valves @ the manifold. Never thought one might be a pump fuse for coupla smart beds. There certainly isn't any reason WRV couldn't have combined both pump activator circuits from the SB rocker switches on DS to a single circuit & single inline fuse. Pump activation is the same function for any HWH activity regardless (slide, jacks, SBs).

I found the fuses in the hyd compartment. and bing go that was it. It just seems odd to me that both fuses would blow at the same time.

E-Mike Thanks for the idea with the bunges but could not find a store in Port Orchard that had that many cords. So I resulted to finding the fuses.

Thanks everyone for the help.

Just for a clarifier to what mike said. None of the smart bed "controls" go through the HWH control boxes. Mr. Doyle wanted them to run independent of the HWH systems.
