Bad Alternator-like symptoms after installing new alternator.

Greetings,

I have a 2002 CL55.

one day It started with a “Battery Charge Visit Workshop” warning.

shortly after the command screen said “start engine or COMMAND will shut down” and the ESP and BAS warnings appeared before the vehicle would eventually die completely.

I have since replaced the battery any the alternator and after two days, the same thing happened.

I am completely lost in where to look next.

Could have been the voltage regulator in the first alternator but you changed the whole thing so something else must be messing up the electrical
