Leveling jacks don't respond!

[artro]

We bought our 98 Mountain Aire in Florida,
drove it 3000 plus miles to California without
a snag. Yesterday, 100 miles from home,
the HWH jacks stopped responding. I get
a red 'on' lite, I see the yellow light
indicating low position. And, momentarily,
I saw three green lights! but they've
gone away. Attempting to check fluid
level, it seems the fill cap is stripped,
I turn the chrome knob to no avail, it just
goes round and round without going anywhere.
Looked around for fuses, found nothing
significant. I get no warning whistle,
no pump noise, zip. What's my next step?
Call a service person?

Thanks

Artro, the chrome cap it attached with a brad or rivet. Take a flat wrench that will fit under the chrome cap. You can then remove the plug with measuring stick. My HWH tank has done the same thing. Good Luck!

Artro do as winnipooh has said had the same thing on my 98 also once you get it off try drilling a hole thru bell shaped vent so next time the pipe will come out when you turn bell. If your light still are working on pad you may only need to add the HWH fluid which you can pick up at CW or a dealer. The fuses are under dash panel in front of steering wheel. "007"

I hope the issue can be solved easily.
The jacks worked perfectly all the way
from florida. I overlooked the fuses
under the dash. In the newmar, there's
a big panel of fuses above the dash
and there's another big panel behind
the engine grill. Yet only one fuse
referred to the jacks, i.e. 'warning buzzer'.
If I get down under the dash, I'll bet
I find them. The fluid box specifies
Dexron tranny fluid only. I think I'll
know a lot more once I get that dip stick
out. The Mountain Aire, a 98, hasn't
been driven much for a couple of years.
Other than this, it's been flawless.

There maybe a fuse located off pump in its own fuse holder 40 amp black wire + another if required from batt post of pump to chassis battery. HWH Specialty Hydraulic Oil is recommended. In an emergency Dexron automatic fluid can be used. NOTE Dexron fluid contains red dye and can cause staining should a leak occur. DO NOT USE brake fluid or hydraulic jack fluid. Use can damage seals. The oil level should be approximately 1" below top of the reservoir when adequately filled. Thats also with the jacks fully retracted.
I said before if red and yellow lights are lit on pad fuses for pad should be ok just the fuses off pump maybe blown because of low fluid.
All electrical connections, especially ground connections,should be clean,tight,free from corrosion and protected from corrosion. Use battery coating or dielectric grease. There are those grounds again, showing up again, don't forget the GND's,the other half of your battry ckt's.
NOTE never saw fuses under dash on a Newmar they were always easily accessable and marked. "007"

Call HWH. They have EXCELLENT phone tech support. They are only available M-F business hours.
