Hello, after a strange error with the pathogen line to the alternator (see also here pathogen line I find with horror after successfully believed repair, that the entire 12V net has failed in the living area. Nothing is possible, not even the query on the panel, how charged the living room battery is. All relevant fuses are completely. All cables fixed and mass ok. It has not been worked on. The main switch on the charging unit is except Function. The on-board network is neither switched on nor off. The living room battery has enough power. The main fuse directly on the battery is complete. Can the failure of the 12 V on-board network have to do with the repair on the LIMa or pathogen cable (see LINK above)? Thank you for help!
