Years ago I turned in the over head reading light in my 79 32 ft sovereign
... and I lost lost the lighting in the front of the trailer ... including the galley!@, spit and and step light . Lighting remained in the rest of the trailer . At the time I checked all the fuses and tried following the schematics and cleaned all the wires in the overhead fan light ( where it seemed the wiring seemed to sllnrun to ) no luck . Went t plug in lighting. Just the other day the bathroom lights blew out when turned on .
pump and fan still turn on ... odd as they share a switch panel . The bulbs are all good so I know it's a switchnirnwiringnissue. I replaced the univolt some time ago after the front end issue. I'm at a loss . Without fishing though the whole trailer wiring is there a common problem I'm missing? The right plug on the exterior plug is also out . ¯\_(ツ)_/¯
