looking for help or info for following i have a 1996 2.5 tdi ducato and im having a problem either sourcing a alternator or brushes or a regulator box complete with brushes. its a valeo alternator and has no meaningful numbers on it to help . the problem with the present unit is that that one of the brushes is damaged at the contact point with the commie thus giving erratic charging if i could find a set of brushes i could resolder them in place. none of the auto electric people in my area can help thanks in advance
