It looks like the alternator is not charging at all. The most simple test is the battery voltage should be around 14 volts with the engine running. A typical 12 volt battery in good condition at 70 degree farenheit should read about 12.5 volts with the engine off. The battery charge light does not come on on Merecedes when the brushes are burned in the regulator assembly. My guess is the alternator has an open winding somewhere if a new brush regulator doesn't cure it.
