RWeigant Posted December 9, 2020 Report Share Posted December 9, 2020 Have a 2013 American Tradition 450 Cummings that beeps really loud when I turn on the ignition and while it's running. Yesterday I replaced the engine air filter. Don't think that would be a factor. I thought the jacks were the problem, so I lowered and retracted them. Brake is on and everything works OK. Nothing I do makes this stop. Any ideas? Quote Link to comment Share on other sites More sharing options...
Chad Heiser Posted December 9, 2020 Report Share Posted December 9, 2020 Do you have airbags/air brakes? Is there an air gauge on the dash? If so I would suspect a low air pressure alarm is the cause.

Ray,IN Posted December 9, 2020 Report Share Posted December 9, 2020 (edited) After you start the engine it usually take about 4-6 minutes for the compressed air system to reach 120 psi, however the low air pressure alarm should cease about 60 psi, which is where low air pressure automatically activates the spring brakes/ emergency brakes/ parking brakes.(they are all the same thing) Air springs usually begin to inflate near 90-100psi. Is the travel light on, on your jacks panel? Have you checked hydraulic oil level in the hyd. jacks reservoir?

I went to bring the slides in and no beeping. Started it up, let it warm up for 5 min and still no beep. What's up? This I don't understand. Found the problem. I have never used the outside antenna (batwing) because we have Dish. I was trying to get TV in the bedroom without any luck until I started looking around and found the coax inside the hole in the wall. I pulled it out, hooked it up and wow, TV. After changing the engine filter I started the engine and got the beep. On another forum one guy said is your antenna up. Well, that was it. I lowered the antenna and life is good again.

The little things are the ones that drive you crazy! While I like Barbarok's gremlin theory, something about it still piques my curiosity. Does anyone have a theory? Why does the deployment of an antenna cause some alarm to beep? Is it and the alarm on the same circuit; is there another bad ground? Is there some sort of an antenna deployed alarm that you use instead of looking at it before you move, just like your checklist says?

Barbaraok Posted December 15, 2020 Report Share Posted December 15, 2020 Different manufacturers put in warning alarms and/or interlocks based up things that they had seen. Guess a lot of previous owners left antennae’s up which were snapped off, probably while under warranty.
