Thanks to all. The inline fuse on the pos wire is OK--not blown and registering proper resistance. The 2001 Taos is an auto-switch from shore to battery (hence no actual switch to perform that function. I will check the 12V power at the back of the converter. The problem is that to trace the wire from the battery to the converter requires pulling it from the frame of the camper...If this has to be done, and I found a fray, would I then try to replace the new wire back into the frame (chassis)?? Thanks again to everyone's helpful suggestions! More soon.
