i've been doing a little bit of experimenting and i think its the extention cable thats broken. ive tried different sensors with the cable and those connected with it seem to have the issue. is this a common thing?
Can cables go out? < yes. Even though it doesnt seem like there are any moving parts - there is a bit of electronics in them that can wear out over heat. Stress on the cable can also wear them out. None electronic cables can also still wear out over as there is stress when they heat and cool wearing out the wire it self.
