Park Brake bell

[RanPam]

I have a 2001 Monico Diplomat with a park bell problem. I have read all the old threads that I could find and still have a problem. When I release the parking brake and put the coach in any gear, the park bell goes off continually. I have replaced the Nason switch, serviced the jack reservoir, replaced the park bell relay and fuses but with no luck. There appears to be about 6 wires going to the bell. Does anyone know what else is tied into the bell? This also causes the cruise control not to work. I have no other indications on the dash. I also have a scangage d and there are no codes. Any help would be appreciated.

That issue on the Monaco products has always been the Nason switch. There are about 25 iterations of the switch, did you replace it with the same one. One test I found for a defective Nason switch (maybe you got a bad one) is to slam the brake release quick/firmly down and see if the alarm still sounds.

Depending on the jack system, the three jack models are to be adjusted with the front jack extended 6" inches. If the jack alarm sounds, with the ignition on, fill the reservoir until it stops and then retract the jack.

Lastly, if the issue can't be found, you may need to tie the Nason switch wires together making it think the brake has been released. You may even want to do that as a test to see if it is a switch issue.

try pulling the fuse for the leveling jacks when my jacks are fully up the chime stays on,, I pull the fuse and it stops and I live with it , put the fuse in level and it is good til I raise the jacks, then I need to pull the fuse but you need to look each time to be sure jacks are returned to the raised position, have not figured out how to fix the issue yet. May not be your issue but worth a try.

The jack reservoir alarm is a "chime" in your coach, kinda like the dong you hear in an airplane to fasten seat belts.
The brake alarm is a loud buzzer.

Superpro, you need to add fluid into the reservoir, Dexron III.
If you have never replaced the fluid and depending the age of your coach, I'd do that also. Maybe repeat several times so the old fluid gets circulated out of the jacks.
I got a small 12V Oil Extraction Pump for Automotive from Amazon like $20.00. It made the draining and filling easy as the reservoir is in a real awkward place.

Thanks for all the suggestions. I have eliminated the parking jacks and low air pressure. I made sure that the Nasson switch was the same one as I removed. I took the old switch, cut off the pressure end and tried tying the wires together in 3 different configurations ie, a and c, b and c, and a and b with no luck. Not having the cruise control is the biggest issue. Someone recommended the neutral safety switch on the trans, but I cant see how that would be the issue. Still looking for answers.
