Technical Fuse control problem

[cauchemarre]

Hello,
I’ve got a huge problem right now. The fuse unit is not connected properly.

This is the table of the fuse unit (it’s in French)
My fuses F2 and F3 (for small lights), the mounts are inverted: I’ve got 2 « + » connections for the F3 and 2 « - » connections for the F2, and they are for both fuse, meaning they are working only if they’re 2 fuses (but it’s not normal).

F9 (for warning lights) keeps crashing, but I’ve checked the voltage and there’s no tension when the hazard switch is off, and there’s the full battery tension when it’s on, meaning it’s supposed to be normal.
I also have a short when activating the right turn (only), literally every electrical component starts to flash, even the fuel pump at the start.

Now the most irritating part… F14 (for windscreen wipers), there’s no tension when the key isn’t on power mode. When I put the key into power mode (before ignition), there’s approximately 10.8V BUT IT IS SUPPOSED TO BE ZERO.
And when I turn on the windscreen wipers control, the tension is max, meaning it’s working correctly.
So I think the problem is coming from the main switch but I wouldn’t be sure of the exact place.

My question is, where would this tension come from, and since it’s not the full tension, it means it’s a short, but from where??? Should I change the whole fuse unit? Anybody else had the same problem before?

This is the wiring diagram of the wipers:

These two are the turning/hazard lights:

And this one is the side lights/number plate lights:

Please, I really need some help!!!!
Thank you.
