Lights Not Working

[taduebner]

We have a 2014 Cardinal 3800FL. The underbelly lights, front docking lights, light under the exterior steps, light under the interior step to living room (usually goes on when exterior door opens) quit working. There is likely a burnt out fuse, but we have been unable to locate the fuse for these areas. Any ideas?

I had a similar problem on my 2005 HR Next Level Toy Hauler. One day while towing home from storage, I lost all my trailer lights and electric brakes. After taking it to a local RV shop for repairs, they traced it to a bad ground. There was a stud that was welded to the frame and it had multiple grounding wires on the stud. The nut on the stud had loosened causing the problems. Cost me $80 for the fix. I would check ALL grounding areas, both at the battery and all frame contacts.

Good luck!!!
