my 2003 E320
MB sedan was showing display "electrical connectors off" 2 days ago & I last drove the car 2 days ago.....now the car is in the driveway making a "chirping noise under the hood" and it cannot start at all , cannot turn overheadlights on , etc. What is it? Dead Battery
JA: Did you test the battery with a voltmeter? And have you ever changed one before?
Customer: No it's too dark, the small battery was previously changed at an ARCO repair station a few years ago & rear large battery in the trunk area was changed about 1 year ago by my brother.
JA: Are you fixing your Sedan yourself? What have you tried so far?
Customer: No, I just arrived home, its dark, I will have car towed by AAA for repair, just wondered why its making a "chirping noise under hood"
JA: Anything else you want the mechanic to know before I connect you?
Customer: no the car is a 2003 E320 MB 4-door sedan Sedan, the "chirping noise under the hood" is the 1st time this has occurred
