Dear members of the board,

I noticed that the symbol in the central information display does not change from "battery" to "220V plug" when i plug in 220V.

I measured and found out that the charger underneath the fridge is getting 220V but there is no 12V output.
The contact from the charger is using three pins, positive, negative and one thin wire (probably a sensor of some sort?) does this third wire trigger the charger ? or is my charger shot ?

Edit :
The charger has the following part no : 7H7 915 681
(The 220V fuse is "in")

Thanks in advance

:)
