My mercedes 91 300 e has a new battery and the alternator is charging, yet something in the system is draining the battery completely dead. What could be doing this.

The alternator is good, yet something is draining the battery completely to the point that it has to be put on a charger, a jump start wont work.

You can use test light between battery post and battery (disconnect) and pull fuses 1 at a time to locate circuit that has draw. light is bright until the right fuse is pulled and it goes out or gets real dim.
