I thought my CO detector was bad so I replaced it. I didn't take a picture of the writing before hand (my mistake). When I wired it back up, the CO alarm didn't work, neither did the radio. The fuse box also shows that the fuse for the bathroom is bad (not sure what I'm the is on the 15 amp fuse). I tried replacing them with no change. Does anyone have any things to try? How is that CO detector supposed to be wired up?
