Mysterius cable on battery pluspole shoe

[Greengrass]

The battery plus poleshoe broke yesterday so I have to fix a new one.

But how do I get the old one lose?

And what is the wire/cable that is connected to it?

[Greengrass]

In fact there is four cables connected to the shoe.

a big red one, probably the main plus electric

a thin blck one, connected separate

and then two cables which goes threw a sort of box

when I turn the whole cable, it makes a clicking sound.

My suspicions:
Have it maybe to do with alarm or immobilizer?

So, typically.....

You'll have a single thick red positive cable that is soldered into the terminal post. Then around 5-6 cm down that cable, is a black box that branches out two further red cables. One goes to the alternator, one goes to the inside of the car.

the thin Black one sounds like something someone has added - you'll need to follow that.

Typically, you cut the terminal post off, add a spade connector and use a bolt on style post. Or you could use Jay-Kay-Ems solution - I have!
