Mercedes Benz 2006 E-350 does not start at all
The car does not start, the keys don't work. - The Battery is quiet new - I also trickle charged the battery and it does show fully charged - Replaced battery of the key FOB too The car is totally dead. I tried to look through videos for possible causes and tried to check but no such thing found. I looked at the battery area and found a lose wire but not sure where it is supposed to go (pic attached). I am not even sure whether it could be a problem. I would really appreciate if the gurus can review and suggest what I can do.
