Emergency! Generator maintenance urgent! Everything dead.

Friends of the Swedes bomber, I am standing here in Holland (Alkmaar) and have a big problem. On the way home to the accommodation the red lights of death and hint “generator maintenance urgently” went on. I then drove still about 5 to the accommodation, then also the servo etc. with corresponding warnings failed. Now the good truck (V70 3 D3/D4) stands in front of the door, electricity is basically completely dead, closed and mirrors opened in slow motion. yesterday and overnight I had a bike mount with flasher and brake light on the AHK. No plan if there is a connection, plugs I have pulled now anyway. Someone a clue what is going on? Probably unfortunately the LiMa, or maybe only a cracked V-belt? At least I look up tomorrow morning. Tomorrow noon we have to go to Bonn. Such a bullshit… Thank you very much for any help! Felix
