Airbags don't inflate??

Anyone had this happen?? Hit retract all on Eq Sys jacks. Jacks all come up OK. Start engine and idle 10 minutes for air pressure to come up completely.

Drive away. Ride is like a rodeo bull. I actually "got air" between my butt and the seat a couple of times.

Stop. Discover the airbags did not inflate even though coach ran for 10 minutes after jacks were completely retracted.

Hit auto-level; wait for jacks to extend all the way. Hit retract all. Jacks come up, airbags inflate, everything's great and drive 400 mi with no problems.

So, WTF???

Boowho??

Yes that has happened to us... What my Husband does is after the jacks are retracted, he then puts them down a little way and retracts them again.. seems to work for us. Who knew Boowho?

I had that yo-yo ride about a year ago... Scared the h--- out of me... Bounced my washer/dryer part way out of the cabinet and all our clothes off the bar..

Since then, I hit the retract button multiple times and then I get out of MH and actually look to see that the MH has actually lifted off the tires... By doing that I've not had the problem occur again...

I had the same problem. Now I start coach, let air build, then retract jacks. Works every time now.

Do the same here, start engine, let the air presure come up and then raise the jacks. Had the problem once and haven't had it again. We always double check by walking around to make sure the jacks are up.

Had that happen a couple of times. What a thrilling ride we had in an unpaved campground! Now I hit the jacks up a couple of times after they come up. I also build up air in the bags before I hit jacks up. Then a visual check.

Good Luck

Yes have had this happen too. It seems that the valve that supplies air pressure to the air bags needs to see a certain amount of air pressure before it will dump air to the bags or activates once you power off the equilizer system. If you wait and let air pressure build up, then do a retract you should be good as the valve will open (because of enough pressure and it knows the jacks are retracted). You'll also notice that when you retract and then push the power button on the equilizer pad (to power off the system) you will hear a very slight snap sound from under the coach (of course when you have at least some pressure in the system). That is the valve being triggered to open.
All this is of course is what I have deduced. I am sure there is a better explanation or schematic that someone has.
So you can either wait and let coach build over 75lbs of air then do a retract OR once you have some air pressure on the guages do a retract and once complete make sure you push the power button to turn the system off manually (that's when you'll hear the little "snap" sound). If you let it auto shut off on the power it won't fill the air bags if you originally retracted with not enough pressure.

We also double check the distance betweem the fender the top of tire, about even when air bags are down, about 4" seperation when aired up.

So letting the engine run and build air before raising the jacks makes great sense but when I try that, my Equalizer squawks, squeals, beeps and flashes the "Ignition ON" led and does nothing more. Is there something (step wise) you all are doing to get the jacks retracted with the engine on? As always - THANKS in advance.
