Thanks Ezekiel I just spoke with the mechanic and he told me that he burned the alternator. And the repair is affectionate.
I am sincere as there is Mechanic very honored also there are of another type.
It is also more because they put nervous things that I do not control or be, you could or could tell me if with the data I gave them that the alternator burned is within the possibilities.
that the battery light on the dashboard indicates that in 99% of cases the alternator fails, but that the alternator fails does not explain that the brake gets hard, are two totally different things, being your diesel engine, this one has a vacuum pump that as I mentioned earlier you may or may not share the belt with the alternator, did not your mechanic say anything about the brake?
