Thanks Bud, agreed 7 pages was too long to go through, so I am creating a new subject. The CO monitors are brand new, got them last September or October with 5 year life span on them from last year. Under bottom steps there is a co detector breaker location, but I do not think there is any breaker. Looks like a place holder. it looks like a button, but its not. So I think you are right, direct connection to battery. I'll check, not sure why it just went off out of the blue. Unless wire came loose maybe.
I will snap a pic when I get to it this weekend. I thought it was as you say, but did not see how it worked. Because on far left there are some with switches, on far right side, including CO detector along with some others have like red glass like thing. But it does not slide or click or move. One would think it should have a breaker. Also you do not think there is anything to do with that up on topside console? I am hoping I did not accidentally do something when I was updating radar.
