I would not be as technically minded as yourself. Just to explain to me:
1. Depending on the voltage coming from this am I looking at an expensive repair.
2. You speak of the brush pack. Are you talking about the regulator.
3. I think I had this problem on previously owned W124 models.
It seems I have purchased a high cost maintenance vehicle. As I have said, if you are familar with any further problems I might encounter please let me know. Thanks for the speedy reply.
