Alarm

[Rick Coleman]

When driving my coach to Indio last Friday approximately every 20-30 minutes I would hear a loud high piched whistle that would last for perhaps 10-15 seconds. It was not from my Pressure-Pro tire system, which was my first thought. It seemed to come from the dash area directly in front of me. Everything seemed to operate properly, and all the instruments indicated normal readings. The gen slide was fully closed. Any ideas??

Rick,

I have a '98 so this might not be relevant to you but I have a "lazy" jack on the rear driver's side that occasionally drops slightly and trips the sensor and sends out the "jacks down" audio alarm that is high pitched. There is no visual on the dash but the pull out control panel shows that the "travel" light is no longer lit and I can see that the light signaling a lowered rear, driver jack comes on. Usually, within 10-20 seconds it goes out. If it stays on then I pull over and check the jack visually and raise the jacks until the "travel" light comes back on then I'm off and going again.
Someday, I'll get under there and check the sensor and jack to see if I can correct.

Anyways, hope that helps.

Thanks Brian. It never occured to me to look there. I will check when I next drive the coach.
I could live with that malady for a while. It really makes me nervous not knowing what it is.
I had a problem a few months ago with a jacks down alarm and maybe it is related. That time the jacks were up and the alarm howled non-stop. Turned out the system was low on hydraulic fluid. Fluid was added and all was well. Perhaps I have a small leak in the system.

I also have a "Lazy" jack at the rear Driver's side. When it drops it sounds an alarm and there is an illuminated "Jacks down" readout on the dash. Yours may also have the dash light but have a burned bulb at that position.

I have an '05 and I think the visual indication of the "Jacks Down" is in the odometer LCD. Also, on the '05 you can operate the "Store" jacks without operating the parking brake.

However, if this were a jacks down alarm, I think it would alarm until the jack was stored.

Hi Rick,
I also have a lazy right rear jack, the warning horn is the same as when I'm storing my jacks prior to departure . Loud and obnoxious. I also have a red light on the warning panel. By turning on my HWH panel and hitting the store button the light goes out and the horn stops immediately. Jim

By turning the key to the left or "aux" prior to raising the jacks, that irritating, loud buzzer noise will not occur. I've had the same DS rear jack drop a little when going down the road and the buzzer will really grab your attention. I read on a previous thread that leaving the key in the "aux" position until the HWH lights cycle off, should stop, or at least greatly reduce, the frequency with which the jack drops down of it's own accord.

Jeff:

I raise my jacks from the AUX position, too. It hasn't affected the frequency of alarms while driving. It's always the same one, LR.

It's to the point I don't even look down anymore when I reset the !@#$%^ thing, nor do I let off the throttle. Drawer out, hit the on button and then the Store button. Sound stops.

I suppose the next time I see an HWH tech, I'll ask him to check for leaks or a bad sensor, but it has done this since day one (5/02).

The lcd readout on the odometer does not read jacks down! All shows normal.

I read somewhere the driver side jack creeps because it is close to the “HOT” exhaust system. The heat expands the hydraulic fluid causing the jack to creep down, setting of the alarm. I think for newer models a heat shield was placed between the exhaust and the rear driver side jack. ('02 38FDDS)

I too have had the alarm come on when driving, drivers side rear. I have resolved the problem by letting the jack’s cycle through and shut down by cycling off. I usually run the cycle one more time as I am leaving. I have rarely had the problem now.

RedHotSoup and Rusty Bear:

Both intriguing ideas. I'll investigate the first and try the second. Thanks guys!

RedHotSoup has it right. HWH confirmed to me that is the problem. WRC and HWH both said the only fix was to do a "Store" which could be done while driving, and the alarm would go out. I have had this problem occur up to 3 times in one driving session when the weather is hot. Very annoying to say the least. And, yes, it is always the drivers side rear jack that causes the problem.
