Where is the....

[doo01]

Apologies for the complete noob question. I’m trying to hook up a car battery charger to a W218. I see the ‘+’ by sliding the red cover over but where the hell is the ‘-‘?

Thanks in advance.

The big nut on top of the suspension strut next to it.

What are you trying to achieve? Remember that it's not a good idea to jumpstart one car from another due to modern electronics being sensitive to surges.

Not jump start. I don’t drive the car much. Esp with the colder months coming, I wanted to hook a ctek charger to it.

Leave that cover shut. All of that is +12v and big fuses in there, its got a slidey top to keep you causing yourself damage but sparking of something else ...

The ground is connected to the chassis, so any exposed big nut/bolt that is on the body. However, often Mercedes have a copper coloured post near by that should be used.

The link below shows a LHD W204 car, but look on the right hand side in a similar place...
