HWH leveling system adjustment

Today was the day to fix something minor that has been bugging me for years-- adjusting the leveling mercury switch for the HWH system.

I'll post this thread for others that might have a similiar problem.

If I used the HWH control panel lights I wouldn't be level. This is what I did---

1- I always leveled the coach with a small level on the kitchen Corian counter top. When this area is level the fridge is also level as are all the doors--- working properly.




2- Find the mercury switch. On my rig it is mounted underneath, about mid-ship, near the mufflers.




It is spring mounted with three adjustment screws. Here is a close up--





Now I sat Cindy down in the Captains seat, explained what we're doing and have her hollar loud because the "jacks down" alarm is going off. Only tool needed is a #2 square drive bit or phillips screwdriver.

When the rig was level before, I was always showing a light on the left side, so I adjusted the screw on that side about two turns upward.

Then you can wiggle the sender with your hand to ensure it is seated properly and all the lights will blink and then settle down. With a little tweeking and a little more wiggling of the sending unit all the lights went out. Now I can level her up without having to get up all the time and go to the kitchen. Cindy could never understand with the little counter level (shown above), which way to tell me to move my jacks . I just got up all the time and did it myself-- She did other things .

It took all of ten minutes to do this and I'm a "happy camper" now

Why did I wait so long----- ?? I just always forgot about it-- until the next time I set up----

Geez, do I ever feel your frustration. Last year, my HWH control panel lights would just not cooperate. I too ended up leveling with a carpenters level on the kitchen counter. Level L to R....get up and check the bubble, readjust, get up and check the bubble etc.etc. Ironically, once level the control panel consistently showed low on the drivers side. After reading the trouble shooting manual and locating the level sensor, it was just as you described, a couple turns on the phillips head and all lights out, level.
Cross that pet peeve off the list

I just bought the RV-Easy Level. It's about $45.00 and the coolest thing since sliced bread. Just set it on the floor, turn it on, there are four lights, one on each corner of the level. The lights are green for level, if one or more are out of level they are red and that's the low side. If the left light is red, raise the left side and so on.

Works great and took 2 minutes. The unit turns itself off after about 3 minutes and you put it away, I just keep it under the Drivers Seat! Best accessory I have ever bought for the Coach.

Max,

I have an Dec 03 chassis and HWH upgraded the leveling system. I don't even have to get my hands dirty to make the adjustment. Once I have confirmed that the coach is "TRULY" level I just go out to the front of the coach, open the hood and adjust the level controls per the instructions provided by HWH that came with my Newmar documentation.

Level Control Board


Level Control Adjusters


Here is another tip for you Max... I pull fuse 15 on the Newmar supplied fuse panel to silence the "Jack Down Alarm".

Oemy--

Hmmmm- I seem to remember at myrtle Beach while you were doing the Ultra Power tune to my rig that you couldn't find the fuse to silence the jack alarm-- We both had to endure that awful noise . You have a different setup than me. I believe you have the Actia -- I don't, but I'll look for 'ole #15 tomorrow.

I also think I have a different HWH system -- But i'll look for that too-----

I was looking for fuse 21... for the Acita display. But, you have the analog dash and therefore don't have it. We pull that fuse so UltraPower and the Acita display don't bump heads during the update as we have the key in the "ON" position.

I bet you have a "Jack Down" fuse... you just need to find it.

Amazing what a difference 1 year makes in what is updated and what is not. If you were to set my rig next to Max's you would swear they were the same if didn't look close.

Oemy,

Atta-Boy---

'Ole #15 it is------- "Good on-yuh!!!".

For those that don't know what we're talking about -it's the fuse to pull to silence the "Jacks down" alarm when doing work with the ignition switch "on". I guess #15 is only on pre- Actia systems. Oemy sez #21 is the one to pull on Actia systems. It's in the fuse panel above the instrument panel on the dash board. Mine is an '02.

Thanks 'ole friend

I never gave the HWH level lights much of a thought. I just use a level like this on the kitchen counter top. Cost about $2.

I have Lippert electronic leveling in My Damon. The auto level setting works fine, but if I get up and look down the coach and get the feeling I am at "mystery spot" I adjust.

But until now I just thought when my levelers went through the leveling sequence and the end result was a wheel off the ground the was what it took to level. Never gave a thought of lowering the low side so the high side wouldn't have to be so high. Live and learn I guess.

Jim, I got that EZ Level, also. I saw it at Camping World and thought it was worthless, not needed, waste of money....all that stuff. Well..........time passed..........I got annoyed..........my wife doesn't understand those bubble levels that well..........so buying this 'stupid' thing has saved us from arguing! Its funny when you see something and don't see why would you need it, but its great when you need it and find out why it was made in the first place!

This is what I use, and they work just fine - IF you have pre-levelled your fridge. In all of this dialogue on levelling, I have not seen one mention of the refrigerator, which is, after all, the primary objective.

I have heard/read that if your coach feels level, it is probably level enough for the refrigerator. Probably true, I don't know.

I do know that what you should do is put a level on the flat floor or shelf inside your fridge, then level the coach according to that. Once level, adjust whatever other levelling gauge you use to agree. From then on, that is what you go by, not what the galley counter, table top, or whatever surface you use gives you.

Yes, they should be the same, but until you do this, that is just "shoulda, woulda, coulda."
