Everything started with .....

As I told them, everything started with a short of the windshield windshield engine, from there it continued with the ignition coil (I already bought it) and the diode plate (they already changed them) and it was there where the mechanic or did not armo the alternator well, that's why the noise in the tensioner or damage, now another doubt is that according Will it give me another short circuit? Or what I do can guide me. Thank you, the truck is a Town & Country 96
Note: The truck I notice that it is very dry in its plastic components with nothing are broken and there are some very spent pieces and with anything they break down

If the failure is already repaired, you will not have problems of new cuts unless they are from another place, that this dry is normal for the year and the climatic components also affect in large cantitad.
