I just got home from a camping trip today, and my 2007 Keystone Cougar 301 has this alarm squealing from behind stereo. I've never heard this alarm before. I am at a loss to figure out what this is. I've disconnected the factory LP/carbon monoxide detector in the kitchen, replacing it with a battery powered alternative. So I know it's not that.
When I disconnect both the 30 amp plug and the battery, the squeal slowly fades out. but when I reconnect, it comes right back again.
I've verified that everything else works. The Air conditioner, the hot water heater, the fridge. I flipped all the breakers, I've pulled all the 15 AMP fuses. The only effect I've seen is when I flip the rec/con breaker the sound fades as if it's flipping from 110 to 12 volt.
If anyone has any advice or whatever, I would greatly appreciate it.
Thanks in advance,
Diviner
