Current circuit question Omega 2.5TD Facelift 2000

Moin, some of you may still know me from Lichtenfels. I haven’t been in the forum for a very long time. Now I have a problem with my Omega 2.5TD Facelift. He got an AT motor, he has always been in trouble with the battery before and unfortunately he still does that today. Therefore the following questions… Data before: Omega 2.5TD “Facelift”, charging voltage at 14 volts, i.e. controller OK, battery new. Starts with the new battery perfectly, everything is in order. g, when switched off, it pulls 0.6 amps out of the on-board network (measured with DMM). After pulling the fuses, the fuse to slot 12 turned off the “silent consumer”. Now, my question: Which consumers hang on the circuit altogether? After pulling the fuse, the turn signals no longer work, the instrument lighting is dead, the optical confirmation for the ZV is also dead, opens and closes. Door lighting is not affected and leaks et. There is a vulnerability that should be examined first with the model. It is a hands-free system installed by Siemens, but it is not used. Otherwise, the vehicle is electrically all series and no additional extras. I would like to thank you for good advice and hints and would be very happy if you could “encircle” the problem from a distance. LG Hinnerker
