Need Help Hlcu + other loads fuse blows when starting the engine

[Hubn]

Hey, Ive been on a big trip threw Europe. On the way home the cooling fan stopped working, than the speedo gave up and now all lights an accessories dant work either. I don't know if the problems are related or not.

Does anybody know what the issue might be?
Any starting points would be really appreciated

Most likely a negative wire came undone. Check all the negatives, starting with the battery.
Obviously after checking all the fuses

Yeah so for everyone having this problem in the future. The solution for the faulty speedo and the hlcu Fuse was to replace the light bulb in the front. and I'm still confused how that affected the speedo speedo
