Peugeot 106 energetically (almost) dead

Hello everyone, until this afternoon apparently nothing indicated that my Peugeot would get 106 start problems. Even this evening everything seemed to be still normal when I put the ignition key in the ignition lock. The car radio went on, all the indicator lights lit up as usual. But when trying to start the engine, the starter only jerked at once, and then immediately for the first time. When again he did not react at all. adio no longer on – i.e., it did not go beyond the attempt, since it was obviously not sufficiently supplied with electricity. Neither turn signals, light nor brake light go. Only the interior lighting, immobilizer lamps and the valve lighting get electricity. But they all extinguish as soon as I try to turn on the blower. The V-belt on the alternator sits tight and is intact (it is, there is somewhere else a second V-belt that I would have missed). I didn’t check the fuses because of the darkness and because I can’t find the manual. But it seems very strange to me that almost the entire electrical system has failed and the valve lighting goes out as soon as you want to turn on the blower. What happened there? And can someone give me a hint where I can download a manual? Thank you for your interest and (hopefully) clarification.
