It smells like plastic burned the Citroen Saxo

The other day the Citroen Saxo of my colleague Olia in burnt plastic, I thought it was from the air conditioning but it seems to me that it has a broken strap I do not know if it is that of the alternate. My question how many straps carry the saxual next to the alternator that has not been the distribution ... I will try to take photos ...

If any are missing immediately by any of the pulleys at least two, they will be without turning and their channels will be seen,
