Au début, je suis désolé que je vais écrire uniquement en anglais, mais j'ai peur que le traducteur en ligne fera désordre

Hello after long period of time!
At first, I'm sorry that i will be write only in english, but i'm afraid that online translator will make mess

As the title says. We (me and my three friends) have similar problem in our 480.
Two people had changed alternator. Two didn't ;) Alternator is brand new. After this operation dashboard looks like on the photo:

(this is photo from one car-only in this car display shows STOP, so this is not important)
Screenwasher, battery and brakes bulb constantly lighting.
When I disconnected from the alternator wire which is responsive for the start of the charging, discotheque goes off.
What should we check?
Kind regards/Meilleurs voeux du froid Polonais, Adrian
