hi guys, i need some ideads for a small (i hope) electrical issue. my 69 barracuda notchback interior dome wont shut off.

So there's an alarm in the mix? That wasn't disclosed initially. Sounds like you need to delve into your installation of that alarm system
the alarm has been in for a while with no issues. this just started the other day. its a viper alarm which r pretty alarms. it also happened during the build of the car before the alarm was installed. right now the car is in my backyard and covered. during the summer id go out to my hot tub and the dome light would be on. id dissconect the battery and it would be good for a couple of days then do it again
