Thanks everyone again,
So far I used a multimeter and tested out if there a current going into the old fixture wires.
There are none.
Then I tested the converter box fuse contacts for that region, and that also does not have a current running through.. I’m kinda stuck now on wondering how else to diagnose or fix this?
I’m not sure if it’s connected , but the 12volt socket (with antenna / cable combo) Outlet located near the above cabin bunk area also doesn’t have power.
I have checked all the fuses and none are burnt anymore.
Hope someone might have some ideas for me to check and thanks again very much .
Have a great week.
