Hi,
When you say it connects the cabin, do you mean where it goes between the door frame and the door? When you check for power, did you try moving the wiring around to see if there is power on and off indicating a broken or weak connection?
If you have, we need to start tracing the power wire back to the fuse to see where there is power. It's not an easy job, but that is what needs to be done. If you are using a test light for testing, you can pierce the wire insulation to check. Just make sure if you expose the internal wire itself that you protect it with electrical tape.
Let me know if you have questions and if I can help in any way.
Take care,
Joe
