Suspension dump light won't go out

[mbulriss]

OK, the title sums it up: the suspension dump light on the dash does
not go out. Always seemed a little slow going off after the tag axle
aired up, but now it just stays on.

All suspension air bags *are* fully aired up. Checked the Clippard
valves in the front load center on advice from Ralph - no leaks found.
Crawled around under the rear listening for air leaks and checking
the air bags. No leaks heard, but of course that for sure doesn't
mean there aren't any, based on older ears!

Any ideas on what to check next?

Thanks,

Mike,

Did you cycle the system several times?

Kurt,

Yes, I have cycled it several times.

Also, after finding all bags up, we went out for the weekend and drove
around looking for bumps after remembering a couple old posts on that.
After about 50 miles it finally went out. On the way back from the
weekend, it never went out over the 100 mile trip. It does not go out
at all any more. I was thinking there is a sensor/air valve somewhere
that is stuck, sticking, gunked up?

I think your problem is a pressure switch failure. Why would you think an air leak would cause your condition??

Mike, my old coach will do the same thing. I wonder if in that switch that controls the light, maybe some electrolysis may be occurring?

Thanks Rob,

Can you point me to where is that located?

Mainly because the rear suspension lost pressure after about 30-45
minutes while I was washing bugs off the front end.

Open to any more ideas......

light is powered off a timed 60 second relay. K38. ig powered.
tripped by a 30#pressure switch K38 no buzzer. ( if the same as a
94pt)since ig powered it should go out with key off. there must be
a diode between the tag and suspension dash switch or tripped relays
that I need to find because I cant drop tag only and when I drop
suspension the tag runs up to 100# plus so I always drop tag and
main . the fuse that powers the relay for the suspension also does
the backup lights. I hate having toad functions mixed anyplace in
the formula.

two switches front and rear. I'm in KY digging a hole. but had
access to some pdf. must be aft the dump valves, follow the
hissing. may be one of those fixes that require a pit or jacks.
wouldnt want to tug on a pressure swithch holding up wiggle out room.

Ahhh, that explains why the light always seemed slow in going out
after the tag was filled.

> since ig powered it should go out with key off.
It does.

Time to check my prints and look around K38 if the same as 91, but I
kind of doubt it.

Mike,

Just had a simmilar problem. There are three pressure switches on my coach, that activate that light. I found after trouble shhoting that the tag axle pressure switch was bad. We did the trouble shooting by disconnecting the leads to the switch. high up middle of coach near tag. it was a pain but we got it figured out. BB had the parts
