Charging consumer battery on 2007 S550
It's my understanding that on the S550 that the consumer can be charged from the front by removing a plastic cover on the passenger side in the engine department that exposes a tall brass pin. This pin is the positive and the ground can be anything (such as the ground on the starter battery).
Is this information correct? See attached picture.

The SL should survive two weeks parked easily, if it does not, it must have an issue.
