307 - battery lamp is on.

my problem is this. When I was going on the road first, I started to hear the sound of the loom by the right wheel. gas was increasing to pressure. I stopped, I opened the hood. the timing set came from those sides. I couldn't see anything because it was evening. I slowly kept on my way. until he got home. When I approached the front of the house, the battery lamp came on. I guess that the car cut the charge at that moment. I wonder if a part of the charger is out of place. I said I would share it here without taking it to the master since I do not fully understand it. I would appreciate if you help.

Without such forums, we would go without understanding and give them whatever money they want. thank you in advance ..

I understood what you said. So is it expensive? I guess it has no repair, we need to buy a new one. Do you have any information about prices?

Thanks for your help ..
