Dinging

Please help us. We have a dinging under the dash on drivers side and have no idea what it is or how to find where it's actually coming from. We just purchased this new to us 2003 Foretravel U320 in May and have been having repairs made to it since we bought it.
A mobile mechanic was supposed to come out today to look at what's going on with the dinging, but he called just now and says he has Covid.
Any help will be appreciated. There are no certified mechanics near us and we are supposed to be fulltime this coming Wed. HELP PLEASE.
My phone number is 951-445-2215  and my husband Jan-Michael's is 951-315-0892.
My name is Shari

There is often an indication on the dash associated with the dinger.  Antenna up, air low, etc.  The sounder is connected to a number of things that can throw a fault.

If the coach isn't aired up, for example, the dinger will go off until you reach about 80-90 psi (I seem to recall) in both front and rear brake tanks.  If that's the situation, just let the coach idle some more until the engine compressor has built up enough pressure in the tanks and it will go out.  (you can also search the forum for "high idle" to tell you how to use the cruise control buttons on the Smart Wheel to raise your idle speed, but stay in the driver's seat if you do that and you'll need to bring it back down to put the coach in gear)

Can you describe when it occurs?  Is the engine running or is the key simply in the "accessory" position.

It dinged all the way from AZ to CA after we had 2 new ACs installed at Premier Coach. We have checked everything and can't find a reason for it. We don't have an antenna, air in tires is ok, air bags are ok and slides are ok. The whole trip ot never stopped.

It only dings when the key is on and the motor is running

It's possible there was an antenna sensor on the roof (it's just a Hall switch and a magnet) that was left when a previous owner removed the OEM antenna (2003 came with an antenna) and they disturbed it when they did the air conditioners.  That would put an "Ant Up" light on the dash.

Another possibility is the room-in slide room sensors being misaligned.  Those are also Hall switches with magnets and are behind the valence/slide surround on the top of the LR slide.  (I don't recall the location for the BR slide)

Are dash air pressures OK (not tires, the A&B tanks which are your brake tanks, also used for leveling)?

How's the dash voltage with the main engine running?

I'll have my husband check the switches. No lights on Dash indicate anything. We have checked the slides. The AC Dash went out right before we got home from AZ., but it was dinging before and after that

after you start the engine, and the air has built up,
is the green travel light on, on the hwh pad?

Do you have any manuals for your coach? If so, look at drawing B-2179. 12volt wiring diagram. Just above the tach and Speedo you can see all the items that are connected to that "dinger". Each one will light up when ignition is first turned then go off if nothing is amiss. With that dinger on, something will be lighted and that will be your problem. Most likely the ant. Up sensor.

Where is the Antenna Up Sensor on this MH?

AFAIK, FOT used a magnetic burglar alarm window switch as the antenna sensor on most coaches.  Half was mounted on the antenna lifting arms, and half was screwed to the roof.  The antenna was usually mounted near the front end of the coach roof.

Thank you everyone for your replies
 My husband will go up on the roof tonight when it cools down and check it out. Hopefully we will find it.

He went up on the roof and there are only two wires where the antenna was. They're not touching. If he ties them together will that maybe stop it or is that not a good idea?

Thank you Richard for the Schematics
 Do you or anyone else on the forum have a video of how to remove the dash. This is the 2003 U320 4010 model

Before you dig into the dash, have you looked at some of the other questions/concerns mentioned?

You don't want to disconnect the sounder without finding the cause (particularly if it's air-related, meaning brakes or leveling, not air conditioning)

In the meantime you can turn the dinger volume lower on a 2003. Lift the dash in front of the driver, start the motor, and the dinger location will be obvious. Should have a volume control on it as I recall.  If not, wrap a clotd around it. Temp soluition - find the cause.

Thank you. We are going to check all of the above suggestions before digging into the dash. I'll keep everyone posted.
You're all terrific and your advice and knowledge is much appreciated.

If you didn't have an antenna when you bought the coach and you drove to AZ without the alarm. Then I would guess the two wires were already in there current condition. Don't think they would be your problem. But with that said if you checked for voltage across the two wires and found none. I would say no harm in momentarily touching together to see if it stops the alarm. If it does. Great. I would be surprised if it did. If not your problem lies elsewhere.
